SAFE OPERATING INSTRUCTIONS
• The charger has up to 25 selectable charging profiles stored in its internal memory to charge
batteries. These profiles are specific to each manufacturer and model of battery. Your equipment
supplier or charger distributor is responsible for ensuring the active charge profile matches the
battery pack charging requirements. Contact them with any questions about which profile to
select for each battery pack.
• The charger may become hot during charging. Use hand protection to safely handle the charger
during 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. The charger also reduces output
power if it detects the battery pack is damaged.
• If power is interrupted, and then returns, the charger starts 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.
• 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 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.
- 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 Curtis Instruments for the correct
AC cord set terminating with a 3-prong plug suitable for your region's grounded power outlet.
- 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 16AWG and
rated SJT; terminated with 250V, 13A or greater connector.
- In Japan, the AC cord must be a 3-conductor PSE approved detachable AC cord set
terminated with 100V, 15A or greater connector.
- In 220-240 VAC regions, the AC cord must be a 3-conductor safety approved cord set, with
1.5mm² 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 and both plug and
connector should be rated
250V, 10A, or greater.
• Extension cords must be 3-wire
cord no longer than 30m (100') at
10 AWG or 7.5m (25') at 16 AWG,
per UL guidelines.

2.0 UNDERSTANDING THE BATTERY CHARGER
1. When you first plug the charger into AC power, the AC Power Indicator illuminates solid blue to
indicate AC power is present.
Solid blue = AC power available
2. The Battery Charging Indicator has 4 states as follows:
Flashing green = Low state of charge
Solid green = High state of charge
Flashing green = High state of charge
Solid green = Charge completed
3. The Fault/Error/USB Indicator indicates faults, errors, and USB activity as follows:
Solid red = Charger fault
See display panel for details
Flashing amber = External error condition; Caution
See display panel for details
Flashing green = USB port active
Solid green = Safe to remove USB flash drive
See the error display for the code and error description in the Charger Error & Fault Codes Table.
4. The Charging Output Indicator means that the charger output is active, and there is a potential risk
of electric shock.
5. The Charge Profile / Error Display shows one of four possible codes to indicate different conditions:
• F codes: a condition has caused charging to stop. Re-insert AC power to reset the
charger to clear the error.
• E codes: an error condition has caused charging to stop. Re-insert AC power to reset the
charger to clear the error.
• P codes: the charger profile selection is active.
• USB codes: the USB interface is active, and the USB flash drive should not be removed.
When the E, F, and P codes appear, the letter is followed by three numbers and a period to
indicate different conditions (e.g., E-0-0-4). See the Charger Error & Fault Codes Table for details on
these conditions and solutions.
6. The Select Charge Profile button is used to select a charge profile from the profiles that are stored on
the charger. Up to 25 charge profiles can be stored. See Selecting A Charge Profile for instructions.
7. The USB Host Port allows data to be transferred to and from the charger using a standard USB
flash drive, including the downloading of charge tracking data and updating of the charger's
software and / or charge profiles.
