2.3.2 Connection of the operating voltage
S Use an operating voltage cable with sufficient
cross-sectional area.
S Avoid long distances between the power supply unit and
the Checkbox. Long operating voltage cables reduce the
voltage supplied by the power unit.
S Protect the supply cable with a 5 A cut-out fuse with me-
dium time-lag.
Connect the Checkbox to the operating voltage as follows:
Pin
24 V DC plug
1 Do not connect
2 +24 V DC, +/- 15 %
with 5 A medium time-lag fuse
3 GND
4 Do not connect
Tab. 2/3: 24 V DC connection plug
Use only a 4-pin M18 socket for the power supply and
connect this only to the connection for the power supply.
1. Connect the plug to the 24 V DC connection on the
Checkbox.
2. Tighten the union nuts of the plug by hand.
