2.3 Wiring the Inverter – General Requirements
This section describes the requirements and recommendations for wiring the
CSW Series inverter. Before wiring the inverter, carefully read all instructions.
WARNING: Wiring should meet all local codes/standards and be
performed by qualifi ed personnel (i.e., licensed electrician).
2.3.1

Wiring Requirements

• All conductors that are at risk for physical damage must be protected
by tape or placed in a raceway.
• Always check for existing electrical, plumbing, or other areas of
potential damage prior to making cuts in structural surfaces or walls.
• Where DC wiring must cross AC or vice-versa, try to make the wires at
the crossing point perpendicular (90 degrees) to one another.
• DC overcurrent protection must be provided as part of the installation.
• Use only copper wires with a minimum temperature rating of 75° C
(194° F).
2.3.2

Torque Requirements

• All wiring to the DC terminals and DC ground connection should be
checked periodically (once a month) for proper tightness. For the torque
requirements, refer to Table 2-1. If you don't have a torque wrench,
ensure all connections are tight.
