vapours

Batteries contain acid which is harmful to the eyes and skin. During charging,
gases and vapours are released that may be harmful to health and are highly ex­plosive in certain circumstances.

Only use the charger in well-ventilated areas to prevent the accumulation of ex­plosive gases. Battery rooms are not deemed to be hazardous areas provided that
a concentration of hydrogen of less than 4% can be guaranteed by the use of nat­ural or forced ventilation.

Maintain a distance of at least 0.5 m (19.69 in.) between the battery and charger
during the charging procedure. Possible sources of ignition such as fire and na­ked flames must be kept away from the battery.

The battery connection (e.g. charging terminals) must not be disconnected for
any reason during charging.

Do not inhale any of the gases and vapours released under any circumstances ­Make sure the area is well ventilated.

To prevent short circuits, do not place any tools or conductive metals on the bat­tery.

Battery acid must not get into the eyes or onto the skin or clothes. Wear protect­ive goggles and suitable protective clothing. Rinse any acid splashes thoroughly
with clean water and seek medical advice if necessary.

General informa­tion regarding
the handling of

Safety measures
in normal opera­tion

EMC Device
Classifications

Chargers with a ground conductor must only be operated on a mains supply with
a ground conductor and a socket with a ground conductor contact. If the charger
is operated on a mains supply without a ground conductor or in a socket without
a ground conductor contact, this will be deemed gross negligence. The manufac­turer shall not be held liable for any damage arising from such usage.

Only operate the charger in accordance with the degree of protection shown on
the rating plate.

Under no circumstances operate the charger if there is any evidence of damage.

Arrange for the mains cable to be checked regularly by a qualified electrician to
ensure the ground conductor is functioning properly.

Any safety devices and parts that are not functioning properly or are in imperfect
condition must be repaired by a qualified technician before switching on the
charger.

Never bypass or disable protection devices.

After installation, an accessible mains plug is required.

Devices in emission class A:

Are only designed for use in industrial settings

-

Can cause line-bound and radiated interference in other areas

-

Devices in emission class B:

Satisfy the emissions criteria for residential and industrial areas. This is also

-

true for residential areas in which the energy is supplied from the public low­voltage mains.

EMC device classification as per the rating plate or technical data.

EMC measures In certain cases, even though a device complies with the standard limit values for

emissions, it may affect the application area for which it was designed (e.g. when
there is sensitive equipment at the same location, or if the site where the device
is installed is close to either radio or television receivers).
If this is the case, then the operating company is obliged to take appropriate ac­tion to rectify the situation.

Maintenance Before switching on, always check the mains plug and cable as well as charger

leads and charging terminals for any signs of damage.
If the surface of the device housing is dirty, clean with a soft cloth and solvent­free cleaning agent only.

Principle The main feature of the new Active Inverter Technology is intelligent charging.

This means that the charging behaviour adapts itself automatically to the age
and state of charge of the battery. This innovation extends the battery's service
life and reduces the amount of maintenance required, while at the same time im­proving efficiency.

Active Inverter Technology is based on an inverter with active rectification and an
intelligent safety cut-out. The charging current and voltage are held constant by
a digital control that is not affected by any fluctuations in the mains voltage.

Device concept The compact design reduces space requirements and makes portable use con-

siderably easier. In addition to its many existing features, the charger has a mod­ular design that makes it easy to upgrade; it is therefore ideally equipped for fu­ture requirements. A wide range of options is available. A voltage limit provides
optimum protection for the vehicle electronics.

Buffering (Trickle) mode

General informa­tion

Buffering the
battery

Buffering (Trickle) mode is intended exclusively for relieving the battery during a
vehicle diagnosis or software update. The power used over an extended period of
time must be less than the charger's maximum output current (25 A / 35 A), oth­erwise the battery will be drained. Buffering (Trickle) mode is not suitable for
fully charging the battery.

NOTE!

