DVS Fast Charging System
ELECTRIC SHOCK CAN KILL: Touching live electrical parts can cause
fatal shocks or severe burns. The battery terminals are always
electrically live, and the output circuit is live whenever the battery is
connected or being charged. The input power circuitry and internal
DANGER
circuits are live whenever input power is on. An incorrectly installed or
improperly grounded charger is a hazard.
 The unit must be grounded properly with a grounding conductor of size equal to or larger
than that recommended by local electrical codes or the installation section of this manual.
 Do not touch the uninsulated portion of the output battery connector or an uninsulated
battery terminal.
 Do not remove the cover. There are no user serviceable parts inside. Refer all servicing to
qualified service personnel. Opening the system or attempted repair by other than qualified
service personnel, voids the warranty.
 Disconnect battery charger from input power and battery connections before installing or
servicing. Lockout/Tagout input power according to OSHA 29 CFR 1910.147.
 Do not use when in standing water.
 Before disconnecting the battery, turn off the charger by pressing the stop button on the
front panel. The DVS is designed to automatically stop a charge event to minimize arcing
or burning of the charger connections in the event of a hot disconnect.
 The charging leads must be capable of the full rated current of the DVS, and inspected
frequently for wear, cuts and abrasion. Do not use worn, damaged, undersized, or poorly
spliced cable.
 The DVS power connector may be damaged by misuse or abuse. Frequently inspect the
connector for cracking, pitting of contacts, fraying of wires or signs of connector fatigue.
Should any indication be present, immediate replacement of the connector will be
necessary.
 Do not wear rings, watches, necklaces, tie clips, or conductive jewelry when working with
batteries, as a short circuit through conductive jewelry may cause severe burns.
BATTERY GASES AND ELECTROLYTE CAN BE HAZARDOUS:
DANGER
Charging batteries produces fumes and gases that may be
hazardous.
 Charging batteries may leak corrosive electrolyte that can cause skin and eye irritation and
damage equipment and clothing. Avoid contact and follow battery manufacturer's
recommended practices for cleaning the battery pack.
 Thoroughly wash all items brought into contact with battery electrolyte with a solution of
baking soda and water.
 Batteries produce explosive gases. Do not smoke, perform operations that cause sparking,
or have an ignition source near batteries.
 Ventilate the area to prevent the buildup of fumes and gases.
WARNING
IMPROPER INSTALLATION CAN CAUSE FIRE
 Do not install or place unit on, over or near combustible surfaces.
