Pow-R-Line switchboards
EATON CORPORATION www.eaton.com
CAUTION
FAILURE TO DISCONNECT CONTROL POWER DURING SWITCHBOARD
TESTING WILL RESULT IN FAILURE OF ELECTRONIC COMPONENTS.
Failure to disconnect control power during switchboard
testing will result in failure of electronic components and
void manufacturer’s warranty.
Surge protective devices (SPDs)
Prior to testing the switchboard, disconnect line and neutral
connections to all SPD units in the switchboard. Keep hardware
in a clean and protected environment to guard against damage
until re-installation.
CAUTION
FAILURE TO DISCONNECT LINE AND NEUTRAL DURING TESTING WILL
CAUSE THE TVSS AND SPD SURGE PROTECTION SYSTEM TO FAIL AND
WILL VOID THE WARRANTY ON THE DEVICE.
Failure to disconnect line and neutral during testing will
cause the SPD surge protection system to fail and will void the
warranty on the device. After testing, re-install all connections.
The following label will appear on the equipment:
Pre-energizing switchboard insulation testing
Exercise extreme care to prevent the equipment from being
connected to the power source while tests are being conducted.
Prior to energizing the switchboard, perform a Megger or DC test
of the switchboard’s insulation. With the neutral isolated from the
ground and the switches and/or circuit breakers open, conduct
electrical insulation resistance tests from phase to phase, phase to
ground, phase to neutral, and neutral to ground. Retain results for use
to compare to results produced in the future. A form for recording
test results is provided in the Appendix of this document. Prior
to testing, remove all control power fusing and connections to
products, which will be damaged in this test. See above.
WARNING
TO PREVENT DAMAGE TO GROUND FAULT CONTROL CIRCUITS,
METERING CIRCUITS, OR OTHER CONTROL CIRCUITS WHEN MEGGERING
SWITCHBOARD, ISOLATE CIRCUITS FROM SWITCHBOARD SYSTEM
BEFORE BEGINNING THE MEGGER OPERATION. BE SURE TO RECONNECT
THOSE CIRCUITS AFTER MEGGER TESTS ARE COMPLETED.
NOTE: SOME GROUND FAULT CIRCUITS MAY NOT BE FUSED; THEREFORE,
ISOLATION OF THOSE CIRCUITS REQUIRES DISCONNECTING WIRING
FROM BUSBARS.
DO NOT USE AC dielectric testing.
WARNING
DO NOT USE AC DIELECTRIC/MEGGER TESTING.
Test resulting in readings at or above 1 megaohm is satisfactory.
Post-testing
After testing, and with the switchboard de-energized, reconnect all
devices, control fusing, and disconnects removed prior to testing.
Re-attach surge protective devices (SPDs).
Securing the switchboard
Re-install all side covers, deadfront plates, doors, and trim parts
on the switchboard using hardware supplied by the manufacturer.
Take caution that conductors are not pinched between parts when
installing the deadfront, cover plates, side sheets, and filler plates.
All parts should be aligned and secured when installed. Do not leave
holes or gaps in the deadfront construction. Clean up any debris in
and around the switchboard.
