1.3 Supply voltage
On the back of the device there is a slot for a power supply unit (AC or DC)
and 2 inputs for the redundant power supply via the M4-POWER power
supply unit basic device. Both inputs are uncoupled.
Figure 1: Back side of the MACH4002 basic device
1 - M4-POWER connection (voltage input P3-1/P3-2, external)
2 - M4-POWER connection (voltage input P4-1/P4-2, external)
3 - Slot for slide-in power supply unit
(voltage input P1 and, if required, P2)
With redundant supply, the power supply unit with the higher output voltage
supplies the device on its own. The supply voltage is electrically isolated from
the housing.
With non-redundant supply of the mains voltage, the device reports a power
failure. You can avoid this message by changing the configuration in the
management, or, with power supply units of the same type, by feeding the
supply voltage in through both inputs.
