MAINTENANCE
WARNING: ELECTRICAL SHOCK
HAZARD — Before inspecting or
cleaning inside cabinet, turn OFF
and remove fuses of disconnect
switch (supplying AC power to
charger) and disconnect battery.
Inspection And Cleaning
For uninterrupted, satisfactory service from this
charger, it's necessary to keep unit clean, dry, and
well ventilated. At least every three months, or
more often as necessary, wipe and blow out all
dirt from unit's interior components, with clean,
dry air of not over 25 psi (172 kPa) pressure. Use
a hand bellows if compressed air isn't available.
A certified technician can remove modules and
clean the heat sink with compressed air or a wire
brush, if necessary.
Check and tighten all electrical connections as
necessary to eliminate unnecessary losses and to
avoid subsequent trouble from overheating or open
circuits. Check for broken wiring or damaged
Insulation on wiring.
WARNING: ELECTRICAL SHOCK
HAZARD — Failure to keep internal
parts clean and dry may allow
transformer (s) to short out,
causing secondary circuits to
carry dangerously high voltage.
Be sure to close all charger cabinet panels after
any servicing, to assure proper flow of cooling air
through unit and to protect internal components.
WARNING: ELECTRICAL SHOCK
HAZARD — All cabinet panels must
be closed to protect personnel from
contact with hazardous voltages.

Fuse Replacement
The input and output of the Evolution modules are
protected by 'fast clearing' fuses. Three AC fuses on
the input and a DC fuse on the output.
CAUTION: The use of any other type
fuse besides the "fast-clearing" type
may cause damage to silicon diodes.
