Each D20E module requires 5W of power using an external 24/48 VDC power supply.
Figure 16 shows the location of the redundant power supply connections.
Figure 16: D20E redundant power supply connections
The wiring connected to terminal block TB1 must not have exposed accessible
conductors.
The wire and cable connected must have at least a +80
Ensure that the external power source is shut off before connecting or disconnecting
the power supply to the D20E Ethernet I/O Module. Use an approved external 20A
switch or circuit breaker that opens all conductors simultaneously. The switch or
circuit breaker must be suitably located, easily reached, and labeled appropriately.
