SAFE OPERATING INSTRUCTIONS
•
The charger contains up to 25 selectable charging algorithms stored in its internal memory to charge batteries.
These algorithms are specific to each manufacturer and model of battery. Your equipment supplier or charger
distributor is responsible for ensuring the active charge algorithm matches the battery pack charging
requirements. Contact them with any questions about which algorithm to select for each battery pack.
•
The charger may become hot during charging. Use hand protection to safely handle the charger when
charging.
•
To maintain safe operations, the unit automatically reduces its output power if the temperature rises above set
thresholds, or if the AC input voltage is too low.
•
If power is interrupted, and then returns, the charger restarts and continues to operate without hazard to the
user, or damage to the batteries.
•
Unplug the charger from both AC and DC sources when cleaning, moving, or conducting any maintenance or
repair on the charger. No user serviceable parts are inside. Do not remove the cover due to the risk of electrical
shock.
•
Do not expose the charger to oil, dirt, mud, or direct heavy water spray when cleaning the vehicle or
machine.
•
All connectors between the battery charger and the battery should be regularly inspected for corrosion
and contamination as these can cause overheating and can be a fire hazard.
•
If the detachable AC input power cord set or DC output cord is damaged, do not use the charger until they are
replaced with cord sets appropriate to your region and application.
•
When mated with a Delta-Q Technologies sealed AC cord, the charger meets IP66 specifications, making it
dust-tight and protected against powerful water jets. If a cord set with an unsealed connector is used, the plug
and connector must be periodically inspected to ensure the contacts are clean and dry.
o
If this charger is provided with an AC cord set and
the power plug does not match the power outlet,
contact the equipment manufacturer, distributor,
or Delta-Q Technologies for the correct AC cord set
terminating with a 3-prong plug suitable for your
region’s
grounded power outlet.
o
In North America (and other 120V AC regions), the
AC cord must be a 3-conductor UL Listed/ CSA
approved detachable cord set at least 1.8m in length
(≥ 6 feet), minimum
16 AWG and rated SJT; rated
105
˚
C min, and terminated with 125V, 13A, or greater connector.
o
In Japan, the AC cord must be a 3-conductor PSE approved detachable AC cord set,
rated 105˚C,
and
terminated with 100V, 15A, or greater connector.
o
In 220-240VAC regions, the AC cord must be a 3-conductor safety-approved cord set, with 1.0mm²
conductors (min.), rated appropriately for industrial use. The cord must be terminated on one end with a
grounding type input plug appropriate for use in the country of destination; both plug and connector should
be rated 250V, 10A, or greater.
•
Extension cords must be 3-wire cords no longer than 30m
(100’)
at 10 AWG or 7.5m
(25’)
at 16 AWG, per UL
guidelines.
