Installation, Operation, & Maintenance
in a control cabinet. However a cabinet protects the system from dust and mechanical
damage and is recommended.
Power distribution is shown in
from all sources of strong electromagnetic noise. Such noise can interfere with MMC
operation.
Protect the MMC system from all the following:
•
conductive fluids and particles
corrosive atmosphere
•
•
explosive atmosphere
The diagrams and recommendations may be modified if necessary so the wiring
conforms to current NEC standards or government regulations.

Control Cabinet Specifications
The control cabinet housing the MMC:
•
should have a NEMA-12 rating or better. A cabinet with this rating protects its con-
tents from dust and mechanical damage.
must be large enough to provide adequate air circulation for the MMC, drives, and
•
other components. Always allow for adequate air flow through the MMC vents.
•
must have a rigid vertical surface to mount the MMC on.
should be positioned to allow the cabinet door to open fully for easy access to the
•
MMC Control.
Post warnings according to National, State, or local codes for the voltage
present in the control cabinet.

Power Distribution Diagram
The MMC requires an external DC power source. The power distribution drawing that
follows shows an MMC connected to an Analog Interfaced MMC-SD Drive. The
drive's 24 VDC power is supplied via the MMC in this example. If the drive has its own
external 24 VDC supply, the +24 V line would not be connected.
