The optional charger Single-LED display, if included, would be located on the front panel, near the key-switch.
1) Do not expose charger to oil, mud or direct heavy water spray when cleaning vehicle.
2) If the detachable input power supply cord set is damaged, replace with a cord that is:
a. For North America – UL or CSA listed/approved detachable cord, 3 conductor, 16AWG minimum, and rated SJT;
terminating in a grounding type IEC 60320 C14 plug rated 250V, 13A minimum; or
b. For all other countries – a safety approved detachable cord, 3 conductor, 1.5mm 2
minimum, rated appropriately
for industrial use. The cord set must terminate on one end with a grounding type input connector appropriate for
use in the country of destination and, on the other end, an output grounding type IEC 60320 C14 plug.
3) The enclosure of the charger has been tested successfully to EN60529, meeting IP66. The AC supply inlet is rated to
IP20, which is suitable for indoor use only. Keep all AC connections clean and dry.
If a fault occurs, count the number of red flashes between pauses and refer to the following table:
Red Flashes Cause Solution
Battery High Voltage Check battery size and condition and reset charger
(interrupt AC power for 15 seconds).
Battery High Voltage Check battery size and condition and reset charger
(interrupt AC power for 15 seconds).
Charge Timeout caused by battery
pack not reaching required voltage.
Charger output was reduced due to
high temperatures. Check connections.
Operate charger at a lower ambient temperature.
Check Battery: Battery could not
be trickle charged up to minimum
voltage Check for shorted or damaged cells.
Over-Temperature: Charger shut
down due to high internal
temperature. Ensure sufficient cooling air flow and reset charger
(interrupt AC power for 15 seconds).
Charger Internal Fault Reset charger (interrupt AC power for 15 seconds). If
fault persists, likely needs to be replaced.
