1. Introduction
Thank you for selecting this Uninterruptible Power
Supply (UPS). It provides you with a perfect protection
for connected equipment. The manual is a guide to
install and use the UPS. It includes important safety
instructions for operation and correct installation of the
UPS. If you have any problems with the UPS, please
refer to this manual before calling customer service.
2. Function overview
Guard LCD Series UPS has the following functions:
• A touch LCD panel (tapping cycles various status
display)
• Voltage stabiliser with sensitive automatic voltage
regulation (AVR)
• Frequency auto sensing
• Short-circuit, overload, surge & high/low voltage
protections
• Cold start & automatic recharge functions
• Intelligent battery management system
• Audible alarms
• Reliable protection for computers and electrical
equipment
• Monitoring software
3. Placement
• Only use in closed rooms
• Do not expose to extreme heat or humidity
•
Always take care for sufficient room around the
device for a proper ventilation
• Never connect other loads than computers or similiar
devices (except laser printers) to the UPS.
• Do not use for household appliances
About the device
4. Installation & startup
1) Inspect the UPS upon receipt. Notify the carrier and
dealer if there is damage. The package is recyclable;
save it for reuse or dispose it properly.
Caution!
Do not connect a laser printer to the UPS
output. Laser printers can draw very high surge currents
that may cause the UPS output voltage to drop and to
start an undervoltage shutdown.
2) Connect the computer (or fax machine, other equip-
ment) to the UPS and make sure that the computer is
turned off. There are also network protection sockets
on the rear, which can protect external devices, such
as network switches, from high voltages like they‘re
caused by lightning, for example.
3) Connect the UPS to the mains socket.
Attention!
Before using the UPS, charge it for at least
6 hours on a wall outlet.
4) Switch on the UPS by shortly pressing the front
switch. This has to be pushed deeply enough to rest
in the ON position, either by using the finger tip or a
small tool. The display should light up and the UPS
starts to work. In case the device is started during a
mains failure (cold start), an acoustic alarm signal is
emitted immediately.
Notices:
The batteries of the UPS are constantly charged
and supervised, as long there is mains present. The
charging time to full level may be extended by a high
load.
In backup operation (mains failure, undervoltage) the
UPS will switch itself off as soon as the batteries are
discharged down to a certain level, in order to prevent
deep discharge. The given backup time is the time the
UPS will work before it switches off. Always observe the
rated power given in the technical specifications when
connecting consumers, such as PCs. The nominal
power of the PC must not exceed the one of the UPS
or else the device might switch off because of overheat
-
ing (in normal operation) or untimely battery discharge
(backup operation). Due to apparent current and the
power factor of 0.6, the true power of, for instance, a
1000 VA model is only 600 W.
