3.5. Initial power-up
•
Ensure that the equipment is correctly earthed
[
earth bolt (

) located at the bottom of the housing inside
the unit
]
.
•
Check the state of the fuses.
•
Proceed to the other electrical connections depending on the specifications of the installation.
•
Arm the overload protection of the variable speed controller circuit breaker (
2:4
).
•
Arm the overload protection of the main magneto-thermal circuit breaker (
2:1
), located behind the master
lateral door (
10:1
).
•
Upon power-up, the initialization sequence provokes the electrical opening of the obstacles, that close
immediately after. If the slave motor rotates in the wrong direction, switch off the main magneto-thermal
circuit breaker (
2:1
), and reverse the connection of the two phases of the slave motor. Rearm the overload
protection of the magneto-thermal circuit breaker (
2:1
) at the end of the procedure.
•
Press RESET on the Programmable Logic Controller (PLC), which reactivates the initialization sequence.
