- Do not expose the system to rain, snow, or liquids of any type. Do not disassemble the system; call Chadha Power’s authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.
- To reduce the 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 THE 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 a 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 of time, so they should periodically be recharged even if they are not being used.
- GROUNDING INSTRUCTIONS: The Chadha Power Inverter 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 your 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 the eyes, immediately flood the eyes with running cool water for at least 15 minutes and get medical attention immediately.
- Never attempt to charge a frozen battery.
- Before touching battery terminals 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 the 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 your eyes.
