Connecting to the Power Source
To connect to the AC Inlet:
1.
Make sure that the power switch located on the rear panel of the MGC
unit is off.
2.
Insert the power cable into the power connector on the rear panel of the
MGC-50 unit.
3.
Insert the power cable into the power source socket.
4.
Turn on the power by pressing on the power switch located on the rear
panel of the MGC-50 unit.
If the unit is rack mounted, the single-point ground on the MCU-50 must
be connected to the rack with a single conductor and attached so that it
prevents loosening.
The following restrictions apply to the conductors and connectors that
may be used to ground the unit when rack mounted:
—
When using bare conductors, they must be coated with an
appropriate antioxidant compound before crimp connections are
made. Tinned, solder-plated or silver plated connectors do not have
to be prepared in this manner.
—
Multiple connectors should not be secured with the same bolt
assemblies.
—
Listed fastening hardware must be compatible with the materials
being joined and must avoid loosening, deterioration and
electrochemical corrosion of the hardware and joint materials.
