Choosing the Mounting Location for the Minn Kota 210D
Do not mount the MK210D charger above batteries as lead-acid batteries give off corrosive gasses which will damage the charger over time. Never allow battery acid to drip on the charger when reading electrolyte specific gravity or filling battery. Also, as with most electrical devices, do not mount the Minn Kota MK210D charger below the waterline of the boat or directly adjacent to fuel tanks.
Each DC output cord is 6 feet long. Make sure that all DC output cords can reach the batteries and that the AC power cord can reach a power source. When using an extension cord, make the AC connection to the MK210D charger outside of the battery compartment as far away as practical to reduce the risk of a spark igniting gasses in the compartment. Each output cord is equipped with a temperature sensor.
By monitoring external temperature, the Minn Kota battery charger adjusts the charging profile of the battery to assure full charge without overcharging or undercharging the battery. Attempting to lengthen or shorten the output wires could damage the temperature sensor and affect the charger output. If the DC battery leads are not long enough, they may be lengthened by splicing and soldering 12 AWG (minimum) wire. Each splice should be covered with dual wall adhesive lined heat shrink tubing to protect the joint from corroding. The splice should be made between the fork in the output cable and the fuse holder. The fuse holder should always remain within 7” of the battery terminals. The maximum extension length is 15 feet.
You may contact the Minn Kota Service Department with any questions. Do not splice the AC power cord, as this voids the three year Limited Warranty. Even though the Minn Kota MK210D charger is capable of operating in a high ambient temperature environment, a minimum of 6 inches of unobstructed area should be allowed on all sides of the unit for proper air circulation and cooling. Proper cooling and circulation will allow the charger to operate at peak efficiency.
Mounting the Minn Kota MK210D
Due to the weight of the charger and the pounding that boats routinely endure, take the time to securely mount the MK210D charger to prevent damage. Mounting with bolts, nuts, and washers is preferable to mounting with screws. Use the largest diameter bolts possible, and use all four mounting holes. Your Minn Kota MK210D battery charger is supplied with an AC plug holder designed to hold the power cord plug when not in use. Mount the AC plug holder with four screws in a convenient dry site to prevent corrosion to the AC plug and to prevent the AC plug from making contact with the battery posts.
