INSTALLATION MANUAL

The MidNite Solar Surge Protector Device (MNSPD) is a Type 1 device, designed for

indoor and outdoor applications. Engineered for both AC and DC electric systems, it

provides protection to service panels, load centers or where the SPD is directly connected to

the electronic device requiring protection. Maximum protection will only be achieved if the

SPD is properly installed. Please read the following installation manual carefully and follow the instructions. The MidNite Solar SPD is offered in three different voltages to maximize the required protection level. Protection is achieved by reducing the clamping voltage to a safe voltage that your system can sustain without damaging any electronics in the system. By using the chart on page 2 select the SPD’s that provide the protection your system requires.

DANGER: Electrical shock or burn hazard. Installation of this SPD should only be made by qualified personnel. Failure to lockout electrical power during installation or maintenance can result in fatal electrocution or severe burns. CAUTION: Check to make sure system voltages do not exceed the SPD voltage requirement and the correct SPD voltage/model has been selected. CAUTION: This unit must be installed in accordance with the National Electrical Code (ANSI/NFPA-70) and applicable local codes.

3. Install green wire to the GROUND bus bar. In AC circuits it is not uncommon to connect the green wire to AC neutral, install the white sleeving over the green wire when connecting to AC neutral. Make sure the green wire takes the shortest path to earth ground!! 4. Connect phase conductors. The phase wires are black and red in color. The orientation is not critical to the operation. (AC) With the POWER OFF, connect one wire to AC HOT IN (line) and other wire to AC HOT OUT (load) as shown in fig. 1.

Figure 1.5 In a utility connected home, one of the most vulnerable points of entry is the service entrance panel. All house wiring connects to the service entrance panel and therefore everything plugged in is at risk. The MidNite SPD300 provides protection against near lightning strikes up to 115,000 amps of surge current. Hooking up to the service entrance can be done in a few different ways. Figure 1.6 shows the two hot wires connected to a 240V circuit breaker.

Figure 1.7 shows a more economical method to connect the SPD to the service entrance distribution panel. This installation utilizes a 240V breaker that is already in use. This could be a deep well pump, air conditioner etc. Unless the circuit breaker is listed to have two wires connected, you must pigtail the wiring as shown. Breakers that are listed for two wires are very rare, so this method of installing the SPD is probably your best bet. Figure 1.7 Some homes have surface mounted distribution panels.
