which typically occur in most installations, but especially in
battery driven mobile applications. The M series has been
successfully tested to the following specifications:
Electromagnetic Compatibility (EMC)
A suppressor diode or a metal oxide VDR (depending upon
the type) together with an input fuse and an input filter form
an effective protection against high input transient voltages
Electromagnetic Immunity

3 A = Normal operation, no deviation from specifications, B = Temporary deviation from specs possible.
4 Only met with extended input voltage range of BM (24 V battery), CM (48 V battery) and EM (110 V battery) types. These units are
available on customer's request. Standard DM units (110 V battery) will not be damaged, but overvoltage lock-out will occur during the
surge.
5 For converters with 3 output voltages, temporary deviation from specs possible.
6 With class II equipment (CMZ, DMZ, LMZ) only met if case is earthed.
