Please read the mounting instructions and operating manual completely prior to starting
connection and start-up.
The VOTRONIC Battery Protector 40 had been designed for campers, boats and intervention vehicles and is inserted
between battery and consumers. It protects the battery from dangerous total discharge and the consumers from low
voltage and overvoltage.
The reset to normal operation is effected automatically, as soon as there is an increase of the voltage to 12.5 V due to
battery recovery or short-time charging. Manual cancelling of the disconnection is also possible by means of the
function
“EMERGENCY ON”
.
Remote control
of the Battery Protector 40 is possible by means of the terminal ""
and a simple switch
(single-
pole ON / OFF). By this, it is becoming an
efficient battery main switch
.
Also the EMERGENCY-ON function can be remote-controlled.
The range of application extends to mission vehicles, campers, boats and solar systems:
Suitable for any type and brand of lead storage battery (Acid, Gel, Dryfit, Heavy Duty, Solar, Fleece, AGM etc.)
The unit protects the battery from dangerous total discharge.
It protects the consumers and the equipment from low voltage as well as overvoltage in case of failures.
Automatic restart after battery recovery (charging).
High switching current 40 A, short-time overload of 60 A is admissible.
It can also be used as battery main switch by means of a simple ON / OFF switch (remote control, e. g. from the
living area).
EMERGENCY-ON function for low battery voltage.
Display of the switching state being visible from outside.
Compensation of the voltage loss in the battery cable by separate sensor cable.
The electronic delay avoids premature reaction, such as in case of voltage drop or if powerful consumers have
been connected.
Suitable for continuous operation (extremely low own consumption 0.002 A (in conformity with EN13796).
No own electricity consumption in case of disconnection by means of external switch (remote control).
Installation:
1.
Chose an installation place being clean and being protected from humidity and dust.
2.
The installation place of the unit should be chosen in such way, that the cables of battery and consumers can be as
short as possible (losses). Ensure, that the control lever „EMERGENCY“ can always be operated and that it is not
blocked by soiling, objects, transported goods etc.
3.
The unit is fastened solidly with screws in the casing flanges. The unit can be installed in any position. However,
ensure that the terminals and operating elements are easily accessible.
4.
Observe to fasten the connection cables in such a way, that neither tensible force, nor force of pressure or bending
load are existing.
Connection
(Please Observe Connection Plan 1 or 2):
ALWAYS DISCONNECT THE POWER SUPPLY TO THE BATTERY PRIOR TO WORKING ON THE
ELECTRIC SYSTEM TO AVOID SHORT-CIRCUITS!
It is recommendable to use connection cables of different colours to avoid defects and malfunctions due to mixed up
connections.
Basically: Only use red cables for Plus connection "+" and black cables for minus connection "-".
Eventual wrong polarization will result in failure of the unit, but it will not be damaged.
If the connection cables for battery and „Load“ are mixed up, the unit will continue working, but the low-voltage
disconnection will not be functioning. The battery continues supplying the consumers.
Observe the cable cross-sections and the polarity. Insert the fuses near the battery (protection against cable fire).
