Modular cable ARC-CC
Figure: Modular cable ARC-CC
The I/O and master units are to be connected to each other using a modular cable approved
by the manufacturer. The cable is equipped with quick- disconnect connectors.
Modular cables are available in lengths of 0.5, 1, 2, 3, 5, 7, 10, 15, and 20 metres.
NOTE! The total length of the modular or instrumentation cables of the system, measured from the
master unit to the furthest I/O unit, may not exceed 100 metres.
1.2. Operational safety
Dangerous voltages may occur at the terminal in the back panel of the master unit, even
though the auxiliary power supply has been disconnected. Do not open the secondary circuit
of a live current transformer. Disconnecting the secondary circuit of a live current transformer
may cause dangerous overcurrents! Always observe all national and regional regulations and
guidelines.
Read any instructions carefully before performing any operations.
