If any equipment in your system has a grounded AC plug, then that ground pin must be connected to the receptacle ground. The shield is optional.

Also unless the shield is heavy wire braid, you can't use that as an AC power electrical ground. The ground wire must be the same equivalent gauge as the other two wires. On factory made shielded power cords, there are three insulated wires with the addition of a shield wire. Could braid or foil with a drain wire. The shield is usually tied to the ground wire at both ends. And this double ground wire does not create a ground loop in a six foot power cord.

Are you using cable listed by UL (in USA) or your country's electrical product safety organization? I hope so because using cable stock not rated for primary AC power is a fire and safety hazard.
