Warning
Switch off the power supply before
installing!
Enclosure class IP65 is only
guaranteed with the front panel of the
terminals enclosure closed and with
appropriate cable glands or dummy
caps.
Warning
Switch off the power supply before
connecting the power supply cable and
the relay contacts! For safety reasons,
the protective conductor must be
connected correctly!
Observe the local safety regulations!
Protect the cable connections and
plugs against corrosion and humidity.
Before connecting the power supply
cable, check that the supply voltage
specified on the nameplate
corresponds to the local conditions!
An incorrect supply voltage may
destroy the device!
To guarantee electromagnetic
Caution compatibility (EMC), the input and
current output cables must be
screened.
Connect the screening to the screen
ground on one side.
Refer to the wiring diagram! Route the
input, current output and power supply
cables in separate cable channels.
Enclosure class IP65 is only
guaranteed if the terminal cover is
correctly sealed! Do not damage the
Caution gasket on the terminal cover!
The gasket on the terminal cover must
be positioned precisely!
Do not damage the gasket!
Note Unused terminals must remain open.
1. Remove the terminal cover on the front of the
device.
2. Use the appropriate cable feedthroughs and
tighten the screws carefully.
3. Connect the cables used to the terminals
according to the Conex® DIA-2Q terminal
assignment.
4. Close the terminal cover again with correctly
positioned gasket.
