6.12.3
Connecting circuit breakers
To connect the circuit breaker, proceed as follows:
1. Disconnect the cabinet from the power supply.
2. Route the control cables into the cabinet from below.
3. Connect the shields of the control cables to the serrated bar. For additional information, see
Chapter "Using the equipotential bonding strip and shield bus (Page 89)".
4. Connect the control cables as specified in the circuit manual.
6.12.4
Connecting the encoder
Procedure
NOTICE
Damage caused by incorrectly connected external encoder
Components can be damaged if the external encoder is not connected or operated correctly.
• Only one measuring system can be connected to each sensor module. The sensor module
is wired internally to the customer terminal strip. For further information, see the circuit
manual.
To connect the encoder, proceed as follows:
1. The five safety rules must be observed.
2. Route the cables from the encoder into the cabinet from below and to the customer terminal
strips.
3. Connect the signal line to the customer terminal strip. You will find details of this in the circuit
manual.
4. Connect the shield of the encoder cable directly to the shielding bus (serrated bar). It is
important here to establish the greatest possible area of contact and a good conductive
connection. Use metal ground clamps to secure the shield in place.
