Mounting Guidelines to Reduce Electrical Noise
When mounting an AC line (EMC) filter or external shunt resistor refer
to the sections below for guidelines designed to reduce system
failures caused by excessive electrical noise.
AC Line Filters
Observe the following guidelines when mounting your AC line (EMC)
filter (refer to Figure 1.7 for an example).
• Mount the AC line filter and bonded cabinet ground bus on the
same panel as the Ultra3000, and as close to the Ultra3000 as
possible.
• Good HF bonding to the panel is critical. For painted panels, refer
to Figure 1.5.
• Segregate input and output wiring as far as possible.

ATTENTION
!
High voltage exists in AC line filters. The filter must
be grounded properly before applying power. Filter
capacitors retain high voltages after power removal.
Before handling the equipment, voltages should be
measured to determine safe levels. Failure to observe
this precaution could result in personal injury.
IMPORTANT
CE test certification applies only to AC line filter and
single drive. Multiple drive loads may perform
satisfactorily, but the user takes legal responsibility.
