INSTALLATION INSTRUCTIONS FOR MODEL MBC8 & MBC9 BATTERY CHARGERS The Charger cabinet must be mounted in a vertical position, preferably on a wall in close proximity to the battery. The areas above and below the Charger must be clear for at least 12 inches to allow free air flow for cooling. The Charger cabinet must not be located in areas subject to falling or spraying water. The cabinet should not be subject to shock or vibration. If it is necessary to mount the unit on an engine skid, select a point subject to the least amount of shock or vibration and install suitable vibration dampers. The four mounting ears have 5/16 inch holes (or slots) to accept ^1/₄ inch bolts. The horizontal spacing is 10 inches (centers) and the vertical (center) spacing is 13¼ inches. The unit weight is less than 60 pounds. For wiring, use wire having insulation which is unaffected by the environment of the installation. For engine starting battery installations, use flexible stranded copper wire having insulation which is unaffected by oil or engine heat. The bushing supplied with the Charger are in 7/8 inch diameter holes for ¹/₂ inch nominal conduit fittings. Discard bushing(s) when conduit(s) is used. TABLE 1 - LOWER CHASSIS TERMINAL STRIP WIRING TERMINAL MINIMUM WIRE SIZE DESIGNATION GND As Required Chassis Ground-Connect to ground wire of a three prong line cord when used.
