DA-820 Series Hardware Installation ATTENTION 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 the ground, remove the ground braid between Surge and Chassis Ground.
DA-820 Series Hardware Installation HIPOT (Dielectric Strength) Testing Before performing the HIPOT test, you MUST remove the jumpers and disconnect the braided ground cable. Doing so can prevent the transient/surge suppression circuitry (which is connected to Surge Ground) from being activated during the HIPOT test. When finished, press the Power Switch button to start the system.
