Removing the electrical components
1 Disconnect all the cables connected to the electrical components.
2 Remove the screws that fix the electrical components.
N O T E
• The maximum
open angle of the PCBs fixing plate is approximately 120 degrees. If you try to open it more than
120 degrees, the PCB fixing plate might not open due to insufficient electrical wiring lenght.
• Do not touch the electrical components of the PCB. Do not bend or apply excessive force to the PCB. This may
cause faults in the PCB.
Removing the electrical components from the sub electrical box (RAS-(14-18)FSXN).
1 Disconnect all the cables connected to the electrical components.
2 Remove the screws that fix the electrical components.
N O T E
• Match the
numbered terminals with the band marked with numbers when reassembling them. If they are
connected incorrectly, this may cause a malfunction and damage the electrical components.
• Protect the electrical wiring so it does not get caught on the plate edge or the electrical components when
closing the PCB fixing plate when reassembling.
• The capacitor is charged with electricity when the power supply line is turned OFF. Do not touch the capacitor
terminals as this may cause electric shocks.
