Explosive gas precautions
1. This equipment contains components which tend to produce arcs or sparks.
To prevent fire or explosion, do not install the DR Inverter/Charger in
compartments containing batteries or flammable materials, or in locations
that require ignition-protected equipment. This includes any space containing
gasoline-powered machinery, fuel tanks, as well as joints, fittings, or other
connections between components of the fuel system.
2. To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and the manufacturer of the equipment
in which the battery is installed.
WARNING Fire Hazard:
Do not install 120 volt AC stand-alone inverters onto 120/240 volt AC multi-branch
circuit wiring. This could pose a fire hazard due to an overloaded neutral return wire in
this configuration. See “Multi-wire Branch Circuit Wiring” on page C–1 for details.
WARNING: Explosion Hazard
Working in the vicinity of lead-acid batteries is dangerous. Batteries generate
explosive gases during normal operation. Therefore, you must read this guide and
follow the instructions exactly before installing or using your DR Inverter/
Charger.
