Remote expansion
Remote expansion units can be installed and run up to 30 m
away from the basic unit.
j
Warning!
The following electrical separation is implemented
between the CL-LMR.C.../CL-LMT.C... basic unit and the
expansion device (separation always in local connection of
expansion unit)
• Basic isolation 400 V AC (+10 %)
• Safe isolation 240 V AC (+10 %)
Units may be destroyed if the value 400 V AC +10 % is
exceeded, and may cause the malfunction of the entire
system or machine!
h
The basic unit and expansion unit can be provided with
different DC power supplies.
j
Warning!
The two-wire or multi-core cable between units must have
the necessary insulation voltage required for the
installation environment concerned. In the event of a fault
(ground leakage, short-circuit) serious damage or injury to
persons may otherwise occur.
A cable such as NYM-0 with a rated operating voltage of
U
e
= 300/500 V AC is normally sufficient.
