supply cables and their current ratings shall conform to the nominal values on the label and to the specication 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 circuit breakers and fuses are o󰀨.
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-o󰀨 elements at the appliance itself, batteries and their outlets
shall be switched o󰀨!
Do not put any tools, instruments or other, esp. metal items on batteries!
Avoid touching the terminal block or battery clamps with bare hands or conductive items held in hands!
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 su󰀩ciently spacious and ventilated room enabling good access. It shall never be
exposed to weather!
PLEASE RESPECT THE FOLLOWING INSTRUCTIONS
The appliance may be installed by authorized sta󰀨 only!
When switching o󰀨 the electric appliance fed by PG 1000 do not forget to switch o󰀨 the PG 1000 itself as well. Otherwise
the PG 1000’s inverter continues to supply electricity from its battery and does not switch o󰀨 until the battery voltage
drops below the set min. value.
Do not leave the appliance turned o󰀨 for more than 6 months unless its batteries had been fully charged (charging
shall continue for at least 2 hours after the oating voltage had been reached).
The appliance should be completely cleaned by a serviceperson at least twice a year. Cooling is hindered by dust
inside and the appliance might su󰀨er damage from overheating.
TAKING CARE OF YOUR BATTERY
The appliance is equipped with maintenance-free lead acid battery. The following rules shall be respected when using it:
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!
Do not short-circuit the battery cables, it is highly risky, causing damage to the battery!
In no case shall the battery be exposed to high temperatures or ames. There is a risk of explosion!
When the battery is to be replaced and a new one installed, its 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
A battery represents a serious threat to human health and the environment. It shall be disposed of in compliance
with a valid legislation. The appliance shall be stored in a dry, ventilated room, protected from moisture and e󰀨ects of
chemicals.
When working with the appliance, refrain from smoking and using open ame!
Do not use water to extinguish eventual re, 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.
Hydrogen gas may explode and cause serious injuries and re.
Always ensure good ventilation for battery cabinets or rooms (at least 1 l of air per hour).

ACID BURN INJURY
CALL A DOCTOR OR AMBULANCE IMMEDIATELY
This battery is sealed, valve-controlled, with acid in a gel
form or soaked in microscopic-porous vitreous substance in a
sealed case.
If a battery case su󰀨ers damage, the acid may leak out. In such
a case internal short circuit may occur or a person may get
splashed with sulphur acid!
Should the acid get in contact with skin, take o󰀨 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.
KEEP IN MIND THAT EVEN IF THE APPLIANCE IS TURNED OFF, THE BATTERY VOLTAGE IS STILL PRESENT IN
THE WIRING AND AT THE CLAMPS.
HOW TO ENSURE LONG LIFE FOR YOUR BATTERY:
Always store the battery fully charged. When it is not connected to an operational charger, always disconnect also the
battery poles. Even a small discharge current for a longer time will cause irreversible damage to the battery.
Never store a discharged battery. 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
recommended 3 months. Older batteries shall be checked more frequently.
Battery poles shall never get connected to each other. That means a short circuit that can cause a
battery explosion with subsequent re.

REGULUS - Zdroj PG 1000 - www.regulus.cz
1.1 GENERAL DESCRIPTION
When PG 1000 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 battery.
A battery connects to PG 1000 using cables tted with cable lugs.
Max. battery capacity for UPS PG 1000 is 100 Ah.
During charging, the temperature of PG 1000 may rise to circa 45 °C (normal operation state).
WARNING! The battery shall be connected for standard operation, otherwise the appliance cannot be turned on.
WARNING! The battery shall be connected to the terminals marked with the same polarity (+ red / - blue or black). The
poles between a battery and PG 1000 must not get swapped, there is a risk of damage to PG 1000.
NOTE! MORE APPLIANCES MAY BE CONNECTED BUT ONLY WITH RESPECT TO THE POWER OUTPUT OF
THE PUMP AND PG 1000.
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 1000 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, BACKUP MODE is shown on the display. If the battery voltage falls to a low level, an
acoustic alarm sounds prior to disconnecting PG 1000, and a low battery symbol appears.
WARNING – Whenever handling a battery and PG 1000, the PG 1000 shall be turned o󰀨 and disconnected from the
power supply.

BATTERY CONNECTION
The battery terminal on PG 1000 is tted with M6 sized PLUS and MINUS contacts. A battery is to be wired using a pair
of cables with lugs at the PG 1000 end, and cable lugs or other terminals at the battery end (depends on the battery
model).
Since a battery features extra low tension (12 V), it is important that its connection to the PG 1000 is as good as possible.
This way contact resistance will be avoided that would compromise both the backup and battery charge time. For longer
leads, a larger cross section shall be selected for the cables in order to prevent higher voltage drops.
Important:
Check annually that the battery terminals are properly tightened.
COMMENTS ON UPS PG 1000 OPERATION
As new batteries are not cheap, e󰀨orts may emerge to save money by using old automotive batteries. However, these
batteries are worn o󰀨 internally and won’t charge to their full capacity. Such batteries are unreliable and unsuitable for
any backup use.
PG 1000 is not designed for use with an automotive battery. Please note that an automotive battery design di󰀨ers from
that of a stationary battery. A starter battery is designed for a high-current, frequent and very short discharge during
start-up while a stationary battery is designed to be used only from time to time during a power failure but it shall stand
a long lasting discharge with a relatively low current. That is why using an automotive battery is unadvisable and such a
battery, although featuring the same capacity, will not reach the same backup time as a stationary battery.
Should the UPS be disconnected from the mains for a longer time, it is unconditionally necessary to disconnect
also the battery from the UPS. Despite being switched o󰀨 by the mains switch, UPS keeps drawing a tiny
current from the battery that might discharge it even below the critical level. Storing a discharged battery will
cause its denite destruction!

WIRING A BATTERY
Battery cables with the right terminals (lugs) shall be connected to the battery, respecting the right polarity.
Avoid applying excess power when tightening bolts at the battery (the recommended torque is 5-7 Nm). The battery
might get destroyed when the contacts tear off the lead plate inside the battery. For an improved contact, applying
anti-oxidant compound may be useful.

Connecting one battery Connecting batteries in parallel
Battery voltage shall be the same as in PG 1000.
In case of connecting more batteries in parallel, all the batteries shall be of the same nominal capacity, principally the
same model from the same manufacturer, and if possible also from the same production batch. All the batteries shall
have the same tension (equally charged). The length of connecting cables should be almost identical as well as the
ambient temperature. A su󰀩cient safe distance between batteries of at least 1.5 cm shall be respected.
The batteries should be disconnected, measured separately and charged if needed at least once a year. The batteries
may be discharging unevenly (due to internal inuences) which may a󰀨ect the overall capacity of their connection.
2 INSTALLATION
1. Make sure the power grid voltage corresponds to the voltage PG 1000 is designed for.
2. Connect the battery respecting the preceding information in these Instructions (MIND THE POLARITY, + red / - blue
or black).
3. Plug the power supply cord into the respective socket at the rear side of PG 1000 and into a wall socket. WARNING
- from the moment on the battery is being charged. At the same time, the internal cooling fan also starts running.
4. Connect your pump or another load by plugging its cable into the socket of PG 1000. 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 contact of the UPS outlet socket shall get connected to any lead of mains or any other electric wiring.
The UPS is designed for a closed circuit. If the 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 TN-S network is the protective yellow-green lead.
5. Press ON/OFF push button to turn PG 1000 on. A signal will sound and all the LEDs will ash once. The green LED
will stay lit, indicating that PG 1000 is running (standard mode, ready for backup).
6. 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 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 1000 from the mains shall be respected
