Forced float
For industrial applications only.
Gel/wet battery
By removing this jumper the output will be a constant
"trickle charge" voltage of 13,8V.
Diode compensation
By removing this jumper the output voltage will be increased
with 0,7 Volt.
6 OPERATION
1 Check if the charger is „OFF".
2 Connect DC output with batteries or place fuse.
3 Switch on AC source.
Switching on:
The MASS charger will be switched on by the ON switch.
One of the front LEDS will light up now and the charging
starts immediately.

7 USING THE CHARGER WITH YOUR

BATTERIES

CHARGING EFFICIENCY
For a good performance your batteries should not be
discharged below 30-40% of their capacity. Therefore al-
ways start charging at this level.
As in marine and mobile systems often a limited charging
time is desired, batteries are with generator use charged
up to 85-90%. Charging up to 100% would take too long.
This means that normally about 50% of the theoretical
battery capacity can be used.
In case a mains connection is present, charging time is
less important. Then charging up to 100% is advised.
TIPS TO INCREASE THE BATTERY LIFETIME:
• Install the batteries at a cool place. The acid in the bat-
teries will damage the plates in a high temperature en-
vironment. A normal life time of 5 year at 20°C, will go
down to 2.5 years at 30°C.
• Charge the battery immediately after a consistent deep
discharge.Especially at high environment temperatures,
sulfating occurs very fast. If the state of sulfating is not
too bad, the battery will regain a part of its capacity af-
ter a number of charge/recharge cycles.