Danger due to a faulty battery.

This can result in damage to property.

Before buffering, ensure that the battery is fully functional.

▶

Plug in charger mains plug

1

Select Buffering mode using the up/down keys.

2

Connect the battery - the de-energised charging leads mean there are no

3

sparks when connecting to the battery, even if the charger is already connec­ted to the mains supply.

Connect the red charging lead to the positive pole (+) of the battery

-

Connect the black charging lead to the negative pole (-) of the battery

-

The charger automatically identifies
the battery, e.g. 12 V, and starts the
buffering process after 5 seconds.

If the battery voltage is not correctly
identified (e.g. in the event of a deeply
discharged battery), you have 5
seconds to enter the correct battery
voltage, as follows:

NOTE!

Danger if the wrong battery voltage is set.

This can result in damage to property.

Always ensure that the correct battery voltage is set.

▶

26

Set the correct battery voltage using the Up/Down

4

keys (6V / 12V / 24V).

Confirm the selection using the Stop/Start key

5

If the battery voltage selection window does not open, then the battery is in a
state of extreme deep-discharge (less than 2 V). In this case, buffering is not per­mitted. We recommend that the battery is replaced.

WARNING!

Danger following ignition of oxyhydrogen caused by sparks resulting from the
charging leads being disconnected too soon.

This can result in serious injury and damage to property.

Refresh mode

General informa­tion

"Refresh" mode is used to charge the 12 V starter battery if it is suspected that
the battery has been in a state of deep discharge over a long period (e.g. battery
sulphated)

Battery is charged to maximum acid density

-

Plates are reactivated (degradation of sulphate layer)

-

WARNING!

Danger from overheated battery.

This can result in serious injury and damage to property.

Batteries must be supervised during the charging process.

▶

Monitor the battery temperature and interrupt the charging process if neces-

▶

sary.
Do not reactivate the battery in an ambient temperature of over 30 °C (86

▶

°F).
"Refresh" mode can cause the battery to reach temperatures of up to 45 °C

▶

(113 °F).
Immediately switch off the charger if the battery temperature exceeds 45 °C

▶

(113 °F).

NOTE!

Danger from "Refresh" charging on an installed vehicle battery connected to
the vehicle power supply.

This can result in damage to the vehicle electronics.

Disconnect the battery from the vehicle power supply and remove it from

▶

the vehicle before carrying out refresh charging.

The success of refresh charging depends on the degree of sulphation of the bat­tery.

NOTE!

Danger from improper use of the "Refresh" charging function.

The battery may become damaged due to water loss or drying as a result. Make
sure that

the battery is at ambient temperature (20 - 25 °C) (68 °F - 77 °F).

▶

the battery capacity has been correctly set.

▶

the battery has been disconnected from the vehicle power supply.

▶

"Refresh" charging is carried out on batteries removed from the vehicle,

▶

either in the open (without being exposed to direct sunlight) or in well-ventil­ated areas.

CAUTION!

Reactivating bat­teries

Danger from battery acid.

This can result in personal injury.

Wear eye protection and suitable protective clothing when handling battery

▶

acid.
Rinse any acid splashes immediately and thoroughly with clean water.

▶

Seek medical attention if necessary.

▶

Do not inhale any of the gases and vapours released under any circum-

▶

stances.

Refresh mode may be used on the following batteries:

Wet batteries:

-

sealed batteries with a liquid electrolyte (identifiable on the vent plugs)
After reactivating, check the acid level and top up with distilled water if ne­cessary.
Absorbent Glass Mat (AGM) batteries:

-

sealed batteries (VRLA) with immobilised electrolyte (sealant) and mainten­ance-free wet batteries (MF)

NOTE!

Danger of deep-discharged batteries freezing at 0 °C (32 °F).

A frozen battery can become damaged.

Before starting refresh charging, ensure that the acid in the battery to be re-

▶

freshed is not frozen.
