QUANTUM CHARGER PREVENTIVE MAINTENANCE
The Quantum charger streamlined design emphasizes ease of maintenance. Preventive Maintenance is
mandatory annually to maintain warranty – twice a year is recommended.
Below is the list of the maintenance procedures:
1)Air Filter
Regularly inspect air filter and clean or replace as necessary. Location and environmental conditions
must be taken into account when determining the frequency that the filter is cleaned or replaced. The
air filter can be blown out or washed in warm soapy water (the filter must be completely dried prior to
reinstall).
The following are general guidelines in regard to cleaning or replacing the air filter:
Environmental
Condition
Application Example

Replacement Cycle
Normal
A normal daily operation Conventional Charging
basic material handling of clean product in dry
environments.
Annually
Severe
Extended operating hours or constant use when
Fast or Opportunity charging in dusty, hot but dry
environments.
Bi-Annually
Extreme
All dusty or sandy conditions such as in cement
plants, lumber or flour mills, coal dust or stone-
crushing areas.
Corrosive atmosphere such as in chlorine or salt-
sea air environments.
Quarterly
2)Power modules Inspection
Pull out the power module and Inspect DC connector for any discoloration or deformation. Reinstall
the PMs and ensure that the PMs are fully seated, and the tabs are flushed. Tighten the bolts all
the way by hand and make sure they are secured.

4)Battery Cables Inspection
Regularly inspect the DC cables for wear. If the DC cables or connectors become worn or damaged, they
should be immediately replaced with a cable of the same rating by qualified personnel. Inspect the
connector housing and make sure there is no damage. Inspect the tips of the battery connector for signs of
pitting due to arcing. Replace the tips as needed.
Inspect the DC fuse and battery cables, make sure the torque lines are straight. If a torque line is not
straight, set torque on the DC connection.
Torque nuts on external threaded Power Elements on DC Backplanes to a maximum of 79 lbf*inch +0/-
10% (6.6 lbf*ft) (9.0N*m). See next image for an example of an external threaded Power Element.
CAUTION, DO NOT OVERTIGHTEN AS THIS MAY DAMAGE THE PCB.
Torque all other fasteners for DC main fuses or DC output cables to 120 lbf*inch +0/-10% (10 lbf*ft)
(13.5N*m).
