4. Do not install the equipment near any sources of heat, such as heating devices
like electric heaters or furnaces.
5. Please make sure there is adequate space for ventilation or maintenance around
the equipment. Please follow the instructions in the manual for installation.
6. For the purpose of cleaning, please use dry and non-conductive tools to wipe
down the equipment.
7. In case of a fire, please use dry powder extinguishers. Liquid fire extinguishers are
not allowed.
8. Please make sure the floor on which the equipment is installed is strong enough to
support the weight of the equipment with battery.
9. Please make sure the total wattage requirements of the loads do not exceed the
power rating of your UPS or the capacity of the battery.
Prohibited Activities
1. Having service personnel without authorization from SANTAK to open the UPS
cabinet, which contains lethal voltages is not allowed. Unauthorized opening may
cause an unsafe condition, and will void the warranty.
2. Applying the following types of loads , the application, configuration, management
and maintenance of which may be subject to special requirements, please inquire
from dealers or SANTAK in advance:
A. High-precision industrial, scientific-research or medical instruments;
B. Facilities of which malfunctions may lead to life-threatening situations, such as
elevator;
C. Loads with large inrush current and negative power consumption;
3. Exposing batteries to fire, which may cause explosions.

Electrical Safety
1. Please make sure that the grounding is firmly connected and the wiring and
battery polarity are correctly connected.
2. Battery protection devices must be configured with a suitable over-current circuit
breaker.
3. Before you remove your UPS or reconnect the wiring, please shut down your UPS
and disconnect the air circuit breaker and the battery to ensure that the output
terminals do not carry live voltage which may cause an electric shock.
4. To ensure safety and the best performance of your UPS, please choose from
accessories recommended by SANTAK.
5. A proper four-pole over-current circuit breaker shall be installed before connecting
clients to your UPS to prevent electric shock by disconnecting all the input wiring.
Battery Safety
1. The service life of a battery is shortened as the ambient temperature rises.
Regular battery replacement ensures that your UPS work well and provides sufficient
back-up time.
2. Battery replacement and maintenance must be performed by authorized
personnel with professional knowledge in battery. Please replace an equivalent
number of batteries of the same type and model.
3. There are risks of electric shock and short circuit with the battery. Please observe
the following rules while replacing the battery to reduce the risks of electric shock:
A. Do not wear watches, rings or any other metallic objects;
B. Use insulated tools;
C. Wear rubber shoes and gloves;
D. Do not place metal tools or any other metallic accessories on the battery;
E. Disconnect the loads connected to the battery before removing terminals from the
battery.
4. Do not expose the battery to fire to avoid the risks of explosion that may result in
personal injury.
5. Non- professionals shall not open or disassemble the battery as electrolytes in the
battery contain strong acid and other dangerous substances which may cause
damage to skin and eyes. Please clean with water immediately and seek medical
assistance if the electrolytes come in contact with human skin.
6. Do not connect the battery positive and negative poles as it may cause short circuit.
Over current protection device is needed to avoid risks of burns or electric shock.

Maintenance
1. The working environment and storage method of UPS can affect its service life
and reliability. Do not use your UPS in any of the following environments where:
A. the temperature and humidity are outside the required ranges, i.e.0-40°C and 0-95%
humidity; or
B. your UPS is at high risks of vibration and collision;
C. there are metal shavings, corrosive materials, salt and flammable gases.
2. If you plan to leave your UPS idle for a long time, please store it in dry conditions
with an ambient temperature ranging between -25-55°C. Before you start up your
UPS, please keep it in an environment where the ambient temperature is at or above
0°C for 2 hours or longer.
3. Keep the air inlets and outlets clear for proper ventilation. Poor ventilation will
cause the temperature inside your UPS to rise, shortening the service life of the
components and that of your UPS.
4. The battery should be charged at least once every three months if it is left idle and
stored in an environment with a room temperature, or at least once every two months
if left idle in a high temperature environment; each charge should take more than10
hours; do not discharge with no loads connected or discharge for more than 14 hours
continuously.
