MAINTENANCE
>
Electrical shock hazard. ALWAYS
turn power to equipment OFF prior to
cleaning or servicing any part of the
system. Failure to do so could result in
serious injury or death.
>
Whenever removing high voltage
cable(s) from equipment, ground the plug
end of the cable(s) by contacting the plug
to electrical ground. Do not touch the
plug until it has been grounded. This will
eliminate the possibility of residual charge
causing electrical shock.
>
Whenever the high voltage cable is
removed from the LEPS5001 Power Sup-
ply, ALWAYS discharge any residual high
voltage charge from the power supply by
attaching an appropriate ground wire to
the grounded power supply container and
then inserting it down the free end of the
high voltage tube.
>
To assure continuous, efficient, trou-
ble-free operation of the LEPS5001 Pow-
er Supply and to extend its service life,
keep the exterior clean and dry. It is also
very important to keep the areas around
the high voltage cable connections clean,
to protect against static discharges.

TROUBLESHOOTING
When tracing problems, refer to the schematic
Periodically clean the unit with a clean, dry,
lint-free cloth and visually inspect for any loose
wiring connections.
Remove the high voltage cables, make sure
that they are clean and reinsert into the power
supply.
>
Apply a liberal amount of dielectric
grease (59972-00) to the high voltage ca-
ble plug before inserting back into the pow-
er supply.
>
Make sure that the high voltage cables
are fully inserted into the power supply and
that the strain relief connections are se-
cure.
NOTE
in Figure 3, illustrations in Figures 5a and 5b,
"Theory of Operation" and "Parts Identification"
sections of this manual, and the LECU5003
Control Panel service manual.
If a high voltage output problem is suspected in
the system, perform the following troubleshoot-
ing procedure:
Equipment required: Ransburg High Voltage
Test Probe and Meter (20791) AC RMS Voltme-
ter (150 volt scale or greater)
1.
With the power OFF, remove the cov-
er from the junction box that houses
>
Field repair and troubleshooting of the
LECU5003 Control Panel may require expo-
sure to potentials that can cause SERIOUS
BODILY INJURY or DEATH if proper pro-
cedures are not followed. For this reason,
troubleshooting and field repair should only
be accomplished with specific test equip-
ment by qualified electronics technicians or
authorized Ransburg representatives.
