Wiring the redundant power input

The DVW-W01I2-E1 is equipped with one to two sets of DC input (PWR1 / PWR2). Both sets of DC input can
be connected to a wide range of power sources (12 to 48VDC). When one power source fails, the other
source can work as a backup to ensure that the machine operates normally.

Step 1: Detach the terminal block from DVW-W01I2-E1 and insert the negative and positive DC wires into the
terminal block. Make sure that the positive DC wire is connected to V1+ or V2+, and that the negative DC wire
is connected to 0V.
Step 2: To prevent the loose DC wires, tighten the wire clamp screws on the terminal block with the flat-blade
screwdriver.
Note: Please use copper wire 60/75
1.3.4 Wiring the alarm contact
The DVW-W01I2-E1 is equipped with one to two sets of alarm output. The alarm contact is a dry relay. Under
normal mode of operation, the contact is in "OPEN" circuit; when one of the two power sources fails or
communication is interrupted, the contact will change to a "CLOSED" circuit. The relay can be connected up
to 1A/24VDC power source.
