Mounting and connection
The cables are connected to the device via push-in terminals. The maximum permissible conduc-
tor cross section is 1.5 mm².

Short circuit.
When finely stranded cables are inserted directly into the push-in termi-
nals, spliced wires can cause a short circuit. Use ferrules.
The terminals only allow the use of ferrules from 0.25 mm² to 1.5 mm². The maximum cross sec-
tion of 1.5 mm² should under no circumstances be exceeded!
Use crimping pliers which
1. do not exceed the permitted crimp width of the ferrule and
2. do not leave strong crimp impressions on the ferrule.
i
For a cross section of 1 mm² or more, use suitable crimping pliers similar to the models
"CRIMPFOX 6", "Weidmüller PZ6" or "Weidmüller PZ6/5".

iso415R-24
The iso415R-24 is supplied with DC 24 V via the
+ and - terminals. The DC 24 V source must not
have a connection to earth.
i
No other devices that have a connection
to earth may be supplied from this volt-
age source. (e.g. additional iso415R devic-
es)
iso415R-2
The iso415R-2 is supplied from the system to
be monitored via terminals L1 and L2. The per-
missible voltage is in the range of AC/DC
100...240 V.
i
The device must be provided with back-
up fuses ( 2 A) in both terminals.
