Uninterrupble 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 insulaon.
Maintenance, Service, and Faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualied mainte-
nance personnel.
• Cauon - risk of electric shock. Even aer the unit is disconnected from the mains (building wiring outlet),
components inside the UPS system are sll connected to the baery and electrically live and dangerous.
• Before carrying out any kind of service and/or maintenance, disconnect the baeries 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 o the unit and unplug it form the AC power source before servicing the
baery.
• Only persons are adequately familiar with baeries and with the required precauonary measures may
replace baeries and supervise operaons. Unauthorized persons must be kept well away from the bat-
teries.
• Cauon - risk of electric shock. The baery circuit is not isolated from the input voltage. Hazardous volt-
ages may occur between the baery terminals and the ground. Before touching, please verify that no
voltage is present!
• Baeries may cause electric shock and have a high short-circuit current. Please take the precauonary
measures specied below and any other measures necessary when working with baeries:
» Remove wristwatches, rings and other metal objects
» Use only tools with insulated grips and handles.
• When changing baeries, install the same number and same type of baeries.
• Do not aempt to dispose of baeries by burning them. This could cause baery explosion.
• Do not open or destroy baeries. Escaping electrolyte can cause injury to the skin and eyes. It may be
toxic.
• When replacing baeries, replace with the same type and number of baeries or baery packs.
• Do not dismantle the UPS system.
• A baery can present a risk of electrical shock and high short-circuit current. The following precauons
should be observed when working on baeries:
» 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 baeries.
» Disconnect charging source prior to connecng or disconnecng baery terminals.
» Determine if baery is inadvertently grounded. If inadvertently grounded, remove source from
ground. Contact with any part of a grounded baery can result in electrical shock. The likelihood
of such shock can be reduced if such grounds are removed during installaon and maintenance.
Installaon and Setup
NOTE: Before installaon, 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.
