geTTing sTarTed 1. Connect the charger’s red cable clamp to the battery’s positive terminal post (+), and the black cable clamp to the battery’s negative terminal post (-). 2. Connect the charger’s mains plug to a grounded power socket. 3. Select the correct function by pressing the “Mode”-button. Charging: • Choose voltage: 12 V or 24 V • Choose battery technology: Standard or AGM/Gel... - Page 4 informaTion • WSC720 is a powerful charger for service stations. • WSC720 can be used for: 1. As a battery charger for 12 V and 24 V batteries 2. To maintain voltage in 12 V and 24 V systems 3. As Power Supply for 12 V system • In charge modes (12 V and 24 V) WSC720 will initially charge the battery, and then, with a constant current charging (float charge) as long as it is connected, maintain full charge. • In the charge modes (12 V and 24 V), WSC720 will also maintain system voltage, functioning as a Diagnostic Power Supply, giving up to 70 A. • In ”13,7 V Power Supply” WSC 720 will act as a Power Supply for 12V equipment. This mode will give a current up to 70 A useful as: - Power Supply at replacement of 12 V batteries - Power Supply in 12 V systems - Power Supply for diagnosis • WSC720 is equipped with a temperature compensator, which will give best possible charging independently of temperature.

The position of the cables, see page 11. 3. Connect mains plug to an earthed power socket. 4. If the cables are incorrectly connected, or if wrong system volta- ge (12 V or 24 V) is chosen, the red LED will illuminate to indicate a fault. If so, check the connection and adjust accordingly. 5.
- Page 6 6. The LED will show a constant yellow until the charge is complete, then the LED changes from yellow to green. 7. When charging is complete first the mains plug should be removed and then the cable clamps. 8. If the cables are left in place there will be a continual maintenance of charge at 13,7 V, otherwise stop the charging according to the instruction.

Page 7: Safety Instructions
safeTy insTrucTions • WSC720 has been constructed to charge 12 V lead acid batteries or to act as a power supply for 12 V equipment. Do not use the charger for other purposes. • WSC720 is constructed for indoor purpose and must be protected from moisture. • Do not use WSC720 if its cables, terminal clamps or casing are damaged. • Batteries emit explosive gases while they are charging. It is therefore important to ensure good ventilation and avoid sparks and naked flames in the vicinity of the battery. • Be careful and avoid metallic contact between the clamps. - Page 8 funcTions: • WSC720 must be connected to the battery as described in the User Guide. After it is connected, it will charge the battery and maintain it fully charged with constant voltage charging (float charge) as long as it is connected to the mains power. • Don’t keep WSC720 connected to the battery without mains connected. This will in the long term discharge the battery. • WSC720 is fully automatic and is programmed for advanced charging of lead-acid batteries between 40 and 500 Ah. • If the 24 V mode is selected, the battery voltage must be higher than 15.8 V. If not, the red LED will indicate a fault.

equipment drawing current (parallel loads) being connected to the battery during charging. • Batteries will be damaged when charged at high temperatures. For this reason, WSC720 features a safety function that terminates charging when the temperature is too high, approx. 50°C. This is shown by the LED shining a constant red. faulT indicaTions and Trouble shooTing Fault: The red LED lights when the charger cables are connected to the battery terminals. - Page 10 Fault: Charging does not start, i.e. the lamp continues to shine, and the yellow LED does not change to the steady yellow light. Probable cause: The battery voltage is too low, less than 7 V, to start the charger. This may be because the battery is worn or faulty or has been completely discharged.
