Work to be done
▸
Connect the connection line:
see “Standard connection”, page 50
.
▸
Connect lines for status signals (operation/failure, maintenance, function check, main-
tenance request, limit value), analog output, analog and digital inputs according to
requirements (
see “Standard connection”, page 50

Terminals for power connection
If an onsite line is to be used, it must be connected to a suitable 7-pole socket (
“Plug connector connection to onsite line”, page 49
; SICK Part No.: 7045569).
NOTICE:
▸
Only use shielded lines with twisted pairs (e.g., UNITRONIC LiYCY (TP) 2 x
2 x 0.5 mm² from LAPPKabel; 1 pair of wires for RS 485, 1 pair of wires
for power supply; not suitable for underground laying).
WARNING:
▸
Be sure to check the wiring before switching the supply voltage on.
▸
Only modify wiring when disconnected from the power supply and potential-
free.
