Powerinput(3pinterminalblock)
The redundant power unit models have two terminal blocks for P1 and P2 power input. MAR1040
family is powered by the terminal block regardless of DC or AC.
The pin function is as shown below.

For more information about wiring to the terminal block, see section 2.4.2.
AC power cable is not included in the MAR1040 family.
Please prepare AC power cable allowed to be used in the local regions.
For redundant power unit model, use both P1 and P2 power inputs unless otherwise the power
fail alarm will be detected on this device.
FAULToutput
FAULT output 1 and 2 have two contact pins respectively.
Each FAULT output becomes open when the device status error is detected based on the
conditions configured for each output. For FAULT output 1, the device status error is triggered by
power failure by the default configuration. For FAULT output 2, the device status error condition is
not defined by the default configuration.
For more information about wiring to the terminal block, see section 2.4.2.
