Operating Instructions
Transponder-Coded Safety Switch CTP-LBI-AP
EN
10.2. Safety in case of faults
Ì
The operating voltage UB and the control voltage IMP are reverse polarity protected.
Ì
The safety outputs FO1A/FO1B are short circuit-proof.
Ì
A short circuit between FO1A and FO1B is detected by the switch.
Ì
A short circuit in the cable can be excluded by laying the cable with protection.
10.3. Fuse protection for power supply
The power supply must be provided with fuse protection depending on the number of switches and current required for the
outputs. The following rules apply:

10.4. Requirements for connection cables
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection cables.
Ì
Use connection components and connection cables from EUCHNER
Ì
On the usage of other connection components, the requirements in the following table apply.
EUCHNER provides no warranty for safe function in case of failure to comply with these require-
ments.
Observe the following requirements with respect to the connection cables:
