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.
