Installation Instructions
WARNING：
The output of chargers with greater than 48V may pose an energy and/or shock hazard under
normal use. These units must be installed in the host equipment in such a manner that the
output cable and battery connections are only accessible with the use of a tool by qualified
personnel.
1) Determine Mounting location:
While its sealed nature allows the charger to be mounted virtually anywhere, the choice of
mounting location and orientation is extremely important. For optimum performance and shortest
charge times, mount the charger in an area with adequate ventilation. The charger should also be
mounted in an area that will be relatively free of oil, dirt, mud, or dust since accumulations within
the fins of the charger will reduce their heat-dissipating qualities. Optimal cooling also occurs when
the charger is mounted on a horizontal surface with the fins vertical. More airflow from below the
charger will help cool the fins, so mounting above open areas or areas with cut-outs for airflow is
desirable. Contact Delta-Q for information on other mounting orientations. As the charger may get
hot I operation, the charger must be installed such that risk of contact by people is reduced. The
charger’s AC plug must be located at least 18’’ above the floor/ground surface and the status
display must be visible to the user.
2) Mounting Procedure:
Mount the charger by the mounting plate using appropriate fasteners (i.e.1/4’’ or M6 with locking
hardware).For UL2202 compliance, a 12 AWG green bonding wire with ring terminals must be
attached from the bonding stud located on the front of the charger (identified by) to the vehicle
frame. The vehicle connection must be made using corrosion resistant hardware (e.g., a #
10stainless steel machine screw with at least two threads of engagement and, if required, a paint
piercing washer).
3) DC Battery Connection Procedure:
a) The green wire outputs battery voltage when the charger is not plugged into AC to provide an
interlock function—see fig.1. If used, a user-supplied 1 A fast-blow external fuse must be
installed inline to prevent damage. Shorting or drawing more than 1 A may damage charger and
