Section 3. Operation
Switches are provided to disconnect each phase from the mains
(Figure 9). All three switches must be in the off (“O”) position before
performing dielectric testing of a system where the PT module is
connected. When the test is complete, all switches must be in the on
(“I”) position for the module to function as intended.
• CAUTION
DIELECTRIC TESTING OF A SYSTEM CONTAINING A PT MODULE WITH THE
PHASE CONNECTED WILL DAMAGE THE PT MODULE. DISCONNECT ALL
OF THE PHASES FROM THE MAINS (BY SELECTING “0”) BEFORE TESTING.
AFTER TESTING, RETURN ALL PHASE SWITCHES TO THE “I” POSITION.
