with screw terminals (M3). The control wires for the aux-
iliary switches must be stripped accordingly (if neces-
sary, use appropriate wire end sleeves).
NOTICE
X The maximum permissible conductor crosssec-
tion of the auxiliary switches control wires is
1mm
2
/ AWG 18 stranded wire.
X Mechanically secure the control wires to mini-
mise feedback eects of forces caused by the
wires (e. g. shock, vibrations) acting on the ter-
minals.
X Route the control wires (2) to the terminals of the
auxiliary switches (1).
X Connect the control wires to the screw terminals
of the auxiliary switches (1).
- For the a1 and b0 contacts (auxiliary switches
S870) no polarity must be observed.
- For the general purpose contacts (auxiliary
switches S826) the polarity must be observed).
X Tighten the terminal screws to the prescribed
torque:
- With S870 auxiliary switches: 0.7 - 0.9 Nm
- With S826 auxiliary switches: 0.7 - 0.9 Nm
X Check the routing of the wiring. Wires must not be
