Insulation test
Preliminary operation
• Insulation test have to be performed after complete and correct functional test of the lift have been
made.
• Position the car between two floors and check that all doors are closed.
• Check that AM circuit breaker (on control panel) is closed.
• Switch off the mains (both power and light supply).
• Remove all yellow/green wires from earth bar, except those connected to metal parts and to earth
disperser.
• Disconnect yellow/green wire from terminal 100, in controller and in car connection box.
• Disconnect yellow/green wire from terminal 100 in the emergency battery drive SEC-3EBD
• Remove connector P8 on SEC-3Q board.
• Remove connector CAL on SEC-3FDR board.
• Remove all connections from inverter (if provided).
• Remove all connections between controllers (if multiplex lift group) and perform complete test
procedure on every single lift.
Insulation measures
By a 500V insulation tester, check resistance values between terminals according following table.
Measured values (in megaOhm) must be higher than 0.5 MΩ.
