Secondary and control connections
The switchgear was wired in the factory in
accordance with the project-specific connection
diagrams. Refer to project-specific drawings for
locations of the incoming and outgoing wiring
terminal blocks.
Openings in the side of the switchgear in the
low voltage/instrument compartment area allow
control connections between sections. When
shipped in groups of several frames each, the
factory installs interconnection wiring between
shipping splits. The factory then disconnects and
tags one end of each of the connections, then pulls
the wire bundle back across the split within the
adjacent frame. Reconnect these interconnections
according to the project-specific connection
diagrams after the equipment shipping sections
are installed in place.
Primary cable connections
Area for connection of primary cables is provided
in the cable compartment either through the roof
or floor as indicated in the general arrangement
drawings. The gland plates are made of 1/8"
aluminum — these plates must be used in the final
assembly. Holes for entrance of power cables or
conduits must be cut in the gland plate(s) and a
sealing type bushing used. ABB recommends using
O-Z/Gedney sealing bushings for all installations.
Warning: Sealing bushings are
required for all power cable entries.
Connection to control source
The control source wiring should be properly sized
to support the requirements of the control circuit.
Connect the control source leads to the terminal
blocks as indicated on the project connection
diagrams.
Warning: Route secondary power
and control wiring through the
provided routes.
Use rubber grommets cut with
appropriate size center hole to
accommodate the wiring bundle.
Check electrical phasing before
connecting.
Circuit breaker: lockout, insertion and removal
Notice:
Remove foreign objects,
tools, debris and obstructions from
inside the module before inserting
breaker.
Circuit breakers may ship separately. Remove
the plywood cover over the breaker that is securely
attached to the pallet (figure 8). Untighten both
clamp screws from the pallet (figure 9). Refer to
the breaker instruction manual for more details.
