8.3 External power connection
The instrument must have the S4N-PWR3 or S4N-PWR4 module in the SLOT4 position,
depending on the type and size of the supply voltage. The device is delivered with a fitted power
supply module according to the customer's requirements and without a power supply.
NOTICE
In the case of a corrector powered from the 230 V mains, there is a risk of
death if the conductive parts are touched!
For this reason:
 Work on the electrical components of the device and connection of the
mains supply of the device must be carried out by a worker with the
