Battery Connections

Use a properly-sized ring terminal to connect the battery leads.

Danger

Electrical charge may still be present on the battery connections even after the battery has been disconnected or power switched off. This stored charge will dissipate in a few minutes, but take care not to short the + terminal to a ground point because an electrical arc and possible damage to the controller may result.

Warning

Do not overtighten the terminal connections. Use a maximum torque of 20 inch-pounds. Overtightening may cause damage to the controller.

Motor Terminals

The P250 motor connections are made using the supplied M6, Torx T30 screws. A ring terminal such as TE Connectivity part number 321598 can be used to terminate the leads. Connections should be torqued to 40-45 inch-lbs.

Note

For a Brushed motor with only two motor connections, use the 'W' and 'U' connections

Warning

Do not overtighten the terminal connections. Torque to 20 inch-pounds. Overtightening may cause damage to the controller.
