Battery Master Isolation Switch BMIS-4PN, BMIS-4PP
THE BATTERY MASTER ISOLATION SWITCH (BMIS) The Battery Master Isolation Switch (BMIS) allows for manual isolation of a vehicle’s (trucks) electrical system from its battery. The BMIS will also ensure that no loads are drawn from the vehicle whilst not in use, thereby reducing flat battery faults. The BMIS models are intended to meet the compliance and specification requirements found in this document and are designed for use with roll over switches or sensors (ROS).
WARNINGS & SAFETY INSTRUCTIONS 1. 2. 3. 4. 5. Ensure that a correct grounding point is used. Bad grounding of the unit will result in poor or no operation. Do NOT use the BMIS to shut off the engine except in an emergency or for routine testing. Use the ignition key as per normal vehicle operation. It is recommended for an engine shutdown test, to perform this on a fully charged battery, or allow a few minutes of engine operation beforehand to recharge the battery as much as possible.

1 INSTALLATION 1.1 Mounting the BMIS STEP 1. Bolt the BMIS to a mounting plate with 4 x M8 anti-vibration fasteners and large flat washers as shown (Grade 8.8 minimum). Recommended to use 19mm OD, 1.6mm Flat washer as a minimum size. TORQUE: 10Nm then 20Nm in a cross pattern (to avoid stressing the housing) ENSURE THAT SWITCH IS OFF BEFORE INSTALLING THE BMIS UNIT (MARKED ‘0’). ENSURE THAT THE BMIS IS MOUNTED IN THE ORIENTATION AS DEPICTED ON A FLAT PLANE OR USING THE BMIS-AP.
1 INSTALLATION STEP 2. Wire the power and ground connections in the order shown below. TORQUE: 20Nm 2 4 1 3 Alternator B+ Connection ENSURE THAT ALL WIRES ARE TERMINATED CORRECTLY. ENSURE THE SWITCH IS IN THE OFF POSITION (MARKED ‘0’) BEFORE COMMENCING THIS STEP. THE ALTERNATOR B+ CONNECTION IS TO BE CONNECTED TO THE VEHICLE POSITIVE (TERMINAL 3 ). NO ADDITIONAL WASHERS TO BE USED ON THE TERMINALS. ENSURE CABLES ARE ALIGNED PROPERLY SO THEY DO NOT INTERFERE WITH RED COVER.
1 INSTALLATION STEP 3. Insert and secure the Data connector, ensuring that pins align correctly before insertion by aligning the guides on the plug housing. The wiring diagram for the data connector is on page 10. A SEALING PLUG SHOULD BE USED IF DATA CONNECTOR IS NOT USED. IF ALTERNATOR FIELD WINDING NOT CONNECTED, ACTIVATING THE SWITCH MAY NOT STOP THE ENGINE. ENSURE THE SWITCH IS IN THE OFF POSITION (MARKED ‘0’) BEFORE COMMENCING THIS STEP.
1 INSTALLATION STEP 4. Place cover on unit and secure with 3 x phillips head screws. TORQUE: 2Nm THE RED COVER MUST BE INSTALLED TO PROTECT AGAINST ACCIDENTAL SWITCH ACTIVATION. CONFIRM OPERATION POST INSTALLATION.
1 INSTALLATION STEP 5. Install Remote Switch and Roll Over Sensor / Roll Over Switch (ROS) if required. Refer to component supplier instructions. STEP 6. Test the unit by switching to ‘on’ position (marked ‘1’) and checking that the indicator led is lit. The unit should stay in the on position. • If installed, push the remote switch. This should cause the switch to turn off (marked ‘0’). The LED will also turn off. Ensure field winding is isolated.

2 USER GUIDE 2.2 LED Indication • The LED is ON when the truck power is Connected. • The LED is OFF when the truck power is Disconnected. • The LED is flashing when the BMIS is in fault or in self test mode. 2.3.1 LED Fault & Self-test Conditions Faults are indicated by flashing of the Warning Lamp and the LED on the unit. If the LED is on solid, the unit is working correctly.
3 TROUBLESHOOTING 3.1 Remote Switch If the remote switch does not work, check that all four wires are connected to the contacts (DPST type) as per the data connector wiring diagram (figure 1.3). The remote switch will not work if only two wires are connected to a single contact. Do not short wires together when connected to the remote switch, this will render the remote switch inoperable with the Redarc BMIS.
3 TROUBLESHOOTING 3.3 Battery not charging Check alternator field connections. • Bridge the field isolation connection at the alternator to verify correct operation. • Bridge the BMIS harness 4 FAQS Question: Is the unit protected against voltage spikes? Answer: Yes, the BMIS incorporates a number of spike protection components specifically designed to reduce the risk of damaging the unit.
6 MAINTENANCE & CLEANING If the BMIS is installed or used in dirty conditions, check and clean on a regular basis. Do not open the Unit by removing the rear cover. Clean the unit with warm, soapy water. • Do Not high pressure clean. • Periodically check that the screws and nuts are tight and for correct torque on power on battery and starter motor connections. • Periodically check isolation switch function in accordance with warnings found on page 1 of this manual.
7 STANDARDS & TESTING 7.1 Standards and Testing The BMIS 4-PP and 4-PN are Tested/Certified to: Reference Title IEC 60529 IP66/67 Degree of protection provided by enclosures UL94 Tests for flammability of plastic materials for parts in devices and appliances AS/NZS CISPR 11 GROUP 1 CLASS A Industrial, scientific and medical (ISM) RF equipment electromagnetic disturbance characteristics.
