Mechanical installation
Refer to Installing options (page 86) and BAPO, BREL, BRES, and BTAC modules
quick installation guide (3AXD50000837946 [English]).
Electrical installation
Use 0.5 … 2.5 mm
2
(20 … 14 AWG) cable with a sufficient voltage rating.
If you connect an inductive load (relay or contactor coil, motor) protect the relay
contacts with a varistor, RC filter (AC) or diode (DC). Install the protective
component as close to the inductive load as possible. Do not install protective
components at the relay output terminals.
