Installation
Installation must strictly follow the national safety regula-
tions. Pin 24 has to be connected to earth. A second fuse
should be installed in the wiring to pins 26/28 if:
– Local requirements demand an individual fuse in each
source line
– Neutral to protective earth impedance is high or unde-
fined
– Phase and neutral of the mains are not defined.
In applications where the inhibit function is not used, the
inhibit pin should be connected to the S– pin (S 1000) or
the Vo1– pin (S 2000) to enable the outputs.
Important Advice
Electric strength tests should not be repeated in the field.
Improper test methods, for example overshooting or os-
cillating test voltages, voltage slopes exceeding 1 kV/
s,
internal Y-capacitors not carefully discharged, etc. can
cause severe damage to switching devices and ICs.
Melcher will not honour any guarantee/warranty claims
resulting from high voltage field tests.
