Mounting
Analog Expansion Modules are contained in an encapsulated plastic case and may be mounted in any
convenient position. The construction of a Analog Expansion Module is durable enough to mount directly
on a genset using UNF ¼-20 or equivalent hardware. Hardware selection should be based on any
expected shipping/transportation and operating conditions. The torque applied to the mounting hardware
should not exceed 65 in-lb (7.34 N•m).
See Figure 10-1 for AEM-2020 overall dimensions. All dimensions are shown in inches with millimeters in
parenthesis.

Connections
Analog Expansion Module connections are dependent on the application. Incorrect wiring may result in
damage to the module.
NOTE
Operating power from the battery must be of the correct polarity. Although
reverse polarity will not cause damage, the AEM-2020 will not operate.
Be sure that the AEM-2020 is hard-wired to earth ground with no smaller than 12
AWG copper wire attached to the chassis ground terminal on the module.
Terminations
The terminal interface consists of both plug-in connectors and a permanently mounted connector with
screw-down compression terminals.
AEM-2020 connections are made with one 5-position connector, two 12-position connectors, two 16-
position connectors, and two 2-position thermocouple connectors. The 16, 5, and 2-position connectors
plug into headers on the AEM-2020. The connectors and headers have dovetailed edges that ensure
proper connector orientation. The connectors and headers are uniquely keyed to ensure that the
connectors mate only with the correct headers. The 12-position connector is not a plug-in connector and
