Read the following precautions before you install the UPS.
•
This UPS contains its own energy source (batteries).
•
The DC mains power must be turned off before connecting or disconnecting wires to the terminals.
•
Use RED wire for (+) positive and BLACK for (-) negative wire connections.
•
Make sure the wires do not touch to chassis during their connection.
•
Always connect the DC mains input and load output wires first, then the UPS battery terminals labeled
(BAT +/-), and finally to the EBM.
•
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled, indoor
environment, free of conductive contaminants. Ambient temperature must not exceed 50°C (122°F). Do
not operate near water or excessive humidity (95% max).
•
To comply with international standards and wiring regulations, the total equipment connected to the
output of this UPS must not have an earth leakage current greater than 1.5 milliamperes.
•
To guarantee sufficient convection cooling, please keep a clearance of 50mm above, 180mm below, and
10mm lateral distance of between devices.
•
Note that the enclosure of the device can become very hot depending on the ambient temperature and
load of the power supply. Risk of burns!
•
Do not introduce any objects into the unit.
•
The UPS and EBM unit should be installed in minimum IP54 rated enclosure.
•
The units must be installed in a cabinet or room (condensation free environment and indoor location) that is
relatively free of conductive contaminants.
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED
SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the UPS.
•
For use in a controlled environment.
•
Batteries can present a risk of electrical shock or burn from high short-circuit current. Observe proper
precautions. Servicing should be performed by qualified service personnel knowledgeable of batteries and
required precautions. Keep unauthorized personnel away from batteries.
•
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
•
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
