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 all the VANN-Guard Models. 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 any Vanner VANN-Guard. 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 VANN-Guard and the power source
(battery). 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 18of the battery. See Wire and Fuse Sizing Chart on
page 10 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
Mounting Location The VANN-Guard may be mounted in any orientation, on a flat mounting surface
suitable to support the VANN-Guard during application. Do not mount in zero-clearance compartment that
may result in the VANN-Guard overheating. Locate so that contact by people is unlikely.
Environmental Protection Your VANN-Guard has been designed to withstand direct exposure to rain
and moisture. The VANN-Guard has also been tested for exposure to direct pressure spray, but continual
exposure to direct pressure spraying may reduce the VANN-Guard serviceable life. Any damage due to
water contamination is covered by Vanner only through the terms of our factory warranty.
Wiring Sequence The VANN-Guard is internally protected for reverse polarity. The wiring sequence is
not an issue with the VANN-Guard products.
Strain Relief The VANN-Guard has an integral strain relief. The VANN-Guard 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.
