The factory archives data sheets for future reference.
Control Power Off Tests Perform the following checks before applying control power to the drive.
Rockwell Automation recommends that you complete these checks in the
sequence they are presented here.
Interlocking
When the input contactor option is purchased a key interlock is provided to
prevent access to the medium voltage compartments of the drive unless the input
isolation switch is locked in the open position.
Where the input switching device is provided by others, Rockwell Automation
will provide a key interlock on the medium voltage compartment of the drive,
and a matching interlock for installation by others on the upstream device. The
interlock must be installed in a manner that ensures the power to the drive is off
and the drive is electrically isolated whenever the key is freed.
Although key interlocks shipped with all medium voltage equipment are aligned
in the factory, they often move out of position during shipping or are often
misaligned when the cabinet is set down on an uneven floor. The following
instructions will assist the field engineers in quickly and accurately aligning the
deadbolt key interlock with its counterpart.
ATTENTION: Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from electrical shock, burn, or
unintended actuation of control equipment. Hazardous voltages may exist in
the cabinet even with the circuit breaker in the off position. Recommended
practice is to disconnect or lock out control equipment from power sources, and
confirm discharge of stored energy in capacitors. If it is necessary to work in the
vicinity of energized equipment, the safety related work practices of NFTA 70E,
Electrical Safety requirements for Employee Work places, must be followed.
