# Connecting Power Supply

The DMA-EZCCM-001 module is provided with two 4-pin M8 plug connectors for connecting the power supply. V1 and V2 are galvanically isolated.

CAUTION:

Observe using the correct M8-connectors when connecting Ethernet and power cables (Ethernet: P1 and P2, power: X1 and X2). Interchanging the Ethernet and the power cables can destruct the internal electronics.

Connect the device to the voltage supply according to the pin assignment below.

X1 | Power feed
X2 | Continuation of the power to the next node
V1 | Power Supply 1 (including supply of electronics)
V2 | Power supply 2

Note: The system voltage (V1) and the load voltage (V2) are fed in and monitored separately. In case of an undercut of the admissible voltage, the connectors are switched off according to the module's supply concept. In case of an undervoltage at V2, the LED PWR changes from green to red. In case of an undervoltage at V1, the led is turned off.
