1 ESSENTIAL INFORMATION
This UPS of PG Compact series is intended preferably to power supply circulation pumps in heating systems.
THE APPLIANCE OPERATES WITH VOLTAGE DANGEROUS TO HUMAN LIFE. PLEASE STICK TO SAFETY
INSTRUCTIONS GIVEN IN THIS GUIDE.
DO NOT DISMANTLE THE UPS COVER! THE COVER MAY BE DISMANTLED BY A QUALIFIED PERSON ONLY.
The load shall not exceed the inverter power output of 600 W.
The appliance is designed for indoor use.
It is not designed for outdoor operation, nor for operation in explosive environment.
Never charge very cold batteries (exposed to freezing temperatures).
The unit shall be placed in a suciently ventilated space. Ventilation openings shall not be covered and air
intake shall not be obstructed.
Plug the power supply cable directly to a local wall socket. Do not use any extension cables.
1.1 General Decription
When the unit is power-supplied from the grid, the electricity runs via its internal bypass directly to its
outlet socket. At the same time, the battery is being charged. In case of a power failure, the inverter turns
on and the load is fed from the integrated batteries. During charging, the temperature of the unit may rise
to circa 45 °C (normal operation state).
NOTE! MORE APPLIANCES MAY BE CONNECTED BUT ONLY WITH RESPECT TO THE POWER OUTPUT OF
THE PUMP. OF COURSE, WITH A HIGHER LOAD CONNECTED, THE BACKUP TIME GETS SHORTER.
The appliance connects to the power supply with a standard power cord with wall plug. The load is power
supplied via the 230 V socket.
WARNING! WHEN TESTING A PUMP BACKUP, NEVER UNPLUG THE PG 500 COMPACT FROM ELECTRICAL
SOCKET. DOING SO WOULD INTERRUPT THE PE LINE. DE-ENERGIZING SHALL BE DONE BY A CIRCUIT
BREAKER OR A FUSE. MAKE SURE THE PUMP IS CONNECTED IN TN-S SYSTEM, i.e. three-wire system (L,
N and PE).
When running from the battery, the LED marked“BACKUP”is lit. If the battery voltage falls to a low level, an
acoustic alarm sounds prior to disconnecting.
WARNING – Whenever handling a battery, the unit shall be turned o and disconnected from the power
supply.
Features of the UPS
Fast automatic line-to-battery switching
Built-in battery charger.
Intelligent charger control with battery overload and overcharge protection.
Protection against overload, battery overcharge and overheating.
LED indications and buzzer alarms.
The backup power supply may be disconnected from the mains only after the batteries are fully
charged. A battery can be considered fully charged when there were no power cuts for two days.
Storing a discharged battery will cause its denite destruction!

2.3 Recommended wiring
• it is recommended to use solely an installation contactor with a 230 VAC coil, 2x NO + 2x NC
• it must be ensured that the PE lead cannot be disconnected!
• unconditional separation of the circuit fed from PG 500 from the mains shall be respected

2.4 Commissioning
1. Make sure the power grid voltage corresponds to the voltage the UPS is designed for.
2. Plug the power supply cord into a wall socket. WARNING - from the moment on the batteries are being
charged.
3. Connect your pump or another load by plugging its cable into the socket of PG 500 Compact. It is
necessary to stick to a TN-S system (three-wire system, i.e. live wire is black, neutral wire is pale blue and
protective earth wire is yellow-green). 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.
4. Press ON/OFF push button to turn the UPS on. A signal will sound and all the LEDs will ash once. The
green LED will stay lit, indicating that the unit is running (standard mode, ready for backup).
5. 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 a power supply failure.
Auto test on start
After the unit is switched on, all LED indicators will blink twice. The unit is then ready for operation.
Silent mode
During battery operation, short pressing the ON/OFF button will turn on/o the buzzer alarms.
The Weak battery alarm cannot be switched o.
Auto start
If batteries went discharged and the unit switched o, it will turn on as soon as the power supply is
restored.
Overload
The unit will recognize overload and disconnect the outlet after a while in order to avoid its own
destruction.
Auto switch o
Under low battery voltage, the unit will disconnect the load and switch itself o in order to protect the
battery.
Turning o
By pressing and holding the ON/OFF button for 3 sec. the unit will be switched o.
2.5 Turning on PG Compact with no grid power
The UPS can be turned on without grid power, just from the battery.
Never disconnect 230 V power supply when the UPS is in operation, the earth protection of both PG 500
Compact and the connected load would get interrupted.
Verify that the total earth leakage current does not exceed 2.7 mA when all loads are connected (following
the EN 62040-1 standard)..
2.6 Battery replacement
The unit is equipped with two integrated 12V batteries. They shall be replaced only with batteries of the
same type. Replacement may be performed only by a qualied person. Before starting the replacement,
take o your wrist watch, rings or other metal items. Use tools with insulated handles. Do not throw the
batteries into a re, do not open/damage them. The acid inside is toxic, dangerous to skin and eyes.
Batteries shall be disposed of as dangerous waste.
