MPD-DS-
WM
-FDS Series
Conduit/Cable Installation
In situations where the
metal cable connector and conduit hubs
must
be bonded to the ground system
, t
his can be
accomplished by installing them either by method 1 or method 2 as shown.
Method 1: Enclosures with flange plates using threaded
openings through the flange plate and standard
locknuts. Flange Plate must be connected to the
internal grounding system using jumper wires.
Method 2: Enclosures without flange plates using a hole
“through the enclosure” with grounding
locknut.
These locknuts must be bonded between each other and to the
grounding system using jumper wires. After the entry hardware is
installed, connect the appropriate conduit or cable.
Note: All unused enclosure openings must be closed using
approved close-up plugs with standard locknuts.
Refer to IOM sheet of cable connector for proper installation
IMPORTANT: When connecting conductors:
•
Strip the wire so that the insulation covers the wire up to the
terminal.
•
Make sure all wires are connected to the correct terminals,
per the wiring diagram.
•
Tighten all terminal blocks/screws.
OPERATION
MPD-DS-WML-NFDS Series switches operate with an exterior switch, allowing the unit to be cycled off and on without
the need to open it. Two-position OFF-ON and three-position ON-OFF-ON are the most common setups, and switches
are typically labeled to show the current position.
REPLACING FUSES
Always turn off supply power before opening unit or performing any maintenance! All maintenance should be
performed only by a licensed electrician with knowledge of these types of electrical systems.
In the event you need to replace fuses, disconnect power to unit and open the door of the enclosure. Remove the
faulty fuse(s) and replace with like parts of the same type and ratings. Close uni
t door once fuses are in place and unit
is ready for testing. Ensure the load on the switch is not exceeding the capacity and ratings for the disconnect switch
and fuses, then restore supply power. Refer to the wiring diagram that was included with your disconnect switch if
needed.
