Electrical Installation DC, Method
DANGER
Electric Shock Hazard: Components with hazardous voltage and energy will electrocute operator. Operator shall avoid
touching live components with hazardous voltage and energy. Verify the absence of voltage using an appropriately
rated multimeter.
Always Wear Proper PPE: The proper Personal Protective Equipment (PPE) must be worn while working in close
proximity of hazardous voltage and energy.
Conduit Installation: All conduit connections must be made in such a way as to maintain the NEMA rate of the
enclosure. Failure to maintain the NEMA rating will void the warranty.
WARNING
Turn AC Switch to OFF: Verify the absence of AC voltage prior to landing any conductors.
Turn the external AC breaker OFF: Verify the absence of AC voltage prior to landing any conductors.
Open Fuse Holders: Verify the absence of DC voltage and current.
NOTICE !
Check Polarity of DC Inputs: DC inputs with the wrong polarity may cause damage to the inverter. Check for proper
polarity with a multimeter.
Use Correct Fuses: Make sure to size the fuses according to NEC requirements. If using 30 A fuses, skip every other
fuse holder – DO NOT place 30 A fuses in adjacent fuse holders.

TOOL
DESCRIPTION
#3 PHILLIPS-HEAD TORQUE DRIVER
#3 Phillips-head torque driver, capable of 30 in/lbs
#2 PHILLIPS-HEAD TORQUE DRIVER
#2 Phillips-head torque driver, capable of 10 in/lbs
MULTIMETER
1000VDC/480VAC CAT III Multimeter
Verify that the PV conductors are completely isolated from the PV array prior to landing any conductors in the inverter.
Open the Wire Box following the instructions presented in Section 3.3.5.1 through 3.3.5.2. Open all PV fuse holders prior
to landing any conductors.
Land each PV conductor to the proper fuse holder as shown in Figure 3-22. Positive conductors are on the left and the
negative on the right. Strings should be wired and labeled in decrementing order (top to bottom). Torque connections to
25 in-lbs (2.8 N-m) with a #2 Phillips-head torque driver.
