Important Commissioning
Checks
•
Inspect the equipment for any signs of physical damage.
•
Verify SMC Flex physical installation is complete. This includes physical
attachment to adjacent cabinets, bus bar, power cable and control cable
interconnections with Line and Bypass control gear, and power cables to
the motor.
•
Verify that any apparatus covers and barriers that were removed during
installation have been replaced and secured.
•
Verify the integrity and operation of all safety interlocks.
•
Verify that motor mechanical installation is complete.
•
Verify that Incoming Power wiring to the equipment is complete and all
connections are tight.
•
Verify that Motor cabling to the equipment is complete and that all
connections are tight.
•
Verify that Control wiring between units of the equipment is complete.
•
Check for any damaged components and verify that electrical clearances
have not been reduced while installing power cables or apparatus.
•
Verify Power System Grounding (Earthing).
•
Check if there are any Power Factor Correction Capacitors. (For correct
installation requirements of these capacitors, refer to Installation
Instructions, publicat
).
•
Check if Surge Capacitors and/or Surge Arrestors are installed at the
motor. Open motor junction box and verify it by yourself. These must be
disconnected from the circuit. (Refer to Installation Instructions,
publicatio
•
Verify fiber-optic cables are connected at the right location (FO cables on
Phase-A power pole go to Phase-A on the fiber optic board, Phase-B of
power pole to Phase-B on the fiber optic board and Phase-C of power pole
to Phase-C on the fiber optic board) and the connectors are fully seated in
their sockets.
•
Verify that fiber optic cables from the Interface board are connected to the
proper through-panel connectors at the right front corner of the low
voltage compartment. Note that the cable connectors that mate with the
through-hole connectors are round, not rectangular. The grey gate signal
transmitters on the Interface board connect to the rear 3 grey connectors
(phase 1, 2, 3 top to bottom), and the three blue receivers at the lower left
corner of the interface board connect to the front 3 blue connectors.
ATTENTION: Ensure that all sources of power are isolated and locked out before
working on installed equipment. Verify that all circuits are voltage free using a
hot stick or appropriate voltage measuring device. Failure to do so may result in
severe burns, injury or death.
ATTENTION: When commissioning a MV SMC Flex, it is critical that following
important checks are completed. For more details, follow the commissioning
guidelines that follow this page.
