Do not touch the battery connection terminals. Battery loop and input voltage loop is without
isolation, which may cause high voltage risk between the battery terminal and ground.
Do not connect to the equipment like hair dryer or electric heater, to ensure the safety for
UPS
1 SAFETY INSTRUCTIONS
 The power output voltage may still have 220V or 120V even not connect to the mains power.
 For the battery cable or power cord replacement, please contact our service station or
dealer to purchase, in order to avoid fire caused by inadequate capacity or heatignition.
 Do not place the battery or battery pack in the fire, which will injure due to explosion.
 Please do not open the UPS case as you will, there is risk of electric shock

2.2 Attention Items of Installation
 The UPS installation environment must be with good ventilation, away from water, flammable
gases and corrosive entities.
 Do not lie down the UPS against the wall so that front and side panel air intake hole, rear panel
air outtake hole will be unobstructed.
 The peripheral environment temperature around the UPS should be within 0 ℃~ 40 ℃.
 If dismantling the machine at low temperatures, there may be condensation droplets, users can
not install or operate it before UPS completely got dry both inside and outside, otherwise there
will be danger of electric shock.
 Place the UPS near the mains socket to cut off AC mains without any delay at any emergent
case.
ATTENTION:
 Make sure the load behind the UPS is off when users connect the load to UPS, and then turn on
the load one by one later.
 Please connect the UPS with the socket which is over-current protected. Do not connect the
UPS with the socket which rated current is less than the Maximum input current of the UPS.
 All the power socket should be configured with earthling device for safety.
 UPS could be electrified or powered no matter the input power cable is tied or not, even when
the UPS is off. The only way to cut off the output is switching off the UPS, disable the EPO and
disconnecting the mains power supply.
 For all standard type UPS, it is advised to charge the battery over 8 hours before used. Once the
AC mains power energizes the UPS, it will automatically charge the battery. Without prior
charging, UPS output remains as usual but with shorter back-up time than normal.
 When connected to motor, display equipment, laser printer etc, UPS power selection should be
based on the startup power of the load which is usually twice as rated power.
