Power supply
The side of the housing of the OIT system has an 8-pin Harting HAN Q 8/0 F
connector for the power supply. The pin assignments are shown in the following
illustration:

Power supply connection layout
Mode bit 0 and mode bit 1 are digital inputs.
Galvanic isolation
There is no galvanic isolation between the supply line and the signal line in the
factory settings. Both switches are positioned to the right in the factory presets. To
galvanically isolate, both switches must be positioned to the left. After that, Pin2
and Pin5 must be powered by a different power supply than the OIT.

Note!
Resetting the Parameterization Lock
You can reset the activated parameterization lock by applying a logical high to the
pin 3 mode bit 1 (MOD 1) and a simultaneous logical low to the pin 4 mode bit 0
(MOD 0). After applying this logic level to the inputs, the locking bit in the
parameter byte can be reset to "0".
