The VETUS battery charger has a charging characteristic as shown in
par. 14.1 at page 36.
4 .1 Explanation to the charging characteristic
1 Bulk Stage (Constant Current)
At the beginning of the charging process, the flat battery is charged
at constant current (maximum charge current) until the battery volt-
age reaches the set charging voltage (See 14.3 S1-DIP switch set-
tings).
2 Absorption Stage (Constant Voltage)
The absorption charging duration will depend on the battery status.
Before moving to absorption stage, charger will wait for two minutes
then charging at constant voltage until the battery is fully charged.
Once the battery is fully charged or the charging current is below
6.25% of the rated charging current for 15 minutes, then the absorp-
tion stage ends.
3 Float Stage
After absorption stage, the battery charger switches to float stage,
maintains the battery at 100% charge without overcharging or dam-
aging the battery. This means the charger can be left connected to
the battery continuously.
4 Recondition stage
Every 12 days, the battery charger switches back to Bulk stage for
85 minutes in order to revive the battery. This prevents any fatigue
symptoms such as sulphation.

5 Installation
5 .1 Installing
Choose a dry place at considerable distance from a heat source.
High temperatures can negatively affect the capacity of the appara-
tus.
Therefore never cover the ventilation openings and keep a space of
at least 10 cm free around the battery charger.
Do not place the battery charger too far from the battery in order to
restrict the loss of voltage on the (12 volt resp. 24 volt) connection
wires as much as possible. If necessary, it is better to lengthen the
230 volt lead.
Do not place the battery charger directly above the battery; sulphur-
ous battery fumes could cause damage to the electronic parts.
The apparatus meets the protection level IP 20.
Affix the battery charger to a wall in vertical position with the con-
nections downwards, see also '15 Principal dimensions' .
Do not drill any extra fastening holes in the metal casing!
The presence of small metal particles in the battery charger can
cause irreparable damage .

Battery connections

First disconnect the mains voltage before connecting or disconnect-
ing the batteries.
The battery current must correspond with the details on the battery
charger!
Refer to the '13 Electrical circuit diagrams' to see how the battery
charger must be connected to the batteries.
Use cables of sufficient thickness and use cable sockets, see '10 Wire
size selection table' for the correct cross-section.
It is advisable to use short shielded or twisted battery cables to com-
ply with CE guidelines.
Large currents flowing through wires that are too thin, or transfer re-
sistances caused by bad connections can lead to wires or (plug) con-
nections becoming extremely hot and causing fire.
When connecting the charger to the battery observe the correct po-
larity!
