Terminal block for supply voltage and signal contact
The supply voltage and the signal contact are connected via a 6-pin terminal
block with a snap lock.
Supply voltage
Redundant power supplies can be used. Both inputs are uncoupled.
There is no distributed load. With redundant supply, the power supply unit
supplies the device only with the higher output voltage. The supply
voltage is electrically isolated from the housing.
You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24 V and 0 V pins to connect the AC voltage (
fig. 6
and
fig. 7
).
Note:
With non-redundant supply of the main voltage, the device reports
a loss of power. You can avert this message by applying the supply
voltage via both inputs, or by changing the configuration in the
Management.

DANGER
HAZARD OF ELECTRIC SHOCK OR BURN
When the module is operated with direct plug-in power units, use only:
– SELV supply units that comply with IEC 60950/EN 60950 and
– (in USA and Canada) Class 2 power units that comply with applicable
national or regional electrical codes
Connect the ground wire to the PE terminal (where applicable) before you
establish any further connections. When you remove connections,
disconnect the ground wire last.
Failure to follow these instructions will result in death, serious injury,
or equipment damage
