Safety Warnings and EMC Instructions
This manual contains important instructions that you should follow during installation and maintenance of the
UPS and batteries. Please read all instructions before operating the equipment and save this manual for future
reference.
UPS Warnings
• Install your UPS indoors, away from excess moisture or heat, direct sunlight, dust and conductive contami
-
nants.
• Install your UPS in a structurally sound area. Your UPS is extremely heavy; take care when moving and lift
-
ing the unit.
• Only operate your UPS at indoor temperatures between 32°F and 104°F (between 0°C and 40°C).
• Leave adequate space around all sides of the UPS for proper ventilation.
• Do not install the UPS near magnetic storage media, as this may result in data corruption.
• Do not mount unit with its front or rear panel facing down (at any angle). Mounting in this manner will se
-
riously inhibit the unit’s internal cooling, eventually causing product damage not covered under warranty.
• This UPS should be connected with a grounded system. NEC and local electrical codes apply.
• The power supply for this unit must be single-phase rated in accordance with the equipment nameplate.
It also must be suitably grounded
• Use of this equipment in life support applications where failure of this equipment can reasonably be ex
-
pected to cause the failure of the life support equipment or to significantly affect its safety or effectiveness
is not recommended. Do not use this equipment in the presence of a flammable anesthetic mixture with
air, oxygen or nitrous oxide.
• Connect your UPS power module’s grounding terminal to a grounding electrode conductor.
• The UPS is connected to a DC energy source (battery). The output terminals may be live when the UPS is
not connected to an AC supply.
Maintenance Warnings
• Service and repair should be done only by trained personnel. During any service work to the UPS, it should
be turned off or manually bypassed. Note that potentially lethal voltages exist within this unit as long as
the battery supply is connected.
• Your UPS power module and battery module(s) do not require routine maintenance. Do not open them for
any reason. There are no user-serviceable parts inside.
• Even after the unit is disconnected from the mains, components inside the UPS system are still connected
to the battery packs which are potentially dangerous.
• Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no
current is present and no hazardous voltage exists on PCB components
• Fuses should be replaced only by factory authorized personnel. Blown fuses should be replaced only with
fuses of the same rating and type.
• Verify that no voltage between the battery terminals and the ground is present before maintenance or
repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may
occur between the battery terminals and the ground.
Battery Warnings
• Do not operate your UPS without connecting it to an external battery module.
• Batteries can present a risk of electrical shock and burn from high short-circuit current. Observe proper
