Chapter 1 : Important Safety Warnings
Please comply with all warnings and operating instructions in this manual strictly.
Save this manual properly and read carefully the following instructions before
installing the unit. Do not operate this unit before reading through all safety
information and operating instructions carefully.
1.1 Transportation
z
z
Please transport the UPS system only in the original package to protect against
shock and impact.
1.2 Preparation
z
z
Condensation may occur if the UPS system is moved directly from cold to warm
environment. The UPS system must be absolutely dry before being installed.
Please allow at least two hours for the UPS system to acclimate the environment.
z
z
Do not install the UPS system near water or in moist environments.
z
z
Do not install the UPS system where it would be exposed to direct sunlight or
near heater.
z
z
Do not block ventilation holes in the UPS housing.
1.3 Installation
z
z
Do not connect appliances or devices which would overload the UPS system (e.g.
laser printers) to the UPS output sockets.
z
z
Please do not attached half-sinewave load or motor load to the UPS.
z
z
Place cables in such a way that no one can step on or trip over them.
z
z
Do not connect domestic appliances such as hair dryers to the UPS output sockets.
z
z
The UPS can be operated by any individuals with no previous experience.
z
z
Connect the UPS system only to an earthed shockproof outlet which must be
easily accessible and close to the UPS system.
z
z
Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of
your computer) to connect the UPS system to the building wiring outlet (shock-
Amplon INX Series
1
Chapter 1 Important Safety Warnings
proof outlet).
z
z
Please use only VDE-tested, CE-marked power cables to connect the loads to
the UPS system.
z
z
When installing the equipment, it should ensure that the sum of the leakage current of the UPS and the connected devices does not exceed 3.5mA.
1.4 Operation
z
z
Do not disconnect the mains cable on the UPS system or the building wiring
outlet (shockproof socket outlet) during operations since this would cancel the
protective earthing of the UPS system and of all connected loads.
z
z
The UPS system features its own, internal current source (batteries). The UPS
output sockets or output terminals block may be electrically live even if the UPS
system is not connected to the building wiring outlet.
z
z
In order to fully disconnect the UPS system, rst press the OFF/ ENTER button
to disconnect the mains.
z
z
Prevent no uids or other foreign objects from inside of the UPS system.
1.5 Maintenance, Service and Faults
z
z
The UPS system operates with hazardous voltages. Repairs may be carried out
only by qualied maintenance personnel.
WARNING:
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.
z
z
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.
z
z
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 batteries.
WARNING:
Risk of electric shock. The battery circuit is not isolated from the input
voltage. Hazardous voltages may occur between the battery terminals and
the ground. Before touching, please verify that no voltage is present!
2
z
z
Batteries may cause electric shock and have a high short-circuit current. Please
take the precautionary measures specied 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.
z
z
When changing batteries, install the same number and same type of batteries.
z
z
Do not attempt to dispose of batteries by burning them. This could cause battery
explosion.
z
z
Do not open or destroy batteries. Escaping electrolyte can cause injury to the
skin and eyes. It may be toxic.
z
z
Please replace the fuse only with the same type and amperage in order to avoid
re hazards.
z
z
Do not dismantle the UPS system.
