Filter Reactors
The mounting provision for the reactors is variable in the left-to-right direction.
There are sliding nuts under the mounting slots that may move while the
reactor is being removed. When the new reactor is placed in position, simply
slide the nuts into position with a screwdriver and reinstall the mounting bolts.
Make sure there is a minimum of 3 in. of clearance between reactors and
between any reactor and the cabinet. There are lifting channels on top of each
reactor suitable for forklifts that will accommodate a single fork for smaller
reactors and two forks for larger reactors. Make sure the capacity of the
forklift is sufficient before lifting reactors (the reactor weight is specified on
the nameplate).
Cooling Fans
When replacing cooling fans, make sure they are oriented in the proper
direction. The airflow direction is indicated by an arrow on the outside surface
of the fan housing and should be pointing outward (out through the door).
Also, make sure the leads are not reversed as this will reverse the fan rotation.
Capacitors and Capacitor Fuses
Before beginning any disassembly to replace capacitors, take note of the
jumper configuration and cable termination locations (i.e. wye or delta
configuration). When torquing connections on a capacitor terminal or on the
top of a fuse, remember to use only 10 ft-lb (13.5 N-m).
