Operation
34 Eaton Remote Power Panel (RPP) User’s Guide 164202125—Rev 5 www.eaton.com/powerquality
Shutdown
To shut down the RPP:
1. Shut down the load equipment according to the manufacturer's recommended shutdown sequence.
Load equipment may be turned off at the equipment or at the circuit breakers on the RPP.
2. Turn off all the panelboard circuit breakers.
3. To remove power from the RPP completely, turn off utility power to the RPP.
Surge Protective Device Option
The optional Surge Protective Device (SPD) is shown in Figure 18. Depending on the configuration of the RPP,
the status of SPD is reported either through the three indicators on the unit or through the normally-open
contact monitored by Eaton Energy Management System (EMS). For the location of the SPD, see Figure 6 on
page 12. For specification details, see Table 21 on page 44.

WARNING
DO NOT use the SPD Phase Status LED as an indication of the prescence of absence of system phase
voltages.
After system power has been applied, the SPD automatically begins to protect down-stream electrical devices
from damaging voltage transients. With all phase voltages present, if an LED turns OFF (for Non-EMS
monitored model), or if the SPD alarm is issued on the EMS display (for EMS monitored model), the SPD has
disconnected itself from that phase of the electrical system because one of its Thermally Protected Metal
Oxide Varistors (TPMOVs) has failed. If a TPMOV fails, power will be maintained to the load; however, the load
is now unprotected. The SPD is not repairable and contains no user serviceable parts. If the SPD fails, the unit
must be replaced. Please contact service from Eaton to schedule for a replacement.
