During type test only, with all protective impedances removed
The device uses the principle of protective impedance for the voltage inputs
to ensure protection against electric shock. All circuits of the device are
tested during final inspection.
Prior to performing high voltage or isolation tests involving the voltage
inputs, all output connections of the device, especially analog outputs, digital
and relay outputs as well as Modbus and Ethernet interface, must be
removed. A possible high-voltage test between input and output circuits must
be limited to 500V DC, otherwise electronic components can be damaged.
