SECTION 3 | Installation

• For EVO-1224F / EVO-1224-HW: The maximum continuous DC current required is 76A.

The capacity of the Battery Isolator should be more than 76A or more than the capacity of

the alternator, whichever is higher.

3.18.3 Requirement to Keep the Neutral Conductor of Shore Power Isolated

From the Chassis Ground of the RV

As explained in on-line White Paper titled “Grounded Electrical Power Distribution Sys-

tem” at www.samlexamerica.com (Home > Support > White Papers), in the RV, the Neutral

Bus Bar is NOT bonded to the Chassis of the RV. In the RV, the Neutral is oating with respect to

the chassis of the RV. This is necessary for safety because if the Neutral was bonded to the chassis

of the RV and if the Neutral and the Hot got reversed by mistake, the chassis of the RV will be at

120 VAC with respect to the Earth Ground. If a person standing on the Earth Ground touches the

chassis of the RV, he will be fed with 120 VAC and will receive electrical shock!

3.18.4 Typical Mobile Installation

Fig 3.14 illustrates typical RV installation for EVO-1212F / EVO-1224F using 30A, 120VAC,

Single Phase Service Inlet. Fig 3.15 illustrates typical RV installation for hard-wired versions EVO-

1212F / EVO-1224-HW using 30A, 120VAC Single Phase Service Inlet:

 Auxiliary Battery is connected to the DC input connections through an appropriate fuse to

protect the DC input cables against short circuit

 When AC input fr

om the Grid is not available, the Auxiliary battery will be charged by the

alternator through the Battery Isolator

 Battery Charger Temperature Sensor Model BCTS-EVO is installed on the Positive or Negative

post of the auxiliary battery and connected to the RJ-45 Jack for the Temperature Sensor

 Supplementary battery charging is being carried out through a solar array and a Charge

Controller connected to the DC input provided for external battery charger

 AC input to the EVO

is fed from the Electrical Panel of the RV (through suitable breaker).

 If the RV has a 50A Service, 120VAC Single Phase input to the EVO

can be fed from either

of the 2 Split Phase Legs of the 50A RV Panel (through suitable breaker).

 AC output from the EVO

is fed to the Electrical Sub-Panel for EVO

(Use 120V version and

NOT 120/240 Split Phase version of the Electrical Sub-panel)
