Ransburg HV Junctin Tank LEPS5000 - Manual (Page 12)

>
This manual MUST be read and thor-
oughly understood by ALL personnel who
operate, clean and maintain this equipment.
Special care should be taken to ensure
that the WARNINGS and requirements for
operating and servicing safely, are followed.
W A R N I N G
!
The LEPS5000 must be installed outside of
the hazardous area of the spray booth (refer to
NFPA 70, Article 516 or NFPA 33).
GROUND CABLE
Important: Make sure that the ground wire as-
sembly supplied with the power supply (Rans-
burg part number 70539) is connected from the
grounding lug, located on the top of the junction
tank, to a true earth ground. (See Figure 3.)
HIGH VOLTAGE CABLE
(Routing & General Guidelines)
SSW-1064
Unshielded High Voltage Cable
According to OSHA standard 1910.107, (h)(5),
high voltage cable “...shall be properly insu-
lated and protected from mechanical injury or
exposure to destructive chemicals.” To facilitate
compliance with this code, the following recom-
mendations 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.
>
Sheathing is NOT a safe method of
protecting a cable from wear or traffic.

>
Do NOT make the approach to the ap-
plicator at or below floor level. Route high
voltage cables from overhead down to the
applicator. Routing the cables up and out
of the way will result in less exposure to
dirt and traffic.

3. ALWAYS route cable along appropriate
stand-off insulators.
4. ALWAYS properly support cables at least 12
inches from metal beams. The support should
be made of material that does not conduct
electricity, such as most plastics. Ransburg
part number 45773-011, stand-off insulator, is
one such support.
5. ALWAYS route cables from overhead, down
to the applicator.
6. If an insulating sheathing is to be used
around the cable, it MUST be of a non-ab-
sorbent material, such as polyethylene, and
should be routed to prevent contact with or
entrapment of solvents or cleaning solutions.
The cable should NOT be sheathed from its
last point of physical support after it enters
the spray area, to the applicator! Insulating
sheathing is available from Ransburg as part
number 9704-13.
7. If a cable must be routed through a metal
(or conductive) surface, cut an opening with
a minimum radius of five inches and mount a
non-conductive bulkhead therein. Route the
cable through the center of the bulkhead and
secure it with a suitable, non-conductive strain
relief. (The non-conductive bulkhead may be
any shape as long as there is at least five
inches (18 inches preferred) from the nearest
conductor.)
8. Make cable runs as short as possible by
mounting the power supply and junction tank
as close to the spray device as codes and the
physical environment allow.
