Rear Panel

Chadha Power GQP Inverters have two battery wires coming out from the rear side, a Thermal Circuit Breaker of 7/10Amp, (7Amp for 650VA, 850VA & 1050VA and 10Amp for 24V 1450VA), AC output socket and a power cord to connect with mains supply. Red coloured battery wire is to be connected to positive terminal of battery and black coloured wire to be connected to negative terminal of the battery.
Caution: Do not reverse the battery connections, it will blow the DC fuse connected in series with battery connection inside the Power Card

Some Safety Measures

Important Precautions

The output side of the AC wiring of CHADHA POWER Inverterz should never be connected to utility power or a DG set. This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until connections are made. Installation should ensure that the AC output of CHADHA POWER Inverterz should not be connected to AC input.

Note: Connecting the battery cables to the CHADHA POWER Inverterz battery terminals may cause spark, usually accompanied by a “snap”. This is normal, don’t let it scare you.
Never disconnect battery cables while the CHADHA POWER Inverterz is delivering power or battery charger is operating. Always turn the switch off first.

General Precautions

Before installing, connecting any wiring or using the CHADHA POWER Inverterz, read all instructions of this instruction manual.
CAUTION: To reduce risk of injury, use only deep-cycle lead acid batteries.
Do not expose the system to rain, snow or liquids of any type. Do not disassemble the system; call CHADHA POWER authorized service centre when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.
To reduce risk of electric shock, disconnect all the wiring from the system before attempting any maintenance cleaning. Turning off the system will not reduce this risk
WARNING: WORKING IN VICINITY OF A LEAD ACID BATTERY IS DANGEROUS.
Be extra cautious when working with metal tools on, or around batteries. The potential exists to drop a tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an explosion
Do not leave batteries in discharged state for more than a day or two. They will undergo a chemical process called sulfation which can permanently damage the battery. Also batteries will self-discharge over a period time, so they should periodically be recharged even if they are not being used.
GROUNDING INSTRUCTIONS: The CHADHA POWER Inverterz Sine Wave should be connected to a grounded, permanent wiring system.

Personal Precautions

Someone should be in your audible range to come to your aid when you work near batteries.
Have plenty of fresh water nearby in case battery acid contacts skin, clothing or eyes
Wear complete eye protection and clothing protection. Avoid touching eyes while working near batteries. Wash hands when done.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eyes, immediately flood eyes with running cool water for at least 15minutes and get medical attention immediately.
Never attempt to charge a frozen battery.
Before touching battery terminal make sure that the system is OFF and AC mains to the CHADHA POWER Inverter is also OFF.
NEVER smoke or allow spark or flame in vicinity of the batteries.
Remove personal metal items such as rings, bracelets, necklaces and watches when working with an electrical circuit. These items can cause a short circuit current high enough to weld a ring and may cause severe burns
If it is necessary to remove any battery, always remove the grounded terminal from the battery first. Make sure all the accessories are off, so as not to cause arcing. Be sure that the area around the battery is well ventilated.
Clean battery terminals. Be careful not to allow corrosion to come in contact with eyes.
Study all battery manufacturers’ specific precautions and recommended rate of charge
Add only distilled water in each cell until battery acid reaches level specified by the battery manufacturer. This helps purge excess gas from cells. Do not over fill. For a battery without caps, carefully follow manufacturer’s charging instructions.
CAUTION: The CHADHA POWER INVERTERZ Pure Sine Wave should be connected to grounded, permanent wire system.

SPECIAL NOTICES:

The Chadha Power GQP Inverterz are for use with a nominal supply voltage of 12V/ 24V DC.
NoAC or DC disconnects are provided as an integral part of this system.
No over current protection for the battery supply is provided as an integral part of this system. Both AC & DC disconnects must be provided as part of the system installation.
No over current protection for the AC output wiring is provided as an integral part of the system. Over current protection of the AC output wiring shall be provided as part of the system installation.

Installation

Where to install

The system should be installed in a location that meets the following requirements :

a) Dry — Do not allow water to drip or splash on the Chadha Power Inverterz
b) Cool —- The ambient air temperature around the system should be between 0 degC to 45 degC (32 degF to 113 degF). Cooler environment is better for the system.
c) Ventilation : Allow at least two inches (5cm) of clearance around the system for air flow.
d) Safe: Do not install the Chadha Power Inverterz in the same compartment as batteries or in any compartment which is storing flammable liquids such as gasoline.
e) Close to battery – Install the system as close to the battery as possible in order to minimise the length of cable required to connect the system to the battery. It is better and cheaper to run longer AC wires than longer DC cables.

CAUTIONS! To prevent fire, do not cover or obstruct ventilation openings. Do not install the system in a Zero – clearance compartment. Overheating may result.

WARNING! This equipment contains components which tend to produce arcs or sparks. To prevent fire or explosion do not install in compartment containing batteries or flammable materials or in locations which require ignition protected equipment.

How to Install

Ensure that the ON/OFF switch on the front panel of the Inverter is in OFF position before you begin the installation
Connect the negative terminal of the battery to the thick black wire of system
Connect the positive terminal of the battery to the thick red wire of system

AC Cabling:
Plug in the power cord to the mains socket on the wall. The cabling should have proper earthing. Input supply should remain ON once the system is installed. Take output from output socket.

Start Operation

Once the AC and DC wiring have been installed and connected, take a moment to go re-examine all the connections and make sure they are secured and in the proper terminals.

Check to see that the CHADHA POWER Inverter is turned off and then apply battery (DC) power to it. Ensure that all wiring has been installed properly. Next turn On the battery bank DC disconnects or connect the proper fuse in line to the battery to compete the battery circuit.
Put ON/OFF switch to the ON position. This system should run a load without AC input (battery only). Place a load on the system and make sure it works.
To charge your batteries connect AC power to the system by plugging in the AC power and turning on the mains line. This shows that charger is working properly. Any AC load powered by the system should also work at this point since a portion of the AC power is passed through this CHADHA POWER Inverter to power the loads.
Disconnect the AC power, the system should transfer to battery mode immediately. This will be indicated by clicking sound as the internal transfer relay changes position
The system will begin to take power from the batteries and use it to power the load. And the load continues to operate uninterrupted.

The above steps will complete the functional test of the CHADHA POWER Inverter. If all areas pass, the system is ready for use. If something fails figure out the reason before proceeding or contact the service centre
Note: Manual / Bypass switch selection should be in manual mode. If the inverter is faulty, then select Bypass mode.

Maintenance

Very little maintenance is required to keep your CHADHA POWER operating properly. You should clean the exterior of the unit periodic a damp cloth to prevent accumulation of dust and dirt.
