Safety requirements for grounding:
It is very important that the path of lowest resistance goes directly to the main ground
point.
The ground conductor resistance needs to be less than 0.5 Ohm.
Do not connect other equipment to the same grounding cable as the IRFU. Each piece of
equipment at the site should have a separate grounding cable to a common very low
resistance main ground point.
Connect the equipment directly to the DC supply system grounding electrode conductor
or to a bonding jumper from a grounding terminal bar, or bus to which the DC supply
grounding electrode is connected.
Provide fusing according to Local and National Electrical Codes. Fuse rating must be: 4 A
for -48 V operation.
