2 analog outputs (AO)
Power supply unit, 24 V, 300 mA
In addition to the main board, the peripheral boards two and four are also fitted with a
daughterboard which contains the circuitry for the PTC thermistor inputs.
The connection diagram of these variants can be found in the section "Control cable terminals
"peripheral board 1" (Page 120).
Use the digital inputs and the analog outputs of the peripheral board corresponding to the
inputs and outputs on the main terminal block. Further information can be found in the section
"Standard control cable terminals" (Page 119).
Configure the three relay outputs corresponding to the relay outputs of the main terminal block.
For further information about galvanic isolation, refer to section "Safe isolation in accordance
with EN 61800-5-1" (Page 97).

10.2.2.2

General information about electronic shutdown

Using the electronic shutdown concept of the inverter, a system without main contactor can
be shut down. This also applies for the operation of motors in the Ex-Zone 1. In the case of a
fault, the inverter interrupts the power supply to the motor electronically.
10.2.2.3

Motor temperature monitoring shutdown concept

Principle of operation
The peripheral board 2 / 4 evaluates the measure motor temperature using a PTC thermistor.
The board ensures safety and reliability using the installed short-circuit detection. The "Safe
