Operation This section contains pre-operation checklists, energizing procedures, and
remote and local programming procedures for TeSys™ T and
Motor Logic Plus
™
motor protection relays, PowerLogic™ Power Meter,
PowerLogic Circuit Monitor, Altivar™ drives, and Altistart™ soft starts.
Pre-operation Checklists To verify that the iMCC is operating properly, complete both of the following
checklists before energizing the equipment:
MCC Structure ❏ Complete the maintenance procedures beginning on page 55 and
continuing up to “Insulation Test” on page 66. This initial maintenance is
necessary to detect any shipping damage or loose connections. Do not
energize the MCC until initial maintenance is complete.
NOTE: The following maintenance procedures are not necessary before
energizing the MCC for the first time: Control Unit Removal, Stab
Assemblies, Starter Contacts and Barriers/Insulators.
❏ Perform an insulation test on the MCC (see “Insulation Test” on
page 66).
❏ If the MCC is equipped with ground fault protection, properly adjust and
test the ground fault protective device before energizing.
❏ Remove all blocks or other temporary holding means from the electrical
devices.
❏ Remove any secondary shunt bars from the current transformers. Do
not operate a current transformer with its secondary shunt bars
open-circuited.
❏ Manually exercise all switches, circuit breakers, and other operator
mechanisms to ensure that they are properly aligned and operate freely.
❏ Electrically exercise all electrically-operated switches, circuit breakers,
and other mechanisms (but not under load) to ensure that the devices
operate properly. This may require an auxiliary source of control power.
❏ Verify proper interval and contact operation of the timers.
❏ Set the Motor Logic Plus overcurrent setting to the maximum service
factor amperage of the motor to ensure that the proper overload
protection is provided. The Motor Logic Plus overcurrent threshold is set
at the lowest setting at the factory. Verify that all other settings are
optimized for the application.
❏ The Parameter Settings Sheet lists all the parameters that have been
changed from the original, default settings. Any settings not shown on
this sheet will retain their original, default values.
❏ Verify that all load and remote control connections have been made and
that they agree with the wiring diagrams provided.
❏ Verify that all ground connections are made properly.
❏ Install the covers and close the doors; verify that they are all properly
tightened.
