WARNING:
IT IS THE RESPONSIBILITY OF THE INSTALLER TO ULTIMATELY CONFIRM THE
CONFIGURATION USED FOR ANY PARTICULAR INSTALLATION IS SAFE FOR ITS
INTENDED USE. AEM HOLDS NO RESPONSIBILITY FOR ANY DAMAGE THAT
RESULTS FROM THE MISUSEOF THIS PRODUCT.
Working on Electric Vehicle tractive systems with high voltage battery packs requires special experience
and training. Doing this safely is entirely the responsibility of the installer. AEM has done everything it can
to ensure the VCU has appropriate fault detection and failsafe logic but that does not mean that your
installation will be safe or that your VCU installation will not interfere with other systems on your vehicle and
create a hazardous situation. It is the responsibility of the installer to understand the implications of each
stage of tractive system installation and testing, and to know what might be unique about your application
that presents an unintended hazard or potential safety issue –
and to solve it.
Following is a brief list of recommended practices. This is not a comprehensive list; as noted below, if you
are not well-versed in the appropriate installation and testing procedures, you should refer the installation
and calibration to a reputable installation facility or contact AEM EV for a referral in your area.
When access is required near the battery pack, the cell segments must be separated by using an
appropriate maintenance disconnect plug.
When working on the battery pack or tractive system, safety glasses with side shields and
appropriate insulated tools must be used.
Always wear Class 0 gloves rated at 1000V with leather protectors.
Only use a CAT III rated digital multi-meter (DMM) and test leads.
When working on the battery pack or tractive system, use the one hand rule: work with one hand
keeping the other behind your back whenever possible.
During initial system power up and testing, the vehicle must be raised off the ground and supported
appropriately. Wheels/tires should be removed.
During the VCU firmware upgrade process, battery cell segments must be separated by using an
appropriate maintenance disconnect plug.
Do not make calibration changes while the inverter PWM is enabled.
USE THIS PDU WITH EXTREME CAUTION. MISUSE AND/OR IMPROPER INSTALLATION CAN CAUSE
SIGNIFICANT DAMAGE TO YOUR VEHICLE AND PROPERTY BELONGING TO YOU OR OTHERS, AS
WELL AS PERSONAL INJURY OR DEATH. IF YOU ARE NOT WELL VERSED IN THE INSTALLATION
OF TRACTIVE SYSTEMS OR CONFIGURING THE CALIBRATIONS IN THE AEM EV VCU THAT ARE
NECESSARY TO CONTROL THE VEHICLE, YOU SHOULD REFER THE INSTALLATION AND VCU
CALIBRATION TO A REPUTABLE INSTALLATION FACILITY, OR CONTACT AEM EV FOR A
REFERRAL IN YOUR AREA. IT IS THE RESPONSIBILITY OF THE INSTALLER TO ULTIMATELY
CONFIRM THAT THE INSTALLATION AND CALIBRATIONS ARE SAFE FOR ITS INTENDED USE.
