The relay contact and the ON/OFF signal input are floating and have no ohmic connection to the input or output
voltage. Type and factory tests are conducted by the manufacturer.
The creepage and clearance distances between relay contacts, the ON/OFF signal input and input/output voltage are
1.3mm.
The following dielectric strength tests were conducted:

Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the
appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input and
output terminals together as well as all signal poles before conducting the tests. When testing, set the cut-off current
settings to the value in the table above.
