1. INTRODUCTION & SAFETY RULES
1.1 INTRODUCTION
More than ever before, today's advanced electronic equipment, with complex integrated
circuits and other sensitive electronics, needs a stable and continuous AC power supply to
operate correctly.
While the power coming from the wall socket outlet is often unreliable, a
LP 31
UPS provides
the security of completely uninterrupted power.
A compact, truly on-line system, the
LP 31
UPS protects your equipment from all forms of
power interference, including complete power failure.
A simple and elegant circuit design, together with extensive protection against abnormal
operating conditions (e.g. overload, short circuit, overheating), makes the
LP 31
exceptionally reliable.
1.2 SAFETY
RULES
1.2.1 General
This equipment can be operated by anyone, without any special training.
WARNING: RISK OF ELECTRICAL SHOCK
The UPS contains its own energy source: batteries.
The output terminals may be electrically live, even when the UPS is disconnected from the
mains. Dangerous voltages may be present during battery operation.
The batteries must be disconnected during maintenance or service work.
The UPS contains potentially hazardous voltages.
Do not open the UPS, there are no user serviceable parts inside.
All maintenance and service work should be performed by qualified service personnel.
1.2.2 Installation
The UPS is intended to be used in normal domestic and office situations.
The UPS may only be installed by trained personnel.
The UPS should only be powered from a three-phase, four-wire AC source equipped with a
protective earth connection.
Do not install the UPS in an excessively humid environment or near water.
Avoid liquids or any foreign object to get into the UPS.
The unit must be placed in a sufficiently ventilated area; the ambient temperature should not
exceed 40°C.
Optimal battery lifetime is obtained if the ambient temperature does not exceed 30°C.
It is important that ventilation air can move freely around and through the unit.
Do not block the air vents.
Avoid locations in direct sunlight or near heat sources.
Do not connect household appliances such as electric heaters, toasters or vacuum cleaners
to the UPS.
