1.1.2 Cable
Compartments
Access to integrated components such as
electronic protection relays on standard
switchgear is usually not possible if the module is
energized.
As an outstanding attribute MNS
i
S switchgear
provides separate compartments, one for power
cables on the right hand and another for control
cables on the left hand. The two cable compart-
ments can be provided with different key locks in
order to assure specific access rights.
MNS
iS
motor/feeder cables are housed in their
own power cable compartment completely isol-
ated from any control equipment or wiring. The
cubicle arrangements are configured suitable for
front cable access.
The power cable compartment can be provided
with cable entry from the top or bottom of the
cubicle.
The control cables have their own control cable
compartment completely segregated from the
power compartments.
This control compartment also houses the
integrated motor control units M
Control
and other
associated control equipment.
The control wiring can enter from the top or
bottom as required for the project. External
signals (such as pushbuttons, indicators etc.)
connect directly to the M
Control
main board.
