Specifications for ferrules

Recommended crimping
tool
Ferrules without insulating
collar, in accordance with
DIN 46228-1
3.2.4.2 Connecting the supply voltage
The device is operated using a 24 V DC voltage, which is applied via COMBICON connec-
tors. For the 22xx/23xx device versions, you can supply the voltage redundantly (see
Figure 37).
The module is designed exclusively for operation with safety extra-low voltage
(SELV/PELV). In redundant operation, both power supplies must satisfy the requirements
of the safety extra-low voltage.
For 22xx/23xx device versions:
If redundant power supply monitoring is active (default setting), an error is indicated if only
one voltage is applied.
A bridge between US1 and US2 prevents this error message. It is possible to deactivate
monitoring in web-based management or via SNMP.
