Notes on Operation

8.1 Inrush Current

If several products are connected in parallel and supplied on the input side using the
same circuit, higher inrush currents can result. In this case, the use of auxiliary relays,
which cause a time delay in startup, is recommended.
The maximum number of products that can be operated in parallel on one circuit is given
by the sum of the leakage currents. According to EN 62368-1, this sun must not exceed
the maximum value of 3.5 mA.
The maximum number of products that can be switched on at the same time depends,
among other things, on the backup fuse used and the impedance of the supply network.

8.2 Derating

The maximum load is dependent on the surrounding air temperature and the input volt-
age.

8.3 Parallel Connection

In parallel operation, set the output voltage of the products that will be connected in paral-
lel to precisely the same value, if possible. The resistance of the conductors between the
product and the load must be nearly identical. Only connect products of the same type in
parallel.
Use external rail-mount terminal blocks when connecting in parallel. A parallel connection
directly on the connectors on the secondary side of the product is not allowed.
