NOTICE
Equipment damage or unpredictable operation due to working with live parts!
Working with live parts may result in unpredictable operation.
Only carry out wiring work when the power is off.
■
Only connect and disconnect electrical connections when the power is off.
■
The electrical installation must only be performed by electrically qualified person‐
■
nel.
Standard safety requirements must be observed when working on electrical
■
systems!
Only switch on the supply voltage for the device when the connection tasks have
■
been completed and the wiring has been thoroughly checked.
When using extension cables with open ends, ensure that bare wire ends do not
■
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be properly insulated from each other.
Wire cross-sections in the supply cable from the user's power system must be
■
selected in accordance with the applicable standards.
NOTE
Layout of data cables
Use shielded data cables with twisted-pair wires.
■
Implement proper and complete shielding concept.
■
To avoid interference, e.g., from switching power supplies, motors, clocked regula‐
■
tors, and contactors, always use cables and layouts that are suitable for EMC.
Do not lay cables over long distances in parallel with voltage supply cables and
■
motor cables in cable ducts.
The IP enclosure rating for the device is only achieved under the following conditions:
The cables plugged into the connections are screwed tight.
■
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!
The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
Operation in standard I/O mode:
– Plug connection: Pin assignment
– Wire: wire color
Do not apply and switch on the power supply until all electrical connections have been
made.
