DVS Fast Charging System
DANGER
 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 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.
 Using the OFF and/or Emergency Power OFF (EPO) button does NOT remove the input
power completely from the system. 120VAC still exists at R1 on the Door Assembly, on
TB2 on the left interior wall, and on TB1 on the interior top wall of the PowerStation even
after the OFF and/or EPO button has been pressed.
 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.
 The charging leads must be capable of the full rated current of the DVS/MVS 330 system,
and inspected frequently for wear, cuts and abrasion. Do not use worn, damaged,
undersized, or poorly spliced cable.
 The DVS/MVS 330 power connectors 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.
DANGER
 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.

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 circuits are live
whenever input power is on. An incorrectly installed or improperly
grounded charger is a hazard.
BATTERY GASES AND ELECTROLYTE CAN BE
HAZARDOUS:
Charging batteries produces fumes and gases that may be hazardous.
