Safety - Section 22 8/11 OM2221 Page 22-2 BATTERIES This decal is placed on the exterior of the battery box and near the battery disconnect switches to indicate that the battery system (24VDC) is a negative (-) ground system. Attached to the exterior of the battery box is a danger decal which stresses the need to keep from making any sparks near the battery. When another battery or 24VDC power source is used for auxiliary power, all switches must be OFF before making any connections. When connecting auxiliary power cables, positively maintain correct polarity. Connect the positive (+) posts together and then connect the negative (-) lead of the auxiliary power cable to a good frame ground.
Do not connect to the negative posts of the truck battery or near the battery box. This hookup completes the circuit but minimizes the danger of sparks near the batteries. These decals are placed above the battery disconnect switches on the side of the battery box to indicate OFF and ON positions of the switches. Sulfuric acid is corrosive and toxic. Use proper safety gear, goggles, rubber gloves and a rubber apron when handling and servicing batteries. If sulfuric acid is swallowed, gets into your eyes or contacts your skin, get proper medical help immediately. HIGH VOLTAGE A high voltage danger plate is attached to the access door of the rear axle housing. High voltage may be present!
Only authorized personnel should access this rear housing. This decal is also attached to the exterior of the battery box. It details the correct procedure for disconnecting the battery cables from the batteries.
