Unpacking
Carefully open your shipping container, and make sure
it contains the items shown on the shipping documents.
Inspect all items, and report any missing items or damage
immediately.
Placing
Make certain generator placement and cable routing do
not interfere with normal operation. Maintain easy access
to your equipment.
The operator should have unobstructed access to cables
and wiring.
RFI Grounding
Proper grounding for the generator chassis is essential
for the effective suppression of electrical noise or
RFI (Radio Frequency Interference). Every ultrasonic
generator contains a RFI lter that blocks noise on the
AC power line from entering the system control circuitry.
This lter also prevents ultrasonic frequency noise from
being fed back into the AC power line. For the RFI lter
to operate effectively, it is necessary to correctly ground
the system.
Connect a grounding wire from the grounding stud
connection (see Figure 3-1) to the nearest grounded metal
pipe or equivalent earth ground.
See Connecting Cables on the next page.
CAUTION
To m i n i m i z e e l e c t r i -
cal noise and eliminate
ground currents, ground
the chassis as shown.
Use a STAR conguration
(illustrated below). Do not
DAISY CHAIN the grounds.

NOTE
Chassis Grounding Stud
The chassis grounding stud is used to
attach a protective earth ground to the
generator. This will aid in the suppression
of electrical interference or radio frequency
interference (RFI) that is common in a
industrial environment. Stud location
is shown in Figure 3-1 on the following
page.
CAUTION
If you have any questions
about the grounding of your
equipment and/or the electri-
cal box, contact a qualified
electrician.
