2
Valid for -7 versions without option E. This is the nominal value at 25
°
C and applies to cold models at initial switch-on cycle. Subsequent
switch-on/off cycles increase the inrush current peak value.

AC operating frequency range is 47 to 440 Hz (440 Hz for 115 V mains). For frequencies
≥
63 Hz refer to
Safety and Installation Instructions
.
Input Transient Protection
A suppressor diode and/or a VDR (depending on input voltage
range) together with the input fuse and a symmetrical input filter
form an effective protection against high input transient voltages
which typically occur in most installations, but especially in
battery-driven mobile applications.
Nominal battery voltages in use are: 12, 24, 36, 48, 60, 72, 110,
and 220 V. In most cases each nominal value is specified in a
tolerance of –30% to 25%.
In certain applications, surges according to RIA 12 are
specified in addition to those defined in IEC 60571-1. The
power supply must not switch off during these surges and
since their energy can practically not be absorbed an
extremely wide input range is required. The EK input range
for 110 V batteries has been designed and tested to meet
this requirement.
