Installation Instructions
Do not exceed the specified torque of 120 in-lbs. when connecting cables to the terminal posts ( 24,
GND, 12) during installation of the equalizer. Torque values higher than specified may damage the
product, reduce performance, and/or create hazardous conditions. Products damaged by improper torque
are not covered by the warranty.
Do not connect more than one conductor per terminal post on the equalizer. Multiple wires and
cables may overstress internal components, resulting in poor performance or creating hazardous
conditions. Products damaged by the installation of multiple conductors per post are not covered by the
warranty.
Fault protection devices must be installed between the equalizer and the power source (batter ). A
fault protection device would be any fuse or circuit breaker properly rated for the maximum DC current
obtainable. This advisory is in accordance with SAE, NEC and UL, for mobile power applications. Install
per applicable codes or within 18” of the battery. See Wire and Fuse Sizing Chart on page 9 of this
manual or contact Vanner at 1-800-227-6937 or pwrsales@vanner.com if assistance is needed in sizing
fault protection devices.
Caution: This equipment tends to produce arcs and sparks during installation To prevent fire or
explosion, compartments containing batteries or flammable materials must be properly ventilated Safety
goggles should always be worn when working near batteries
Mountin Location: The equalizer may be mounted in any orientation, on a flat mounting surface
suitable to support the equalizer during operation Do not mount in zero-clearance compartment that may
result in the equalizer overheating Locate so that contact by people is unlikely
Environmental Protection: The equalizer has been designed to withstand direct exposure to rain and
moisture The has also been tested for exposure to direct pressure spray, (IP68 rating)
Reverse Polarity Protection and Wirin Sequence: The equalizer is internally protected against
reverse polarity If the 24v, 12v and GND wires are connected to the equalizer incorrectly, the equalizer
will not be damaged and will do nothing The wiring sequence is not an issue The wiring sequence is not
an issue It does not matter which wire is connected first, second or last
Strain Relief: The equalizer has an integral strain relief that installs onto the front of the unit The
equalizer is designed with wells for the lug to sit into to resist bolt loosening from cable movement, and
the strain relief is designed to further inhibit cable movement The diagram below shows the proper
orientation for the attachment of the strain relief and the #10-32 mounting hardware that is supplied
