Chapter 3 Wiring and Installation 3.1 Mounting the Controller The controller can be oriented in any position which should be as clean and dry as possible, and if necessary, shielded with a cover to protect it from water and contaminants. To ensure full rated output power, the controller should be fastened to a clean, flat metal surface with four screws. - Page 8 Figure 1: SPM-X mounting holes’ dimensions (dimensions in millimeters) Height: 41 millimeters Figure 1:SPMXX151E mounting holes’ dimensions (dimensions in millimeters)

Page 16: Chapter 4 Maintenance
Chapter 4 Maintenance There are no user-serviceable parts inside the controllers. Do not attempt to open the controller as this will void your warranty. However, periodic, exterior cleaning of the controller should be carried out. The controller is a high powered device. When working with any battery powered vehicle, proper safety precautions should be taken that include, but are not limited to, proper training, wearing eye protection, avoidance of loose clothing, hair and jewelry. - Page 17 Table 1: LED CODES Green LED Code LED Code Explanation Solution Green Off No power or 1.
