4.1. Connecting the Power Supply Cables
4.1.1. Installing the Power Supply Cable Keepers
The MPC includes cable keepers, which are designed to prevent the power supply
cables from being accidentally disconnected from the unit.
Note: In addition to the Power Supply Cable Keepers described in this
section, a Power Outlet Cable Keeper is also available for MPC-20V series
units. Please refer to Appendix F for more information.
• MPC-8H-1 and MPC-8H-2: The cable keepers for these units must be installed by
the user.
1. First make certain that both of the MPC-8H’s two power cables are
disconnected from the power source.
2. Install the two standoff screws (included with the cable keeper) in the two
vacant screw holes, located between the two power inlets. When the standoff
screws are in place, thread the two screws supplied with the cable keeper into
the top end of both of the standoff screws.
3. Connect the power cables to the power inlets. Check to make sure that both
cables are firmly seated in the power inlet connectors.
4. Install the cable keeper plate, by slipping the plate over the two screws which
protrude from the top of the standoffs. Slip the cable keeper plate into place,
so that the notches in the bottom of the plate slip over the power cables, and
the holes in the middle of the plate align with the screws in the tops of the
standoffs.
5. Tighten the two screws into the standoffs to secure the plate and the power
supply cables to the unit. Check to make certain that the cables are held firmly
in place by the cable keepers.
• MPC-16H-1 and MPC-16H-2: Sixteen-plug, horizontal units include pre-installed
cable keepers. When attaching the power supply cables to the unit, first swing the
cable keepers out of the way, then plug the power cables securely into the power
inputs. When the cables are in place, snap the cable keepers over each plug to
secure the cables to the unit.
