The relay is designed for DIN rail mounting. The environmental conditions from the section
2.1 must be observed. For the dimension drawing see Appendix. A
3.1 Mounting
 Align the upper slide of the DIN rail
mounting groove with the DIN rail and
push it onto the rail.
 Wire external connections in
accordance with sec. 3.2 using plug-in

3.2 Wiring
WARNING
Electric shock could kill or seriously injure.
All electrical connections must be performed by a fully qualified electrician.
Ensure that the mains voltage matches the voltage marked on the nameplate.
Ensure that the device is provided with its own power supply line and electric fuse.
Do not feed any external devices from the power contacts of the device.
Remove the terminal blocks only after powering off the device and all connected
equipment.
WARNING
The device must be powered off before connecting to peripheral devices, internal
bus or PC. Switch on the power supply only after the wiring of the device has been
completed.
WARNING
The program runs after transferring it to the relay. It is recommended to transfer the
program before wiring the relay.
Otherwise ensure that all peripheral devices are disconnected from relay outputs
before transferring the program.
NOTICE
Supply voltage for 24 VDC models may not exceed 30 V. Higher voltage can damage
the device.
If the supply voltage is lower than 19 V DC, the device cannot operate properly but
will not be damaged.
NOTICE
Signal cables should be routed separately or screened from the supply cables.
Shielded cable should be used for the signal lines to ensure compliance with the
EMC requirements.
NOTE
Before powering on, make sure that the device was stored at the specified ambient
temperature (-20 ... +55 °C) for at least 30 minutes.
