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.
• The unit must be grounded properly with a grounding conductor of a size equal
to or larger than that recommended by local electrical codes or the Intelligent
Fast-Charging System Ground Support Equipment (GSE) Installation Guide.
• Do not touch the uninsulated portion of the output battery connector or an
uninsulated battery terminal.
• Do not remove the cover(s). Only qualified service personnel may remove
the cover(s) on the unit. There are no user serviceable parts inside. Refer
all servicing to qualified service personnel. Opening, or attempting to install
or repair, the system by anyone other than qualified service personnel voids
the warranty.
• Disconnect the battery charger from the input power and battery connections
before servicing the unit. Lock out/tag out input power according to OSHA 29
CFR 1910.147.
• Do not use/service/repair it when it is in standing water.
• Before disconnecting the battery, stop charging by pressing the Stop button on
the front panel of all power stations. Power stations are designed to stop an
electric charge automatically, in the event of a hot disconnection, to minimize
arcing or burning of the charger connections.
• 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 cables.
• 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.
