Powering Down the UPS
To completely remove power from the UPS:
1.
Power down all equipment being supported by the UPS (attached loads).
2.
Place the UPS in Standby mode by pressing the STANDBY button on the front panel.
3.
Disconnect the UPS from utility power.
4.
Wait at least 60 seconds for the UPS internal circuitry to discharge.
Emergency Shutdown
Compaq UPS R3000 XR models include a Remote Emergency Power Off (REPO) port as
required by the National Electric Code (NFPA 70). The REPO port allows you to shut the UPS
down from a remote location. You can connect the REPO ports of multiple UPSs to a single
switch or circuit to shut down your entire system in an emergency.
IMPORTANT:
The REPO feature shuts down protected devices immediately and does not follow the orderly
shutdown procedure initiated by Compaq Power Management Software.
The REPO feature shuts down devices that are operating under either utility or battery power.
If the UPS was operating on battery power when the remote switch was closed, no power will be
available to the devices until utility power is restored and the devices are manually powered up.
The UPS R3000 XR REPO circuit is an IEC950 Secondary Extra Low Voltage (SELV) circuit.
The computer room Emergency Power shutdown circuit conductors that connect to the REPO
terminals must:
■
Meet the requirements of an NEC Class 2 circuit or IEC950 Secondary Extra Low Voltage
(SELV) circuit
■
Be separated from any hazardous voltage circuits or conductors by reinforced insulation
■
Short the UPS R3000 XR REPO terminals.
■
Disconnect the UPS R3000 XR AC input source.
To shut down the system:
1.
Place the UPS on Standby.
2.
Disconnect the mains by opening the switch or circuit breaker at the utility panel.
WARNING:
To reduce the risk of electrical shock and/or equipment damage, use a
Lockout/Tagout procedure to isolate the UPS R3000 XR from AC power before wiring the
product or replacing a non-hot-plug component.
