Summary

Safety Instructions

General

Read documentation, follow safety signs and directions before use. Equipment for designated application only.

Installation

Follow installation instructions, ensure proper grounding, check voltage conformity, and use in suitable environment.

Transport and storage

Disconnect cables, use original packaging, store in dry environment (-20 to 60°C).

Installation and wiring

Installation

Mount in dry, ventilated area. Wall or floor mount. Ensure free airflow at the back for cooling.

Connecting the main battery

Ensure correct battery type setting. Check cable cross-section requirements for length.

Main battery connection sequence

Steps for connecting main battery cables: disconnect mains, disconnect battery, access terminals, connect cables.

Main battery disconnection sequence

Steps for disconnecting main battery: disconnect mains, disconnect battery, access terminals, disconnect cables.

Connecting the starter battery

Connect starter battery with 1.5 mm² wire. Not protected against reverse polarity.

VE.Can connection

Connectors for parallel operation and remote control via CAN interface.

Synchronised parallel operation

Synchronize up to 10 chargers via RJ45 UTP cables for identical settings and simultaneous state changes.

Input/shore current limit

Limit AC input current to 10.5 A max, adjustable via CCGX or remote panel.

User relay, external sense and remote shut down

Wiring for signals like user relay, external voltage/temperature sense, and remote shut down.

External voltage sense

Connect voltage sense to battery poles for accurate voltage sensing with long cables.

External temperature sense

Connect temperature sensor for temperature-compensated charging. Sensor is electrically isolated.

Remote shut down

Use remote input to shut down or turn on the charger. Connect to BMS for lithium batteries.

User relay connections

User relay triggered by battery under-voltage (<11.8 V). Can be used for generator start or alarm.

Connecting the mains

Connect mains earth, neutral, and line cables to the AC input connector, ensuring battery is connected first.

Control and Adjustment

Monitor menu

Monitor battery voltage, current, temperature, and mains current on the display.

Setup menu

Enter setup menu via 'SETUP' button for three seconds to configure charger settings.

Battery selection

Select the correct charge algorithm based on battery type (Gel, AGM, LiFePo4, etc.).

Power supply mode

Operate as a DC power supply with adjustable voltage and maximum output current.

Temperature compensation (dV/dT)

Connect temperature sensor for compensated charging. Applies to all charge states.

Power Control - maximum use of limited shore current

Set a maximum mains current to avoid fuse interruption in the supply.

Operation

Battery charging

Display shows firmware version and actual state after applying mains power.

Seven stage charge curve for lead-acid batteries

Details the voltage and current states during Bulk, Absorption, Float, and Storage phases.

Bulk

Constant current applied until gassing voltage is reached (14.4 V / 18.8 V).

Battery Safe

Limits voltage increase rate to prevent excessive gassing when absorption voltage is set high.

Absorption

Constant voltage mode after absorption voltage is reached. Time depends on bulk time.

Automatic equalization

Second voltage-limited constant current period to charge VRLA batteries fully.

Float

Output voltage reduced to storage level to limit water loss and plate corrosion.

Storage

Output voltage reduced to storage level to limit water loss and plate corrosion.

Weekly battery 'refresh'

Enters Repeated Absorption-mode for one hour weekly to fully charge the battery.

Four stage charge curve for Lithium Iron Phosphate (LiFePo4) batteries

Details the charge curve for LiFePo4 batteries.

Bulk

Constant current applied until absorption voltage is reached (14.2 V / 28.4 V).

Absorption

Constant voltage mode after absorption voltage is reached. Recommended time is 2 hours.

Storage

Output voltage reduced to storage level to maximize service life.

Weekly battery 'refresh'

Enters Repeated Absorption-mode for one hour weekly to fully charge the battery.
