2.2.3 Connecting the signal contact
Relevant for North America:
The torque for tightening the terminal block for the signal contact on the
device is 3 lb-in (0.34 Nm).
Note: Use copper wire with cross-section AWG 20 to AWG 12 (0.5 mm
2
to
3.0 mm
2
) and stripping length12 mm.
For every signal contact to be connected, make sure the following
requirements are met:
 The electrical wires are voltage-free.
 The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
For every signal contact to be connected, perform the following steps:
 For plugged connections: connect the signal contact lines with the
terminal block connections. Mount the terminal block on the device using
screws.
 To insert the cable, you open the terminal lock by positioning the
screwdriver as illustrated below and pressing on the lever.
 For terminal connections: connect the signal contact lines to the
connection terminals.
