6.2 Grouding

Grouding modules is necessary to reduce or eliminate shock and fire hazards. All module

frames and mounting racks must be properly grounded in accordance with local and national

electrical codes. Proper grounding is achieved by connecting the module frames and

mounting racks continuously using a suitable grounding conductor. The grounding conductor

or strap may be copper, copper alloy, or other material acceptable for use as an electrical

conductor.

(a) Grounding by using grounded clamp

There are two grounding holes with 4.0 mm diameter in the middle of the long frames of the

modules. The grounding between modules must be approved by qualified electrician. And the

grounding device must be produced by qualified electrical manufacture. The recommended

twist torque value is 2.3 N.m. A copper core in size of 12 AWG can be used as grounding

clamp. The copper wire should not be compressed during the installation.
