￭ Connection procedure of the thermal switch cable
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death, or
damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
1. Stop the drive and do the steps in section Electrical safety precautions (page 50) before
you start the work.
2. Run the sensor cable inside the brake unit cubicle.
3. ABB recommends that you ground the cable shield 360° at the cable entry.
4. Run the cable to its connection point using existing trunking wherever possible. Protect
the cables against any sharp edges or hot surfaces.
5. Connect the conductors to the appropriate terminals.
6. Twist the cable shield into a bundle, crimp a ring terminal onto it and connect it to the
nearest chassis grounding point. At the other end of the cable, leave the shields
unconnected or ground them via a capacitor (eg. 3.3 nF / 630 V).
Connecting the fiber optic cables
Connect the fiber optic cables to the brake modules.
Installing optional modules
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur.
Note: Pay attention to the free space required by the cabling or terminals coming to the
optional modules.
1. Repeat the steps described in section Electrical safety precautions (page 50) .
2. Ensure by measuring that the I/O terminals of the control unit (especially the relay output
terminals) are safe.
3. Insert the module into a free option module slot on the control unit.
4. Fasten the module. For instructions, see the documentation of the optional module.
5. Connect the necessary wiring to the module following the instructions given in the
documentation of the module.
6. Tighten the grounding screw to a torque of 0.8 N·m (7 lbf·in).
Note: The screw tightens the connections and grounds the module. It is essential for
fulfilling the EMC requirements and for proper operation of the module.
