Type tests and factory tests:

Conducted by the manufacturer. Do not repeat test in field!

Rules for field test:

Use appropriate test equipment which applies the voltage

with a slow ramp! Connect L and N together as well as all

output poles.

The output voltage is floating and has no ohmic connection to ground.

To fulfill the PELV requirements according to EN60204-1 § 6.4.1, we recommend that either the + pole, the – pole or

any other part of the output circuit shall be connected to the protective earth system. This helps to avoid situations in

which a load starts unexpectedly or can not be switched off any more when unnoticed earth faults occur.
