ZP40/60 Installation Manual
Adjusting output voltage beyond the set value stated may cause overvoltage protection (OVP) to operate, whereby
the output will latch off. To reset for normal operation simply adjust the potentiometer to reduce the output voltage to
within its range and cycle the input off then on.
All outputs are SELV except under the following circumstance: Outputs connected in series are non-SELV if the total
output voltage exceeds 60Vdc
If the total voltage of outputs connected in series exceed the 60Vdc SELV limit then all outputs must be considered
non-SELV.
Non-SELV outputs are hazardous and must not be made user accessible. Consideration must be given to service
engineers making inadvertent contact with the output terminals in the end equipment.
Cooling for unit
