Charging a battery grounded to the positive terminal: Positive grounded vehicle
Charger connection.
1. Connect negative charger clip (black) to negative battery terminal.
2. Connect positive charger clip (red) to a good metal engine ground away from
the battery. Do not connect clip to fuel lines or sheet-metal body parts.
3. Connect the AC cord to the socket. The red alarm indication light will indicate a
battery which is connected to reverse polarity.
Connecting the MULTI US 3300 to an out of vehicle battery:
a)
Check polarity of battery terminals. POSITIVE (POS, P, +) battery post usually has
larger diameter than NEGATIVE (NEG, N, -) post.
b)
Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) battery post.
c)
Connect NEGATIVE (Black) charger clip to NEGATIVE (NEG, N, -) battery post.
The red alarm indication light will indicate a battery, which is connected to reverse
polarity.
d)
Connect charger’s AC cord to socket.
e)
Do not face the battery when making the final connection.
f)
When disconnecting charger, disconnect in reverse sequence from connecting
procedure. See operating instructions for charge information.
Starting the charging process
1.
Set the correct charge mode by pressing the mode button. You can find out how to
select the correct charge mode to be used for charging your battery in the section on
“SETTINGS”.
2.
Once you have established that the battery cable has been correctly connected you
can start the charging process. To do so, insert the charger plug into the AC socket.
3.
Now either the charge indicator or the maintenance charge indicator lights
up. When the maintenance charge indicator lights up, the battery is fully charged. If the
battery voltage drops, the charger sends a pulse to the battery. The length of the pulse
depends on how much charge the battery has lost. The MULTI US 3300 may be con-
nected for months at a time. However it is recommended to monitor batteries on charge.
4.
If nothing happens: If the indicator for the set voltage is still illuminated, but no other
indicator is illuminated, the connection to the battery or the chassis could be faulty, or the
battery could be defective. If the charging process has not started, this could be due to
the fact that the power socket is not supplying a current.
5.
The charging process can be interrupted at any time. In addition pull the plug of the
charger out of the power socket or put the charger on Stand-by/Power On . Always
remove the plug of the charger from the power socket before disconnecting the battery
cable. If you interrupt the charging process of a battery fitted in a vehicle, the battery
cable must always be first disconnected from the chassis and then from the other battery
cable.
