OCM F Power Supply
Depending on the type of OCM F used, it can be supplied, with 85-260 V AC.
Also possible is a 24 V DC supply. The two slide switches located above the
terminals serve as additional power switch.

A transmitter with 24 V DC cannot be operated with alternating current, just as
it is impossible to operate a 230 V AC transmitter with direct current.
When operated with alternating current, the direct current supply clamps 4 and 5
both provide a voltage of 24 V and max. capacity of 100 mA (turn on 24 V
switch!). Please note, when using this supply voltage (e.g. for digital inputs with
control signals), it must not be shielded through the complete switchgear in order
to maintain disturbing interferences on a low level.
