Setting the CAN Bus Address via Thumb Wheel Switch S2

DANGER

Warning of dangerous electrical voltage! Danger to life - Danger of electric shock! BEFORE

connecting and disconnecting, it must be ensured that

no voltage

is present at all connections of the

controller.



ATTENTION

All CAN bus supply cables must be shielded (cable type

LiYCY 2x2x0.75 mm

)! As a general rule,

care should be taken to ensure that signal cables and cables carrying mains voltage are routed in
separate cable ducts. Maximum length of the cable: 500 m.

Wiring variant A

: Unit is a device in a CAN bus segment with other devices before and after this,

terminating resistor

required.

Wiring variant B

: Unit is at the beginning / end of a CAN bus segment,

a terminating resistor 100

Ohm is required

(item number KGLCANTERM).

For further details on the CAN bus, see the operating instructions
