The following fusing is also possible for the digital output:
● In areas subject to the NEC or CEC, the fuse must meet the following requirements:
– Suitable for DC (min. 60 V / max. 1 A)
– Breaking current > highest possible current of the current source (incl. short circuit
current and fault)
– Approval according to UL 1077 or CSA C22.2 No. 235
● In other areas, the fuse must meet the following requirements:
– Suitable for DC (min. 60 V / max. 1 A)
– Breaking current > highest possible current of the current source (incl. short circuit
current and fault)
– Approval according to IEC/EN 60934

Order of the work
Connection only with power off
Only connect the device with the power switched off.
The device can be disconnected from the power supply with the terminal block.
Requirement: The device is mounted.
1. Connect the external power supply to the terminal block of the device.
Use functional earthing (see below) to ground the gateway.
2. Connect the cables of the two Ethernet networks to the interfaces of the device.
See the note in section Ethernet interfaces P1/P2 (Page 25).
3. CC716:
Connect the gateway on the RS485 socket to PROFIBUS via a plug-in cable.
Contacting the shield of the cable on the connector
The shield of the cable must be contacted. To do this, strip the insulation from the end of
the cable and connect the shield to functional earth.
