WhisperPower WBI 150-2 Low Voltage Drop Battery Isolator Instruction Manual

WhisperPower WBI 150-2 Low Voltage Drop Battery Isolator

Product Information

The WhisperPower Battery Isolator WBI 150-2 IG | WBI 150-3 IG is a low voltage drop battery isolator suitable for 12 and 24 VDC systems. It is designed to start modern electronic regulated alternators charging the batteries by measuring a certain voltage at the B+ terminal. The IG-connection can be connected to the battery voltage coming from the ignition key switch. It is voltage drop free and has unique features which make it different from other battery isolators. The product dimensions are 146 x 99 x 85 mm (WBI 150-2 IG) and 146 x 85 x 152 mm (WBI 150-3 IG), and it weighs 685 g and 810 g, respectively.

Product Usage Instructions

1. Install the Battery Isolator according to the instructions provided in the manual.
2. Never use the Battery Isolator at a location where there is danger of gas or dust explosions.
3. Connections and safety features must be executed according to the locally applicable regulations.
4. Use cables with appropriate size wire and keep the cable connections as short as possible. Use reliable terminals and fasten the bolts tightly, but do not over torque.
5. The IG-connection can be used to start modern electronic regulated alternators charging the batteries by measuring a certain voltage at the B+ terminal.
6. In this case, connect the IG-connection to the battery voltage coming from the ignition key switch.

Product description

The Battery Isolator is an electronic device which is designed to distribute the charge current with a low volt-age drop between several (sets of) batteries with the same nominal voltage. The Battery Isolator prevents the current from flowing from one battery to another. The Battery Isolator can only be installed in the positive lead between the supplying source (for instance a charger or an alternator) and the batteries. Therefore the negative output of the supplying source should be connected directly to the negative connections of the battery sets. The Battery Isolator has no voltage drop when the batteries are fully charged. This is achieved by using the lat-est electronic technologies, other diode splitters have at least a voltage drop of 0,7 Volt and at a high charging current this voltage drop can reach 1,5 Volt. The voltage drop of the Battery Isolator will never exceed 0,4 Volt at max amperage. At a charging current of 20 Amps. per battery, the voltage drop is negligible. The Battery Isolator has therefore no influence on the charging characteristics of the charger or the alternator. Diode com-pensation is not required to be able to charge the batteries up to 100%

IG connection

The IG-connection can be used to start modern electronic regulated alternators charging the batteries. These alternators have to measure a certain voltage at the B+ terminal. In this case the IG-connection has to be con-nected to the batteryvoltage coming from the ignition key switch. This is another unique feature of the WBI 150-2 IG & WBI 150-3 IG.

Installation

• Be sure that the output of the supplying source is switched off during installation. Disconnect all electrical connections to the charger/ alternator and the batteries. Also be sure that no consumers are connected to the batteries during installation, to prevent hazardous situations. Install the Battery Isolator not only as close as possible to the supplying source, but to the batteries as well, but do not install The Battery Isolator straight above the batteries because of possible corrosive sulphur fumes. The Battery Isolator must be installed in a well-ventilated environment, as high currents will heat up the Battery Isolator. Preferably, the battery isolator should be mounted on a flat metal surface (never directly to the main engine), with the fins vertical.
• For correct connection see drawing. Connect the negative poles of the battery sets and the supplying source to a common ground. When DC-power is available from the Battery charger / Alternator, the green LED on top of the Battery Isolator illuminates
• The Battery Isolator automatically detects the nominal charge voltage (12V or 24V). Unlike conventional battery isolators, the Battery Isolator is almost free of voltage drops. Therefore, when the Battery Isolator is applied, the output voltage of the supplying source should NOT be increased for diode compensation. No internal or external settings are required.

Safety regulations and measures

1. Install the Battery Isolator according to the stated instructions.
2. . Never use the Battery Isolator at a location where there is danger of gas or dust explosions.
3. Connections and safety features must be executed according to the locally applicable regulations.
4. Use cables with appropriate size wire and keep the cable connections as short as possible. Use reliable terminals and fasten the bolts tightly, but do not over torque.

Liability

Manufacturer cannot be held liable for:

• Damage resulting from the use of the Battery Isolator.
• Possible errors in the included manual and the consequences of these.

Guarantee terms

The manufacturer guarantees that the Battery Isolator has been built according to the legally applicable standards and stipulations. During production and before delivery all Battery Isolators were exhaustively tested and controlled. If you fail to act in accordance with the regulations, instructions and stipulations of this user’s manual, damage can occur and/or the unit will not fulfil the specifications. This may mean that the guarantee will become null and void. The guarantee period is 2 years.
