Installation and Operating Manual 

 

Battery Protector 100 

Switching Capacity 12 V - 24 V / 100 Amperes

  

No.  3078 

 

 

Please read the Safety Regulations, mounting instructions and operating manual completely prior  

to starting connection and start-up. 

 

 

Fully automatic battery protection for intervention vehicles, high-quality campers and the marine field. 

The battery protector 100 is connected between supply battery and consumer loads. It protects the battery from dangerous 

deep discharge and the consumer loads from low voltage as well as from overvoltage. 
Note: The values being indicated in parentheses ( ) apply to 24 V operation. 

 

 

Functions: 

 

The unit protects the battery from dangerous deep discharge.

 

 

Maximum admissible current 100 A; thus, it is also suitable for high-capacity consumer loads.

 

 

Suitable for any type and brand of lead batteries (Acid, Gel, Dryfit, Heavy Duty, Solar, fleece, AGM etc.). The automatic 

switching threshold ensures an additional protection against latent consumer loads. 

 

Suitable for lithium batteries LiFePO4. 

 

Disconnection of the consumer loads for protection against dangerous overvoltage.

 

 

The disconnection can be cancelled manually by means of the 

"EMERGENCY-ON"

 function.

 

 

It can also be used as efficient, remote-controlled main-switch with battery control.

 

 

Full remote control with external single-pole remote switch is possible. 

 

Preliminary alarm as soon as the switch-off level is reached. 

 

Visual indication of the operating state. 

 

Audible indication in case of preliminary alarm and disconnection (can be deactivated, optionally). 

 

Output for external alarm indication (max. 0.2 A short circuit-proof). 

 

Input for separate sensor line for unfalsified measurement of the battery voltage. 

 

Immediate emergency shut-down in case of defective battery or extremely discharged battery. 

 

Least own electricity consumption during operation (acc. to EN13976).  

 

No own electricity consumption in case of disconnection by external remote switch. 

 

 

Installation: 

1.

 

Choose an installation place being clean and being protected from humidity and dust. 

2.

 

The installation place of the unit should be chosen in such a way, that the cables of battery and consumer loads can 

be as short as possible (losses) to ensure that the push-button "EMERGENCY" is easily accessible. 

3.

 

Fasten the unit securely with screws at the casing flanges. The unit can be installed in any position.   

4.

 

In case of great distance to the battery, we recommend to connect a separate sensor cable.  

5.

 

The cable lugs of the connection cables for battery and load should be connected solidly to the terminal lugs 

"Battery" and "Load" by means of the delivered screws M6. Recommended tightening torque approx. 

6-7 Nm

.

 

The enclosed insulation protection angle must be installed as short-circuit protection for this area. 

6.

 

Observe to fasten the connection cables in such a way, that neither high tensible force, nor high force of pressure is 

acting on the terminal lugs.
