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.
