Installation

2.0 Installation

Before installing the ME-SBCTM, read this entire section to be aware of all aspects of the installation; then you can thoroughly plan the details to ensure the overall system requirements are accomplished.

To assist you in planning and designing your installation; you should review the basic system diagram shown in Figure 2-2 and Figure 2-3.

Info: Installations should be performed by qualiﬁ ed personnel, such

as a licensed or certiﬁ ed electrician. It is the installer’s responsibility to determine which safety codes apply and to ensure that all applicable installation requirements are followed.

Info: Review the “Important Product Safety Information” on the

front inside cover page before any installation.

2.2 Location and Mounting

Select a location that is dry and away from extreme temperatures to mount

the ME-SBC

; using the supplied #8 x 3/4 screws (x4). access the three adjustment dials, to view the LEDs blocks

; refer to Figure 2-1 for dimensions on the ME-SBCTM.

CAUTION: Do not mount the ME-SBC

ment or in an area

ME-SBC

and cause shorting or corrosion. The internal circuit board

where water or any other liquid can enter the

in a closed battery compart-

Allow ample room to

and to access the terminal

is conformal coated to help prevent corrosion. However, a failure that is caused by corrosion is not covered by the warranty.

WARNING: This device is not tested for Ignition Protection. Do not

install this device in a gasoline engine room or any other area that requires an ignition protection rating.

2.4 Conﬁ gurations

The ME-SBCTM can be conﬁ gured to accomplish battery combining in a simple, ﬂ exible way. There are two methods and they are as follows:

25 Amp Combiner - This conﬁ guration is simple to install and use. The

3-wire connection system is similar to connection methods used by other battery combining products. One of the the advantages of this controller is the advanced combining options that are available to the installer. It is best to choose this method when designing systems where 25 amps or less are

required. For this conﬁ guration see Figure 2-5. Solenoid Drive - If more battery combining capacity (or Ampacity) is required

the installer can employ any solenoid, so long as the coil of that solenoid consumes less than 2 Amps. The source that provides power to the solenoid must not exceed 40 VDC. This circuit switches DC Negative to the accessory

terminal block position #4 entitled Solenoid (-). For this conﬁ guration please see Figure 2-6.

Installation

2.4.1 ME-SBCTM Wiring Connections - 25 Amp

CAUTION: Before connecting any wires, turn off any battery charger

and loads that are connected to the battery banks that the ME-SBCTM

will be combining.

Info: If installing in a boat, RV or truck, ensure the conductors

passing through walls, bulkheads or other structural members are protected to minimize insulation damage such as chaﬁ ng; which can be caused by vibration or constant rubbing.

The ME-SBC

should now be mounted if not please refer to section 2.2.

During installation please refer to Figures 2-5 during the following steps:

1. Unplug the Power Terminal Block from ME-SBC

and ensure the open-

ings are unscrewed enough to allow the wires to be inserted.

2. Select and connect an appropriately sized red wire

from terminal #1

- MAIN POS (+) on the Power Terminal Block to the positive terminal of the Main Battery.

3. Select and Connect an appropriately sized red wire with a white stripe

from terminal #2 - AUX POS (+) on the Power Terminal Block to the positive

terminal of the Auxiliary Battery.

4. Select and connect an appropriately sized a black wire

from terminal #3

- COM NEG (-) on the Power Terminal Block to the Negative bus-bar or

vehicle chassis.

Info: The Negative busbar must connect the negative terminals on the Main and Auxiliary Batteries together.

5. When all the connections are made and checked, plug the Power Terminal

Block into the ME-SBC

to supply DC power.

Info: If there is a miswire in the system the “Reverse Polarity” LED

will be on. Correct the polarity of the wires connected to the Main Terminal.

6. Immediately after applying DC power, the LED’s on the ME-SBC

should

come on as the unit goes through a power-up self-test. After the initial self-

test completes, the Status LED should be illuminated. If so, your ME-SBC

is now ready for set-up; if not, please refer to the troubleshooting section.

2.4.3 ME-SBCTM Wiring - Remote Volt Sense

The Remote Volt Sense Wire, or the wire connected to #6 - SENSE (+), can

be used to better sense when the batteries are being charged. As the ME-SBCTM

combines the Main and Auxiliary Batteries, the current path distributes

voltage drops throughout the circuit that may cause the ME-SBC

unneccessarily. The Remote Volt Sense Wire, if utilitzed, tells the ME-SBC

what the actual voltage is by bypassing the current path and therefore the

voltage drops. The Remote Volt Sense Wire can be connected at the battery

or at the charging source (i.e. Alternator, Solar, Wind, etc).

CAUTION: Before connecting any wires, turn off any connected

battery charger and ensure all negative

and positive battery cables

are disconnected from the battery bank.

Info: If installing in a boat, RV or truck, ensure the conductors

passing through walls, bulkheads or other structural members are protected to minimize insulation damage such as chaﬁ ng; which can be caused by vibration or constant rubbing.

to cycle

1. Install and connect the ME-SBC

as indicated in Section 2.2.2 or Sec-

tion 2.2.3

2. Remote Volt Sense Wire: Install a minimum of an 18 AWG wire between the Main Battery positive and the #6 - SENSE (+) on the accesories ter-

minal on the ME-SBC

. The Remote Volt Sense Wire should be fused at

0.25 Amps with a fast blow fuse.

Info: Connect the highest current cable directly to the battery ter-

minal, and in descending order in terms of ampacity, connect the

rest of the cables. The Remote Volt Sense Wire should be the last

connection on the battery. For a detail of this information, please see

the Main Battery positive post in Figure 2-7.

Figure 3-1, Battery combining setpoints

The above diagram represents a typical three-stage charging proﬁ le. The ﬁ rst of the three stages is Bulk Charge. This is where up to 80% of the charging is accomplished. During this stage the battery voltage increases signiﬁ cantly

and the current that the charging source is providing to the Main Battery

is at a maximum. The second stage is Absorption, during this stage the battery voltage is held at the Absorption voltage for a period of time. By the end of this process the charge on the battery bank is about 95% complete. The third and ﬁ nal stage is Float. In this stage, the remainder of the charging

is accomplished. As long as the Main Battery voltage is between the Low Voltage Disconnect and the High Voltage Disconnect, and the Main bat-

tery voltage is above the Connect Voltage, the ME-SBC

will pass charging

current through to the Auxiliary Battery.

4.0 Limitations of Throughput

The ME-SBC

can allow charge currents from either battery to ﬂ ow through

to the other battery (i.e. Main Battery to Auxiliary Battery or Auxiliary Battery to the Main Battery). When the MOSFET turns on inside the ME-

and the batteries are combined and a signiﬁ cant inrush of current

SBC occurs. This inrush may cause the ME-SBCTM to shutdown to protect itself or reduce how much current it actually lets through to the other battery. If the

ME-SBC tempt to recombine. If the ME-SBC

shutsdown to protect itself, it will restart in 10 Seconds and at-

reduces the output in order to maintain

a stable output, it will return to full output as soon as the average amperage

through the MOSFET lowers to a safe sustainable level.

note 1: When the ME-SBC about 1/2 of the available amperage. It will continue to operate like this until the total available Amps safely drops to a level the ME-SBC

is in the reduced output mode it only lets through

tinuously. With a current probe, it may look like 50% of the rated output.
