Important: The top connectors ar OCONUS and the bottom connectors are CONUS and output.
This unit will only output 110-132v 50/60 hz. Any attempt to use other voltages will damage equipment
and VOID the warranty.
Organization
This document is organized by situation. The potential hazards corresponding
with the situation are identified. Appropriate and inappropriate corrective
a
ctions are described.
Access to internal circuitry
UPS systems have no user servicable parts, other than those indicated as user
replacable modules. UPS systems have internal power sources and can present a
hazard to untrained service persons. Refer all servicing to trained personnel.
Smashed, pierced, or damaged enclosure
The cabinet of the UPS is damaged by dropping, piercing, crushing, etc.
Hazard #1: The UPS has an internal energy source, the battery, and represents a
potential shock or energy hazard. Action: Shut off circuit breaker feeding UPS
or detach input cord from wall receptacle. Turn off any front or rear panel main
power switches on the UPS. If the UPS has user-changable batteries, inspect for
damage and disconnect and/or remove them if undamaged. Do not ship unit without
disconnecting the battery.
Hazard #2: The UPS batteries contain liquid acid that may be released. Note: the
quantity of liquid in a UPS battery is small and is held in absorber pads, but
liquid may be squeezed out when the battery is damaged. Action: Inspect for
battery case damage or presence of liquid. Assume any liquid seen is highly
acidic. Carefully clean up using damp disposable towels, avoid contact with
skin. After removing liquid, clean affected surfaces with baking soda and water
to neutralize and remaining acidity.
UPS consumed in local fire
A fire at the UPS installation or storage site burns the UPS.
Hazard #1: Materials within the UPS are burned and the combustion products are
released. A UPS may contain many types of plastic, which will be the primary
source for combustion products. Plastic types include Polycarbonate, PVC,
Polypropylene. Printed circuit boards also contain epoxy resin. Action: assume
the combustion products of plastics are present during firefighting.
Hazard #2: The UPS continues to supply electrical power during firefighting.
Potential shock hazard for firefighters. Action: Trigger site's Emergency Power
Off switch if available. Fight fire assuming that it is a live electrical fire.
UPS emits smoke or fumes
An internal malfunction or failure causes the UPS to emit smoke or fumes.
Hazard #1: An electrical short-circuit or overload causes an internal component
to burn out. Component makes acrid smell and/or smoke. Most likely sources
include A) Epoxy from PCB or components, B) Varnish from transformers, or C) PVC
plastic from wires. Action: Unplug unit. Turn off using front or rear panel
switches. Ventilate area. If combustion is sustained, disconnect battery if
possible. Use dry chemical fire extinguishers, if necessary.
Hazard #2: An internal battery fault or battery charger failure causes the
battery to vent fumes. "Metalic" taste in the air or "rotten eggs" smell.
Possible agents released include Hydrogen Sulphide (rotten eggs smell), Hydrogen
(metalic air taste), and Oxygen. May cause eye or throat irritation, or in
severe cases, nausea. Action: Unplug unit and turn off to stop the fumes.
Evacuate area. Vent area. No medical attention required for persons exposed.
Note: absence of smell indicates release agents are gone; no further action
required.
