6.5 Entellisys system test kit (Entellisys only)
The Entellisys system can be tested with the Type
ETSTESTKIT03 test kit, a portable instrument
designed for field-testing of the Entellisys system
functionality. The test kit user manual is DEH-503.
6.6 Final steps to be taken before
energizing equipment
The following steps should be taken before
energizing the equipment:
1. Manually exercise all switches, circuit breakers,
and other operating mechanisms to make certain
they are properly aligned and operate freely.
2. Conduct an electrical insulation resistance test
to make sure the switchgear is free from short
circuits and grounds. This should be done both
phase-to-ground and phase-to-phase with the
switches or circuit breakers both opened and
closed. This test should be performed with a
1000 volt meggar. Disconnect all control circuits
before checking resistance.
3. Check any electrical relays, meters, or
instrumentation to determine that
connections are made properly and
the devices function properly.
4. Electrically exercise all electrically operated
circuit breakers, and other mechanisms (but
not under load), to determine that the devices
operate properly. An auxiliary source of control
power may be necessary to provide power to
the electrical operators.
a. (Entellisys Only):
Using the Entellisys HMI, exercise all
EntelliGuard circuit breakers to determine
all devices are functioning correctly. For
Entellisys HMI instructions, reference DEH-501.
5. Test the ground fault protection system
(if furnished) in accordance with the
manufacturer's instructions.
a. (Entellisys Only): Test all protective functions
using the Entellisys Test Kit (ETSTESTKIT03).
Reference DEH-503 for instructions.
6. Set the adjustable current and voltage trip
mechanisms to the proper values. Experience
has indicated that damage from faults can be
reduced if the devices used for overload and
short circuit protection are set to operate
instantaneously (that is, without intentional
time delay) at 115 percent of the highest value
of phase current which is likely to occur as the
result of any anticipated motor starting or
welding currents.
7. Make certain that field wiring is clear of live
bus and, where necessary, physically secured
to withstand the effects of fault currents.
8. Check to determine that all grounding
connections are made properly.
9. Remove all debris, scrap wire, etc., from the
switchgear interior before closing the enclosure.
10. Install covers, close doors, and make certain
that no wires are pinched and that all enclosure
parts are properly aligned and tightened.
