SAFETY INFORMATION
The appliance shall be installed by a trained person. The Manual is intended for an informed person.
The contents of this Manual may change over time.
THE APPLIANCE OPERATES WITH VOLTAGE DANGEROUS TO HUMAN LIFE. PLEASE STICK
TO SAFETY INSTRUCTIONS GIVEN IN THIS GUIDE, PREVENTING THUS RISK OF ELECTRIC
SHOCK.
IMPORTANT
Wrong wiring or handling may cause damage to the appliance itself or connected devices!
Prior to beginning with installation and start of the appliance, please read the Manual carefully and
follow the instructions meticulously! These electrical appliances shall be earthed in compliance with the
valid standards. The cross-sections of the power supply cables and their current ratings shall conform
to the nominal current values on the label and to the specification of the appliance as required by a
respective rule valid for low-voltage electric appliances. Prior to installation of this electric appliance
please make sure all safety (circuit breakers and fuses) and switch-off elements are off. Batteries may
only be handled by trained, informed and experienced persons sticking to all applicable safety measures.
Before touching the battery clamps, all safety and switch-off elements at the appliance itself, batteries,
as well as safety and switch-off elements at the electric device outlet shall be switched off!
Do not put any tools, instruments or other, esp. metal items on batteries!
Do not push any objects into the appliance through the ventilation or other openings!
Use a damp cloth to clean the casing. Take care not to let moisture or water into the appliance through
the ventilation or other openings!
The appliance shall be installed in a sufficiently spacious and ventilated room enabling good access. It
shall never be exposed to weather!
Whenever handling a battery and PG 600 S, the PG 600 S shall be turned off and disconnected from
the power supply.
PG 600 S is not designed for use with an automotive battery.
The backup time depends on the power drawn by the device(s) connected to the PG 600 S. The higher
is the connected load, 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 S do not forget to switch off the PG 600 S itself
as well. Otherwise the its inverter continues to supply electricity from its battery and does not switch off
until 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 terminal of the unit’s outlet socket shall get connected to any lead of mains or any other electric
wiring. The unit is designed for a closed circuit. If the unit’s outlet got connected with the mains, there
would be a danger of destroying the connected appliances, the unit itself, and even causing harm to
health and property. The only lead that may be connected outside TN-S network is the protective
yellow-green lead.
When testing the backup function, never unplug PG 600 S from el. socket. Doing so would interrupt the
PE line. De-energizing shall be done by a circuit breaker or a fuse.
PG 600 S shall always be used with the 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 by a serviceperson at least twice a year. Cooling is
hindered by dust inside and the appliance might suffer damage from overheating.
Check annually that the battery terminals are properly tightened.

TAKING CARE OF YOUR BATTERY
The appliance is equipped with maintenance-free lead acid batteries. The following rules shall be
respected when using them:
Avoid any mechanical stress, especially by a hit.
Avoid any damage 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 batteries are to be replaced and new ones installed, their number, model, wiring manner and
capacity set by the manufacturer shall be maintained. Only an authorized serviceperson may do that.
In a room where the battery is placed the temperature shall be kept at 20 °C ± 5 °C. At temperatures
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.
After a long period of operation, the capacity of lead acid batteries decreases. This is quite normal. For
their proper operation in your system you should test their backup function at least once a year in order
to find out whether the backup period is sufficient.
Should the battery become very hot, make sounds or inflate, 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 ENSURE LONG LIFE FOR YOUR BATTERY
Never store a discharged battery. Storing a discharged battery will cause its definitive destruction.
Always charge it prior to storing and disconnect all leads from the battery 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.

2 INSTALLATION
1. Read the entire Installation and Operation Manual incl. Safety information and Taking care of your
battery.
2. Make sure the power grid voltage corresponds to the voltage PG 600 S is designed for.
3. Connect the battery using either M6 screws (for 44 and 100 Ah batteries) or M5 screws (for 18 Ah
battery). MIND THE POLARITY, + red / - blue or black. Max. torque is shown on the batteries (mostly
5-7 Nm). Fit the battery terminals with protective covers. Avoid terminal reversal!
4. Plug the power supply cord of PG 600 S into a wall socket. WARNING – PG 600 S is now switched
on and from the moment on the battery is being charged. At the same time, the internal cooling fan
also starts running.
5. Connect your pump or another load by plugging its cable into the socket of PG 600 S. It is inevitable
to stick to a TN-S wiring system.
6. Press and hold ON push button for 2 sec. to turn on PG 600 S. An audio signal will sound. The green
LED will stay lit, indicating that PG 600 S is running (standard mode, ready for backup).
7. Now you can turn on a pump or another load and test power grid operation without the inverter. The
inverter will turn on automatically at power supply failure.
2.1 RECOMMENDED WIRING
- It must be ensured that the PE lead cannot be disconnected (e.g. by pulling the coiled power supply
cable from PG 600 S)!
- Unconditional separation of the circuit fed from PG 600 S from the mains shall be respected. This
concerns not only the live but also the neutral conductors. Only the PE lead remains uninterrupted.
- In specific cases a contactor with two NO + two NC contacts configuration can be used in order to
separate the PG 600 S circuit from the mains. However it is recommended to avoid this solution.
