I n st a lla t ion 2 .1 .5 W ir in g t h e I n ve r t e r This section also describes the requirements and recommendations for wiring the MS-PAE Series Inverter/Charger. Before wiring the MS-PAE Series inverter/charger, read all instructions. All w ir in g sh ou ld m e e t a ll loca l code s a n d st a n da r ds a n d be pe r for m e d by qu a lifi e d pe r son n e l su ch a s a lice n se d e le ct r icia n .
I n st a lla t ion 2 .2 Gr ou n din g I n ve r t e r s The MS-PAE Series inverters use two separate electrical systems (AC and DC power), therefore e a ch electrical system is required to be properly connected to a permanent, common “ground” or “earth” reference. An inverter system that is properly grounded limits the risk of electrical shock, reduces radio frequency noise and minimizes excessive surge voltages induced by lightning.
I n st a lla t ion 2 .2 .1 Sizin g t h e Gr ou n din g Ele ct r ode Con du ct or s AC Side - The size of the AC Grounding Electrode Conductor (GEC –AC) depends on the size of the largest ungrounded conductor feeding the AC load center. A #8 AWG (8.4 mm2) copper conductor will serve as an AC Grounding Electrode Conductor (GEC –AC) for AC power conductors smaller than and including #2 AWG (33.6 mm2) copper. See Table 2-1 for additional values.
I n st a lla t ion Method 2 (see figure 2-6): When the AC and DC service panels are near each other, then the AC Grounding Electrode Conductor (GEC – AC) and DC Grounding Electrode Conductor (GEC – DC) can be connected to a single Grounding Electrode. In this method - since there are multiple connections to the DC Grounding Electrode (GEC – DC) - the size of the DC Grounding Electrode Conductor can not be smaller than the largest conductor in the DC system (usually the batteryto-inverter cable).
I n st a lla t ion 2 .2 .2 Syst e m Bon din g Ju m pe r The MS-PAE Series inverter does not include an internal bond between the Grounded Conductor (AC neutral/DC negative) and the equipment grounding terminals. This bond [System Bonding Jumper (SBJ)] is usually done in the main distribution panel for each electrical system. CAUTI ON : There should be one and only one point in each electrical system (both AC and DC) where the Grounded Conductor is attached to the Grounding Electrode Conductor.
I n st a lla t ion 2 .3 D C W ir in g This section describes the inverter’s required DC wire sizes and the recommended disconnect/overcurrent protection and how to make the DC connections to the inverter and the battery bank. Refer to figure 2-8 when connecting the DC wires. W ARN I N G: Even though DC voltage is “low voltage”, significant hazards may be present, particularly from short circuits of the battery system.

I n st a lla t ion 2 .3 .1 D C W ir e Sizin g It is important to use the correct DC wire to achieve maximum efficiency from the system and reduce fire hazards associated with overheating. Always keep your wire runs as short as practical to help prevent low voltage shutdowns and keep the DC breaker from nuisance tripping (or open fuses) because of increased current draw. See Table 2-3 to select the minimum DC wire size (and corresponding overcurrent device) required based on your inverter model.

I n st a lla t ion 2 .3 .4 W ir in g t h e Ba t t e r y Ba n k W ARN I N G: Lethal currents will be present if the positive and negative cables attached to the battery bank touch each other. During the installation and wiring process, ensure the cable ends are insulated or covered to prevent touching/shorting the cables.
I n st a lla t ion 2 .3 .6 W ir in g t h e I n ve r t e r t o t h e Ba t t e r y Ba n k CAUTI ON : Inverter is NOT reverse polarity protected, if this happens the inverter will be damaged and will not be covered under warranty. Before connecting the DC wires from the batteries to the inverter, verify the correct battery voltage and polarity using a voltmeter. If the positive terminal of the battery is connected to the negative terminal of the inverter and vice versa, severe damage will result.
I n st a lla t ion 2 .4 AC W ir in g This section provides information on how to make the AC connections to the inverter using the correct AC wire size and corresponding overcurrent protection. Refer to figure 2-13 for an overview of the AC wiring. 2 .4 .

