12 Function
12.1 Input
The maximum permissible current depends on the cross sec-
tion of the connected cables and the ambient temperature.
Only one redundancy module is required for decoupling two
power supply units1 and 2 switched in parallel with nominal
currents of up to 20A.
One redundancy module per power supply is required to de-
couple power supplies with nominal currents from 20 A to 40
A. Inputs 1 and 2 on the redundancy module must be con-
nected to the power supply unit using two conductors. This is
necessary because the maximum current carrying capacity of
30 A per input must not be exceeded. To connect the redun-
dancy module to the power supply unit, we recommend using
two conductors of the same length and with an identical cross
section.
12.2 Output
Only devices suitable for operation in the potentially explosive
areas of zone 2 may be connected to the output of the redun-
dancy module in zone 2.
Wire the load with the plus and minus terminals to the output
of the redundancy module.
