Important Commissioning Checks
• Inspect the equipment for any signs of physical damage.
• Verify SMC-50 physical installation is complete.
• Verify the integrity and operation of all safety interlocks.
• Verify that motor mechanical installation is complete.
• Verify that Incoming Power wiring to SMC-50 is complete and all
connections are tight.
• Verify that Motor cabling to SMC-50 is complete and that all connections
are tight.
• Verify that Control wiring to SMC-50 is complete.
• Check for any damaged components and verify that electrical clearances
have not been reduced while installing power cables.
• Check if there are any Power Factor Correction Capacitors (refer to
Power
Factor Correction Capacitors on page 62 of Chapter 2 for correct
installation requirements of these capacitors).
• 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
Surge Arrestor Protection Devices
on page 63 of Chapter 2).
• Verify fiber-optic cables are connected at the right location (FO cables on
Phase-A power pole go to Phase-A on the Interface board, Phase-B of
power pole to Phase-B on the Interface board and Phase-C of power pole
to Phase-C on the interface board) and the connectors are fully seated in
their sockets.
ATTENTION: When commissioning a SMC-50, it is critical that following
important checks are completed. For more details, follow the commissioning
guidelines that follow this page.
ATTENTION: The polarity of the gate drive signals is important for proper
operation. For example, the A+ and A- transmitters from the interface board
must connect to the proper SCRs in the power electronics assembly. See
Figure 37
