2.0 Installation

Before installing the ME-SBC

TM

, read this entire section to be aware of all as-

pects 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 quali

fi

 ed personnel, such 

as a licensed or certi

fi

 ed electrician. It is the installer’s responsibility 

to determine which safety codes apply and to ensure that all ap-

plicable 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

TM

; using the supplied #8 x 3/4 screws (x4).  Allow ample room to 

access the three adjustment dials, to view the LEDs and to access the terminal 

blocks; refer to Figure 2-1 for dimensions on the ME-SBC

TM

.

CAUTION: 

Do not mount the ME-SBC

TM

 in a closed battery compart-

ment or in an area 

where water 

or any other liquid can enter the 

ME-SBC

TM

 and cause shorting or corrosion.  The internal circuit board 

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.
