1. Safety Instructions
1.1 Installation
Condensation may occur if the UPS system is moved directly from a cold to
a warm environment. The UPS system must be absolutely dry before being
installed. Please allow an acclimatization time of at least two hours.
Do not install the UPS system near water or in damp environments.
Do not install the UPS system where it would be exposed to direct sunlight
or near heat.
Do not connect appliances or items of equipment which would overload the
UPS system (e.g. laser printers) to the UPS output terminals or sockets.
Place cables in such a way that no one can step on or trip over them.
Assure to connect with the earth reliably.
Connect the UPS only to a socket outlet which is earthed shockproof type.
The building wiring socket outlet (shockproof socket outlet) must be easily
accessible to close to the UPS.
With the installation of the equipment, the sum of the leakage current of the
UPS and the connected load does not exceed 3.5mA.
Do not block ventilation openings on the UPS’s housing. Ensure the air
vents on the front, side and rear of the UPS are not blocked. Recommended at
least 25cm of space on each side.
This UPS receives power from more than one source-disconnection of AC
source and the DC source is required to de-energize this unit before servicing.
An additional circuit breaker or fuse with rating 15A and breaking capacity
3kA shall be used between power source and input when installation this unit.
1.2 Operation
For safety consideration, do not disconnect the mains cable on the UPS or
the building wiring socket (grounded shockproof socket) during operation the
grounding for the UPS and all loads connected will be disconnected.
The UPS features its own, internal current source (batteries). You may be
electric shocked when you touch the UPS output sockets or output terminal
block even if the UPS is not connected to the building wiring socket.
In order to fully disconnect the UPS, first press the OFF button to turn off
the UPS, and then disconnect the mains lead.
Ensure that no liquid or other external objects can enter the UPS.
Do not remove the enclosure. This system is to be serviced by qualified
service person only. There are NO USER SERVICEABLE PARTS inside the
UPS.
Remove the protective panel only after disconnecting the terminal
connections.
1.3 Maintenance, Servicing and Fault
The UPS operates with hazardous voltages. Repairs may be carried out
only by qualified maintenance/service person.
Caution - risk of electric shock. Even after the unit is disconnected from the
mains power supply (building wiring socket), components inside the UPS are still
connected to the battery which are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the
batteries. Verify that no current is present and no hazardous voltage exists in the
capacitor or BUS capacitor terminals.
Batteries must be replaced only by qualified person.
Caution - risk of electric shock. The battery circuit is not isolated from the
