exposed to weather!
For anyhandling the battery and PG 600 SX, the backup power supply shall be turned off and disconnected from the
mains.
The appliance is not designed to be operated with an automotive starter battery.
The backup time depends on the power drawn by the devices connected to PG 600 SX. The higher isthe power
consumption, the shorter is the backup time.
PLEASE RESPECT THE FOLLOWING INSTRUCTIONS
The appliance may be installed by authorized staff only!
When switching off the electric appliance fed by PG 600 SX do not forget toswitch offthe PG 600 SX itself as well.
Otherwise the PG 600 SX’s inverter continues to supply electricity from its batteries and does not switch offuntil the
battery voltage drops below the set min. value.
Even if the appliance is turned off, the battery voltage is still present at the clamps.
No contact of the UPS outlet socket shall get connected to anylead of mains or anyother electric wiring. The UPS is
designed for a closed circuit. Ifthe UPS outlet got connected with the mains, there would be a danger of destroying the
connected appliances, the UPS itself, and even causing harm to health and property. The only lead that may be
connected outside the TN-S network isthe protective yellow-green lead.
When testing a pump backup, never unplug the PG 600 SX from el.socket. Doing so would interrupt the PE line. De-
energizing shall be done by a circuit breaker or fuse.
PG 600 shall be always used with a battery connected.
Do not leave the appliance turned off for more than 6 months unless its batteries had been fully charged.
The appliance should be completely cleaned bya serviceperson at least twice a year. Cooling and heat exchange are
hindered byexcess dustinside and the appliance might getoverheated.
Check annually that the battery terminals are properly tightened.
TAKING CARE OFYOUR BATTERIES
The appliance is equipped with maintenance-free lead acid batteries. The following rules shall be respected when using
them:
Avoid anymechanical stress, especially bya hit.
Avoid anydamage to the battery casing and do not attempt to open it. The acid inside is toxic, dangerous to skin and
eyes! In no case shall the battery be exposed to high temperatures or flames. There is a risk of explosion!
When the battery isto be replaced and a new one installed, its number, model, wiring manner and capacity set bythe
manufacturer shall be maintained. Only an authorized serviceperson may do that.
In a room where the battery isplaced the temperature shall be kept at20 °C ± 5 °C. Attemperatures above 20 °C the
battery lifetime deteriorates, at temperatures below 20 °C the battery capacity deteriorates.

SAFETY INSTRUCTIONS REGARDING THE BATTERY
Never wire and charge very cold batteries (exposed to freezing temperatures).
A battery represents a serious threat to human health and the environment. It shall be disposed of in compliance with a
valid legislation.
Be extremely careful when using metal items and tools near the battery.
When working with the appliance, refrain from smoking and using open flame! Do not use water to extinguish eventual
fire, danger of explosion!
Gases develop in all lead acid batteries during charging. In traditional unsealed batteries these gases escape into the
air. In batteries with pressure valves most of these gases recombine inside the battery and just a very small portion
escapes into the air.
Always ensure good ventilation for battery cabinets or rooms (at least 1 l of air per hour). Hydrogen gas may explode
and cause serious injuries and fire.
Acid lead batteries suffer from reduced capacity when used for a long time. This is quite normal. In order to be sure
about its proper working, test its backup function at least once a year and verify if its backup time is sufficient.
Should the battery get very hot, start making sounds or inflating, leave the room immediately!
ACID BURN INJURY Should the acid get in contact with skin, take off immediately all
contaminated clothing, and wash immediately with plenty of
water, use sterile gauze bandage and special medical aids.
In case of contact of acid with eyes, rinse immediately with
plenty of water and call emergency and ambulance. In all
emergency, life-threatening situations contact a doctor asap.
.
.
HOW TO EXTEND THE SERVICE LIFE OF YOUR BATTERY:
Never store a discharged battery. Storing a discharged battery will cause its definite destruction!
Always charge a battery prior to storing and disconnect all leads from its poles. The battery may be stored for a longer
time in this manner only. At the same time, it is recommended to charge it every 3 months. Older batteries shall be
checked more frequently.
Should the UPS be disconnected from the mains for a longer time, it is unconditionally necessary to disconnect also the
battery from the UPS.
