Power Connectors.
An IMx-M rack has two power connectors available, AC1 for power supply unit 1 and
AC2 for power supply unit 2, one for each redundant power supply unit. Each power
supply unit is independently capable of supplying power for the entire monitor system
(IMx-M rack) including sensors.
The rack is grounded through the protective earth lead of the power cable. Therefore, it
is important to make sure that the earth terminal of the power cable is properly
connected to the protective earth lead before connecting any of the input or output
terminals of the rack.
Surge suppressors are connected between network terminals and protective earth.
Therefore, equipment must be connected to an earthed mains socket-outlet.
In order to attach the power cable to mains power, follow the directions below.
