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.
Operation in short-circuit protected network at max. 8 A.
■
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 drives,
■
and contactors, always use suitable EMC cables and layouts.
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
–
Male connector connection: Pin assignment
–
Cable connection: Wire color
Only apply voltage and switch on the voltage supply once all electrical connections have
been established.
NOTICE
Do not connect/remove the electrical connection when the sensor is operating. Switch
off the sensor before every use.
