The DIN rail connector is integrated into the DIN rail. The bus connector
has 5 positions for energy supply and data transmission. It connects
several zener barrier modules, which are mounted on the DIN rail.

Equipment Operation
The barrier should be connected into the circuit while it is unpowered.
The voltage through the barrier under normal operation should not
exceed the rated Uo voltage. DC voltages and AC voltages of up to 1 MHz
pass through the barrier without attenuation. Any voltage above the
rated voltage is clamped to the rated voltage until the current exceeds
40 mA at which time an internal fuse is blown. Resistors are included in
the device to limit the available current in the Hazardous area. The
device protects the Hazardous area from high voltages and currents
which may cause sparks. The barrier must be connected using the proper
wires, wire gauge and codes as shown in the drawing on chapter
"Electrical wiring drawings" & "Electrical/Electromechanical drawings" .
