HIGH VOLTAGE CABLE
According to OSHA standard 1910.107,(h)(5),
high voltage cable “shall be properly insulated and
protected from mechanical injury or exposure to
destructive chemicals”. It is extremely important
to route the high voltage cable according to the
following guidelines and to maintain the cables
properly. This is due to the fact that dielectric type
high voltage breakdowns of high voltage cables
CANNOT be detected in time to prevent an arc
from occurring. To facilitate compliance with this
code, the following recommendations MUST be
followed:
1. NEVER route cables so that they lie on the
floor or are subject to vehicular traffic.
2. NEVER route cables from different power
supplies along parallel paths unless they are
separated by at least 18 inches.
3. ALWAYS route cable along appropriate in-
sulators.
4. ALWAYS properly support cables at least
12 inches from metal beams. The support
should be made of a material that does not con-
duct electricity, such as most plastics. Ransburg
part number 45773-011 is one such support.
5. ALWAYS route cables from overhead, down
to the applicator(s).
Cut the high voltage cable (SSW-1064) according
to the length required and screw an EPS-4245

Sheathing is NOT a safe method of
protecting a cable from wear or traffic!

PNEUMATIC
CONNECTIONS
If required by the application, the following pneu-
matic connections can be made using 1/4" OD
tube. Reference Figure 5 and Table 3.
Pneumatic High Voltage On
Assuming AC power is on and no faults are present,
momentary activation of pressure switch PS1 will
turn high voltage on.
Pneumatic High Voltage
Off/Reset
Momentary activation of pressure switch PS2 will
turn high voltage off or reset faults. If a DC pump
is used in the application, maintained activation
of pressure switch PS2 will turn high voltage off
while maintaining voltage to the DC pump. This
is convenient for fluid flow rate checks without
high voltage.
Air Interlock
Pressure switch PS3 can be used to interlock
the high voltage with some other function using a
pneumatic signal. This interlock is most commonly
used in isolated waterborne systems where the
air signal to PS3 is lost when the safety enclosure
around the isolated fluid is opened, thereby dis-
abling high voltage.
Pneumatic High Voltage On
Output
Solenoid SOL1 turns on whenever high voltage
(CR2) is on, thereby passing air from its input to
its output. This output is most commonly used to
connect to the high voltage indicator of Ransburg
pneumatic panels to indicate when high voltage
is active.
