local energy supply companies must be adhered to.
7.1
Installation
The installation of the CIF modules is described in the installation and operating in-
structions of the product into which the CIF module is to be installed.
To ensure interference resistance in industrial environments (EN 61000-6-2), the
data cables must be shielded cables and they must be used with an EMC-compliant
cable gland (included with the module).
The screen must be earthed at both ends.
For optimal transmission with BACnet MS/TP, CANopen or Modbus RTU, the data
cable pair must be twisted and have a surge impedance of 120 Ω.
DANGER
Risk of fatal electrical shock!
Before all work deactivate power supply and guard against accidental switch-on.
Work on the control module may only be started after 5 minutes have elapsed,
due to the dangerous residual contact voltage.
Check whether all connections (including potential-free contacts) are voltage-
free.
