Installation Instructions
Installation of the power supply must strictly follow the na-
tional safety regulations. To observe the safety require-
ments according to EN 60950/IEC 950, the module shall be
connected via the female connector type H11 (see section
"Accessories"). Other installation methods may not meet
the safety requirements. A second fuse should be installed
in the wiring to pin 29 if:
– Local requirements demand an individual fuse in each
source line
– Input to earth impedance is high or undefined
– Phase and neutral of the mains are not defined (AC-DC
converters)
Reverse polarity at the input of A...D/FM and C/DMZ types
will cause the fuse to blow. In E/LM and LMZ types a series
diode will protect the module. A series diode is not incorpo-
rated in A...D/FM and C/DMZ types to avoid unwanted
power loss.
Whenever the inhibit function is not required, pin 2 (i)
should be connected to pin 23 to enable the output(s).