I n st a lla t ion 2 .4 .5 W ir in g t h e AC I n pu t a n d Ou t pu t The MS-PAE series provides 120/240VAC on the output, but the input may be wired either as a 120/240VAC input or a 120VAC input (to one input only) depending on your AC source. The AC output will continue to produce 120/240VAC with either the 120/240VAC or 120VAC input configuration. W ARN I NG: DO NOT connect 120VAC (same phase) to both AC HOT 1 IN and AC HOT 2 IN inputs. These inputs must be 180° out-of-phase (i.e. 120/240VAC).
I n st a lla t ion 2 .5 I n ve r t e r W a r n in g La be l A warning label is provided to inform all personnel that an inverter is installed in your electrical system. Affix this label in a clearly visible location at the electrical panel that is being powered by the inverter. This is because it might be falsely assumed that the panel is no longer “hot” after the AC power has been shut off, when power may actually still be available due to the inverter automatically powering the panel.
I n st a lla t ion 2 .6 Fu n ct ion a l Te st 1. After all electrical connections to the inverter, batteries, AC source, and sub-panel have been completed; follow these steps to test the installation and the inverter operation. CAUTI ON : Use a multimeter to verify the correct DC voltage for your particular inverter model (i.e.
Ope r a t ion 3 .0 Ope r a t ion The MS-PAE Series inverter has two normal operating routines; 1. Inverter Mode, which powers your loads using the batteries, and 2. Standby Mode, which transfers the incoming AC Power (i.e. utility power or a generator) to power your loads and uses this incoming power to recharge the batteries. This inverter also includes an extensive protection circuitry to shut-down the inverter under certain fault conditions. 3 .
Ope r a t ion 3 .2 St a n dby M ode The MS-PAE Series features an automatic transfer relay and an internal battery charger when operating in the Standby Mode. The Standby Mode begins whenever AC Power (Utility or Generator) is connected to the inverter’s AC input. Once the AC voltage and frequency of the incoming AC power is within the AC input limits, an automatic AC transfer relay is activated.
Ope r a t ion The Charge Mode provides up to four separate charging stages: Bulk Charging, Absorb Charging, Float Charging and Full Charge. Bu lk Ch a r gin g; This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage (determined by the Battery Type selection*) is achieved. The inverter’s green LED stays ON (solid) to indicate Bulk charging.
Ope r a t ion 3 .2 .2 Tr a n sfe r Tim e While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the VAC dropout voltage (80 VAC per leg, default setting), the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances - as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 16 milliseconds.
Ope r a t ion 3 .4 Pr ot e ct ion Cir cu it r y Ope r a t ion The inverter is protected against fault conditions and in normal usage it will be rare to see any. However, if a condition occurs that is outside the inverter’s normal operating parameters, then it will shut down and attempt to protect itself, the battery bank, and your AC loads.
Ope r a t ion 3 .5 St a r t - Up ON / OFF Sw it ch - The inverter can be turned on and off by lightly pressing and releasing the Power ON/OFF switch on the front of the inverter (refer to figure 3-5). When the inverter is first connected to the batteries, or when its automatic protection circuit has turned the inverter off, the ON/OFF switch will need to be pressed to start the unit (or reset per section 4.1).
Ope r a t ion 3 .6 Fa ct or y D e fa u lt Va lu e s Your MS-PAE Series inverter/charger uses default values for the adjustable settings (shown in Table 3-2) that are adequate for most installations. If some of your operating parameters need to be changed from the default values, the optional ME-RC remote control can be used to make those changes. To help you determine if you need the ME-RC remote display, information on the inverter/charger settings that can be changed is provided below.

To reset the inverter: Press and hold the Power ON/OFF pushbutton (see figure 4-1) for approximately fifteen (15) seconds until the Charging/Inverting Status LED comes on and flashes rapidly; once the rapid flashing has begun, release the Power ON/OFF pushbutton. The Status LED will go off after the pushbutton is released.
