SECTION 1AX2500/2850

Quick Start

This section will give you the basic information needed to quickly install, setup and run your AX2500/2850 controller in a minimal configuration. The AX2850 is a version of the AX2550 controller with the addition of Optical Encoder inputs.

Important Safety Warnings

The AX2500/2850 is a high power electronics device. Serious damage, includ- ing 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 apply- ing 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 Regener- ation Considerations” on page 31 of the Users Manual.

What you will need

For a minimal installation, gather the following components

•One AX2500/2850 Controller and its provided cables

•12V to 40V high capacity, high current battery

•One or two brushed DC motors

•One R/C to DB15 connector (provided)

•Miscellaneous wires, connectors, fuses and switch
