RFI Grounding
The iQ Series generator provides the operating power
and power returns. Make sure the generator is grounded
properly.
In addition to the safety considerations, proper grounding
is essential for the effective suppression of RFI (Radio
Frequency Interference). Every generator contains a
RFI filter which blocks noise on the AC power line from
entering the generator control circuitry. This filter also
prevents ultrasonic RFI from being fed back into the AC
power line.
If you experience problems with RFI from the press, run
an additional grounding wire from the press base ground-
ing stud to the nearest grounded metal pipe or equivalent
earth ground by means of a ground clamp. Use at least 14
AWG wire for the connection to the press base.
CAUTION
To minimize electrical noise
and eliminate ground cur-
rents, ground the chassis
as shown. Use a STAR con-
figuration (illustrated below).
Do not DAISY CHAIN the
grounds.
