Battery Placement and Wiring

Proper installation and wiring of the batteries are critical to the long-term backup capability of any power
supply system. Gelled electrolyte, valve regulated, or AGM batteries are recommended for use in DOT/ITS
power supply applications. All batteries should be tested and fully charged prior to installation. Intercon-
necting wiring must be no smaller than 8 mm² in area or 8 AWG. Longer run times and improved efficiency
may be realized using battery wiring of 13 mm² in area or 6 AWG.
In light of the specialized handling and connection requirements for batteries, only trained personnel
should install batteries in an enclosure. Personnel must always employ appropriate safety equipment
(goggles or face shields, insulated gloves, etc.) and only use fully insulated tools for tightening hardware on
the battery terminals. Additionally, proper lifting tools and techniques must always be used during battery
installation to avoid personal injury or equipment damage.
