The connection must be made as follows:
1.
The cross-section of the power supply cable must be at least 0.75 mm²
and a maximum of 2.5 mm².
2. A flexible lead or wire can be used for the connection.
3. The current consumption (
Î Section 11) must be taken into account
when implementing the power supply.
4. The functional earth is not compulsory for operation. But it can help to
avoid disturbance caused by potential differences.
5. The GND connection is directly connected to the housing potential
6. For safety reasons the wires should be fixed together near by the
connector
The plug connector (socket connector with screw terminals) is supplied with
the device for connection.
Connector assignment
In the event of reverse connection and simultaneous
connection of a further 0V connection, e.g. GND
connection of the COM1 interface, the fault current flows
via this OV connection. If the housing is not lying well set
on the OV potential, the result can be destruction of the
device or of the external components!
For safety reasons the wires should be fixed together
near by the connector.

UPS
The device includes a power fail functionality. The power fail mechanism
prevents the loss of retain data if a Soft-PLC (Codesys or AT-S7) is used.
The retain data are stored on CompactFlash when the PLC is shutting down
and are read out again when the PLC starts up. (for details s.a. System
description Codesys Soft-PLC or AT-S7)
The standard integrated UPS-solution can bridge brownouts up to about 5s.
