Connect DC –48 V Power Cable
The following sections describe how to connect all necessary cables to the RU.
Important: Do not use a cable that contains red phosphorus as a flame retardant. This may cause
problems, for example, heat generation and emitting smoke.
Important: Ensure the cable connector gland or clamp is the correct size for the selected cable
diameter to prevent water ingress.
4.6.1
Connect Frame Ground Cable
This procedure describes how to connect a Frame Ground (FG) cable to the RU.
Prerequisites:
■ RU mounted and not powered up
■ Available AWG ground cable with two hole lug (green or green with yellow stripe, 0.625 mm hole spacing)
■ Weatherproofing method to prevent moisture intrusion
■ 13 mm socket
■ Philips screwdriver
Danger: Use properly insulated tools and perform all safety
precautions in accordance with local safety practices when working
on or around power terminals, power cables, and power connectors.
Contacting power terminals, uninsulated conductors, cable wiring,
or any connector that could be part of a live electrical circuit can
result in death or serious personal injury.
