When using a dual AC power & cables take this step:
Attach one end of each of the supplied 100/240 VAC power cables to the rear AC sockets and
connect each of the other ends to separate earthed mains circuits (for power source redundancy).

Connecting the DC Power Supply
To connect the MG 3200 to a DC power supply use one of these two options:
•
DC Terminal block with a screw connection type.
•
DC Terminal block with a crimp connection type.
When using a DC terminal block screw connector, take these 3 steps:
1.
Create a DC cable by inserting two 14-16 AWG insulated wires into the supplied adaptor
(refer to
2.
Connect the two insulated wires to the correct DC power supply. Ensure that the connections
to the DC power supply maintain the correct polarity.
3.
Insert the terminal block into the DC inlet located on the MG 3200.
When using a DC terminal block crimp connector, take these 3 steps:
1.
Remove the DC adaptor (screw connection type) that is attached to the MG 3200 rear panel.
2.
Connect the two insulated wires to the correct DC power supply. Ensure that the connections
to the DC power supply maintain the correct polarity (refer to
3.
Insert the terminal block to the DC inlet located on the MG 3200.

unconnected) the chassis' LED (on the left side) is lit Red, indicating that one of the
dual power inlets is disconnected.
When both the AC power cables are connected, one of the plugs can be
disconnected under power without affecting operation, in which case the chassis'
left LED is lit Red.
UPS can be connected to either (or both) of the AC connections.
The dual AC connections operate in a 1 + 1 configuration and provide load-sharing
redundancy.
Each of the dual power cables can be connected to different power phases.
