Improper installation
WARNING
Improper installation can cause serious or minor injuries and damage the de-
vice. Installation must be performed only by fully qualified personnel.
–
The module is designed for DIN rail mounting in a control cabinet or for wall mount-
ing.
–
The mounting enclosure must provide a clean, dry and controlled environment. For
further requirements refer to the subchapter 2.3.
–
The device has been designed for natural convection cooling. Make sure that the
cabinet provides sufficient clearance for natural convection.
4.1
Dangerous voltage
Electric shock could kill or seriously injure.
All electrical connections must be performed by a fully qualified electrician.
WARNING
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!
Switch on the power supply only after the wiring of the device has been com-

NOTICE
pletely performed.
–
Electrical connections are shown in Fig. 4.1 and pin assignments are shown in Table
4.1.
–
Connection variants for different signal types are shown in Fig. 4.2 – 4.4.
–
Connect power supply to the 24V / 0V terminals.
–
The maximum conductor cross-section for power supply is 1.5 mm
EMC-safety
Signal cables should be routed separately or screened from the supply cables.
►
NOTICE
Only shielded cable may be used for data transmission and signal lines.
Shield in the control cabinet for best electromagnetic immunity recommended.
–
Connect the RS485 line to the terminals D+ and D-.
–
Use twisted pair cable for RS485 connection. The length of the line should not ex-
ceed 1200 m.
4.1.1
The data in permanent memory may be lost because of strong electromagnetic interfer-
ences or similar conditions.
The jumper X1 (hardware write protection) makes it possible to avoid data loss.
The following steps are required:
–
Switch off the power supply
–
Open the cover on the front panel of the module (see Fig. 4.1)
–
Put the jumper X1 in the position "closed"
Thereby the following is to observe:
–
To change the configuration parameters, the jumper X1 must be removed again.
–
As long as jumper X1 is put, the input counter will be reset after any power loss.
4.1.2
To the input of type DN can be connected:
–
potential-free contacts
–
NPN transistor outputs with open collector
