Owner`s manual

How hot to run the BMS regulators during the final absorption phase of charging is a

function of the ambient temperature and how fast the vehicle needs to get back into

service. Higher heat sink temperatures will make the absorption phase take less

time but is more risky to the regulators. When the upper thermal threshold on a

regulator has been reached, the reg will pull the hot reg line to +5 volts. This will tell

the charger to stop charging until the temperature of the heat sink drops below the

thermal limit. Adding airflow across the regulators will dramatically help cooling the

regs and speed up charge equalization by allowing more dissipation.

NOTICE! Manzanita Micro strongly advises air cooling of the BMS regulators for

maximum dissipation capability and longevity of the reg. For more information on

regulator cooling see the appropriate Manzanita Micro regulator manual for your

BMS.

Reg Bus Cable Construction;

The 6-wire RJ cable which is used to connect the regulators is a common data

transfer cable and is available at most any electronics store. The 6-pin connector

plugs are usually clear and it is easy to crimp them using an appropriate crimping

tool with a 6-pin die. These are also readily available.

NOTICE! RJ cable is quite rugged but take care not to cut or sharply bend (and/or

fatigue) the cable in order to avoid errors from broken internal wires. Additionally,

follow the proper cable construction techniques listed below and make sure that all

the wires are installed in the correct orientation. (See figure 11.)

Proper Reg bus cable construction is not difficult but it requires keen attention to

detail on the part of the person installing the plug ends onto the RJ cable. The

following steps tell how to correctly make a reg bus cable suitable for use with any 6-

Pin Manzanita Micro product.

Step 1: Cut the RJ cable to the desired length. It is advisable to err on the long

side because each of the cable’s ends will be pushed to the back of their respective

RJ receptacles.

Step 2: Strip about a quarter inch of the thick “flat” outer jacket off of each end

of the cable in order to expose the 6 colored wires inside. Most RJ crimping tools will

have a special wire stripping section with a guide which will allow you to quickly strip

the correct length of cable jacket off.

Step 3: Hold the flat RJ cable in front of you in your left hand with one end

pointing towards you and one away from you.

Step 4: Looking down at the cable in your hand make sure that the end facing

away from your body has the blue wire to the right side.

Step 5: Now take an un-crimped plug-end in your right hand and with the tang

oriented on the bottom side, slide the outward facing end of the flat RJ cable into the

slot in the un-crimped plug. Make sure it is not crooked and push it all the way into

the un-crimped plug. (see figure 11.)
