A.6 Interface Wiring Notes
Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the PDU.
WARNING
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the
mains is required.
WARNING
Alarm relay contacts should not be operated in excess of 30 Vac @ 5A maximum.
1. Use Class 1 wiring methods (as defined by the NEC) for interface wiring up to 30V. The wire should be
rated at 24V, 1A minimum.
2. Use Class 2 wiring methods (as defined by the NEC) for interface wiring from 30 to 600V. The wire should
be rated at 600 volts, 1A minimum and 12 AWG maximum.
3. Use twisted-pair wires for each input and return or common.
4. All interface wiring and conduit is to be provided by the customer.
5. When installing external interface wiring (for example, building alarm, relay output, and X-Slot) to the PDU
interface terminals, conduit must be installed between each device and the PDU cabinet.
6. Install the interface wiring in separate conduit from the power wiring.
7. All building alarm inputs require an isolated normally-open or normally-closed contact or switch (rated at 24
Vdc, 20 mA minimum) connected between the alarm input and common terminal. Building alarm inputs
can be programmed for use with either normally-open or normally-closed contacts. All relay and switch
contacts are customer-supplied.
8. The building alarms can be programmed to display the alarm functional name using the front panel LCD.
9. Alarm relay contacts have a maximum current rating of 5A and a switched voltage rating of 30 Vac and
28 Vdc.
10. Alarm relay wiring should be a minimum of 22 AWG.
11. See Table U, Figure A-45 through Figure A-55, and Chapters 3 and 7 for interface wiring.
12. LAN drops for use with X-Slot connectivity cards must be provided by facility planners or the customer.
