User’s Manual
DC Output
A DC output issue exists. Ensure that the charger DC fuse on the user interface is not blown. Otherwise,
the charger is not functioning properly. It is possible that the charger is still able to charge, but with reduced
current.
Jumper Missing
The internal charge profile jumper is missing. See Section 4 for details.
11. LOCKOUT/INTERLOCK RELAY OPTION
On-board X-Series chargers can be ordered with an optional internal relay that can be used to provide
lockout/interlock functionality. The two (2) exposed terminals of the dry-contact relay are CONNECTED when AC
power is NOT PRESENT at the charger, and the terminals are DISCONNECTED when AC power IS PRESENT
at the charger. The relay is rated for up to 10 amps.
12. MAINTENANCE
WARNING: DISCONNECT BOTH AC AND DC POWER FROM THE CHARGER BEFORE PERFORMING
ANY MAINTENANCE. CONTACT WITH LIVE COMPONENTS WITHIN THE CHARGER COULD CAUSE
ELECTRICAL SHOCK, SERIOUS INJURY, OR DEATH.
CAUTION: KEEP CHARGER CLEAN AND DRY, INSIDE AND OUT. FAILURE TO DO SO MAY CAUSE
DAMAGE OR FAILURE OF CHARGER.
The charger requires minimal maintenance. It should be kept clean. Twice a year, or as often as the cleanliness
of the area may dictate, the interior of the charger should be thoroughly blown clean with dry compressed air.
The components of the charger are cooled by natural convection. If dust and debris are allowed to build up, they
will restrict airflow and could cause components to overheat.
Always be careful not to bump wiring or
components. This could cause loose connections and failures.
Moisture may cause electrical shorting and/or corrosion. It may also combine with dust and debris making them
more difficult to remove. Do not use liquids to clean the charger. Liquids could cause damage. Compressed air
should be used to clean dust and debris from the charger and its components.
12.1 Check Charger Area
The area around the charger must remain clean, cool, dry, and well ventilated. Check for obstructions to
airflow, clearances, or other violations of the requirements in Section 5.
12.2 Visual Inspections
Check the charger for any physical failures, such as loose contacts or hardware, excess wear, or damage.
Darkened or hot terminals should be tightened or replaced.
12.3 Battery Conditions
CAUTION: CHECK THE DC CONNECTIONS FROM THE CHARGER TO THE BATTERY AND MAKE
SURE THEY ARE TIGHT AND CLEAN. TIGHTEN AND/OR CLEAN IF NEEDED. FAILURE TO DO SO
COULD CAUSE MALFUNCTION, FIRE, OR EXPLOSION.
Batteries must be well maintained for the charging system to operate properly. Follow battery manufacturer
instructions for battery maintenance. Check for loose connections or corrosion.
DC connections may become corroded over time. If the connections become corroded, they should be
cleaned as recommended by the battery manufacturer. After the connections have been cleaned, a battery
connection treatment should be applied to help prevent corrosion from reoccurring. Contact the battery
manufacturer for their recommendations.
Periodic cleaning and watering of non-sealed batteries is very important. Logging the water usage of non-
sealed batteries is useful. As a battery ages, it will use more water.
