Uninterruptible Power Supply
• The EPO, RS-232 and USB circuits are an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must
be separated from any hazardous voltage circuits by reinforced insulation.
Maintenance, Service, and Faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified mainte-
nance personnel.
• Caution
- risk of electric shock. Even after the unit is disconnected from the mains (building wiring outlet),
components inside the UPS system are still connected to the battery and electrically live and 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 in the terminals of high capability capacitor such as
BUS-capacitors.
• To avoid electrical shock, turn off the unit and unplug it form the AC power source before servicing the
battery.
• Only persons are adequately familiar with batteries and with the required precautionary measures may
replace batteries and supervise operations. Unauthorized persons must be kept well away from the bat-
teries.
• Caution
- risk of electric shock. The battery circuit is not isolated from the input voltage. Hazardous volt-
ages may occur between the battery terminals and the ground. Before touching, please verify that no
voltage is present!
• Batteries may cause electric shock and have a high short-circuit current. Please take the precautionary
measures specified below and any other measures necessary when working with batteries:
»
Remove wristwatches, rings and other metal objects
»
Use only tools with insulated grips and handles.
• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose of batteries by burning them. This could cause battery explosion.
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be
toxic.
• When replacing batteries, replace with the same type and number of batteries or battery packs.
• Do not dismantle the UPS system.
• A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
»
Remove watches, rings, or other metal objects.
»
Use tools with insulated handles.
»
Wear rubber gloves and boots.
»
Do not lay tools or metal parts on top of batteries.
»
Disconnect charging source prior to connecting or disconnecting battery terminals.
»
Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from
ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood
of such shock can be reduced if such grounds are removed during installation and maintenance.
Installation and Setup
NOTE:
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. Please keep
the original package in a safe place for future use.
