• The main electrical supply cable and the terminals, including the user terminal cable, are correctly
connected.
• All cables are secured to the system.
Check Wiring and Components
For wiring and components, perform a preliminary check to verify the system is functional:
• Check that the system has been installed correctly.
• Check that the wiring cable sections meet current capacity. Report any incorrect mounting and
setting to the AAST who installed the system so that the necessary modifications can be made.
• Check that the grounding cables have been installed in the controller box and unit as shown in
the graphic.
Perform the Step-Test
The purpose of this test is to simulate real operation without damaging components due to incorrect
operation or protection failures.
Use the step test to check that the relays, breakers, and components work normally. For details, see
“Execute the Step-Test” on Page 63.
