6.5 Earthing and functional earth
In order to maintain conformity with the EMC limit values and ensure the functioning
of the drive amplifier, the housing of the drive amplifier must be connected to the control
cabinet's functional earth with low impedance.
When mounting the drive amplifier on a metallic and conductive top-hat rail it must
be ensured that the top-hat rail is connected to the control cabinet's functional ground
with sufficiently low impedance.

If the drive amplifier is not sufficiently grounded, this may cause
radio interference, leading to non-conformity with the EC EMC
Directive. This can result in malfunctions in the drive amplifier and
other electronic systems.
6.5.1 X1: Power supply
The safety input STO (pin 3+5) is galvanically isolated from the intermediate circuit voltage (pin
A) and the logic power supply (pin 1). UZK or GND (pin B) is not connected with the functional
earth and the housing within the device.

must be used. Lower resistance
values must not be connected, a higher current could destroy the chopper control. Larger resistance
values can be used, thus reducing the chopper peak power accordingly.
