Only trained and qualified personnel should be allowed to install or replace this
equipment.
AC Powered Main Hub
To connect AC power to a Main Hub:
1. Connect the AC power cord to the Main Hub.
2. Plug the power cord into an AC power outlet.
DC Powered Main Hub and Expansion Hub
WARNING: The protective earth connection should be connected
before proceeding with power connections. Confirm the DC power
source is powered off during installation. Damage to hubs may result
if power is connected improperly.
The DC powered Main Hub and Expansion Hub are intended to be powered by a
+48VDC power source. The hubs are designed for 14AWG to 6AWG wire size
connections. Use only UL listed AWM wire, rated 600V and 90 degrees C.
If wires larger than 6AWG are needed from the DC power source, follow local
codes for reducing the wire size at hub connection point.
Follow local codes for routing of power cables to power source.
The unit should be connected to a DC branch circuit breaker. A suitable discon-
nect device must be provided in the DC branch, either a circuit breaker or switch,
that can be employed to disconnect power to the system during servicing.
To connect DC power to a Main Hub or Expansion Hub:
1. Strip 5/8” (16mm) of wire insulation material off each power wire.
2. Insert the +48VDC wire into the compression terminal at the “+” location.
3. Insert the -48VDC wire into the compression terminal at the “-” location.
4. Bare wire ends should be fully inserted into terminal.
5. Use a flat blade screw driver to fasten the wire inside the compression terminal.
6. For the Protective Ground Wire (Figure 7-5), use 14AWG minimum wire with a
#8-32 stud size ring lug.
