Safety Guidelines for
Installing and Removing
SecureConnect Units
Units with door-mounted operator handles, switches and disconnects must be in
the OFF/O position before units are inserted or removed.
Unit Support Pan ,
Open the unit door completely and verify that the unit support pan has been
installed.
The unit support pan is secured with two screws on the right side and one screw
on the left side.
ATTENTION: De-energize, lock out, and tag out all sources of power to the MCC
when installing or removing MCC units. If MCC units will be installed or removed
with power applied to the main power bus, follow established electrical safety
work practices. Refer to the publication, NFPA 70E: Standard for Electrical Safety
in the Workplace, for further information.
WARNING: If power sources are connected to the motor control center, use
extreme caution when inserting units. All busbars and the line sides of the
inserted units are energized and contact with these parts can cause injury or
death.
ATTENTION: To insure operator safety and prevent equipment damage, we
recommend that two people install or remove units that are in the upper six
modules or over 1600 mm above floor level.
IMPORTANT The unit support pan below the unit compartment must be in place before
installing the SecureConnect unit.
