1.
Two redundant PowerNet control networks connect the UPMs to each other and the UPMs
to the SSBM. Each network requires only one shielded twisted pair of wires.
2.
Refer to sheets 2 and 3 for location of the UPM PowerNet Interface Panel.
3.
Use Class 1 wiring methods (as defined by the NEC) for control wiring. Install the control
wiring in separate conduits from the power wiring. Install the twisted pair of each
redundant PowerNet network in separate conduits. The wire should be rated at 24 volts,
1 amp minimum. The recommended wire for the PowerNet network is shielded 22 gauge
twisted pair Belden 8761 or equivalent.
4.
Control wiring run may not exceed 100 meters.
5.
Connect control wiring and terminating resistor (if applicable) to the removable portion of
the terminal block.
6.
Terminate each redundant PowerNet network at the end modules in the system. Use a
120 ohm, 1/4 watt, 5% resistor (Powerware Part Number 141202041). Refer to drawing
164201373---4, sheet 2 for typical termination points.
7.
Install terminating resistors onto appropriate UPM PowerNet Interface Panel terminal block.
Refer to drawing 164201373---4, sheet 3 for terminal location. Connect each resistor
across terminals 1 and 2 and 6 and 7.
8.
Refer to Tables K and L, and to applicable chapters for information about installing control
wiring.
