SECTION 1 Important Safety
Warnings
Read this Section First
The AX500 is a power electronics device. Serious damage, including fire, may
occur to the unit, motors, wiring and batteries as a result of its misuse. Please
review the User’s Manual for added precautions prior to applying full battery
or full load power.
This product is intended for use with rechargeable batteries
Unless special precautions are taken, damage to the controller and/or power supply
may occur if operated with a power supply alone. See“Power Regeneration Consid-
erations” on page 31 of the Users Manual. Always keep the controller connected
to the Battery.
Avoid Shorts when Mounting Board against Chassis
Use precautions to avoid short circuits when mounting the board against a metallic
chassis with the heat sink on or removed. See “Attaching the Controller Directly to a
Chassis” on page 151.
Do not Connect to a RC Radio with a Battery Attached
Without proper protection, a battery attached to an RC Radio may inject its voltage
directly inside the controller’s sensitive electronics. See
Beware of Motor Runaway in Improperly Closed Loop
Wiring or polarity errors between the feedback device and motor in position or
closed loop position mode may cause the controller to runaway with no possibility
to stop it until power is turned off.
