Terminal Torque Requirements

Once the wires have been installed, torque the terminals as follows. Be careful not to overtighten.

•20 inch-pounds for #14-10 AWG wire

•25 inch-pounds for #8 AWG wire

•35 inch-pounds for #6 AWG wire

Wire Size and Over-current Protection Requirements

The wiring, over-current protection devices (fuses and circuit breakers), and installation methods used must conform to all national and local electrical code requirements.

Wiring should be protected from physical damage with conduit or a strain relief clamp. You should pull the temperature sensor cable through the conduit first as the connector may not fit if other wires have been pulled first.

Current Rating

Each model of the C-Series controller is rated for a maximum continuous current of 35, 40 or 60 amps. Since PV outputs can vary due to the array size or sunlight striking it, the safe minimum wire size should be based on the maximum current ratings.
