Preparations for Inspection and Maintenance of Equipment (Powering-Off)
1) Stop the equipment and check that the motor has
completely stopped.
2) Press the interlock switch on the operation panel (See Fig. 1 in the next section).
The light on the switch should turn on.
3)
Turn off the external main power supply. Disconnect and lockout the main
power.
4)
Turn off and lock out
the control power supply.
5)
Turn off and lock out
any other job specific power feeding the drive.
6) Wait for 15 minutes or more for the bus to discharge.
7) Verify that all power is removed by measuring the main, the DC bus, the control,
and any other external source voltage levels with properly rated measuring
equipment.
Note! A meter rated for the main circuit voltage is required to safely check the
main circuit voltages.
8) Ground the 3-phase input power supply terminal at the main circuit input
terminals.
9) Perform the necessary maintenance.
