BEFORE YOU

400 Assembly.
• Make sure you also read the IMPORTANT SAFETY INSTRUCTIONS below.
• Be sure to leave these instructions in a safe and easily accessible location for
future reference.
• Only qualified personnel, familiar with the local code, should install and service this
charger.
• Read and understand the manufacturer’s instructions and your employer’s safety
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 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
400 is designed to automatically stop a charge event to minimize arcing or burning of the charger connections in
the event of a hot disconnect.
