INSTALLATION:
Fasten arrestor in place. Use a Delta mounting bracket, part # MB, a pipe strap, or a knockout hole. Connect the black wires to the hot lines at any convenience point load-side of an existing fuse or circuit breaker. Connect the white wire to an existing ground system, the grounded metal frame work of the equipment to be protected, or make a ground source per NEC Article 250.
