Mounting Guidelines to Reduce Electrical Noise
When mounting an AC line (EMC) filter, external shunt resistor, or
wiring the motor brake and thermal switch, 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 on the same panel as the 1394 along the
right side of the right-most axis module.
•
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.
IMPORTANT
CE test certification applies only to AC line filter and
single 1394 drive. Multiple drive loads may perform
satisfactorily, but the user takes legal responsibility.
