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 sufficiently ventilated space. Ventilation openings shall not be covered and air

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 off and disconnected from the power
supply.
