NOTES:

1.Equipment must be installed according to the applicable country wiring codes.

2.Surge Ground must be disconnected from the Chassis Ground during HIPOT (dielectric strength) testing.

3.All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases where users require the inputs to be isolated from ground, remove the ground braid between Surge and Chassis Ground. All line-to-ground transient protection circuitry will be disabled.
