Removing Motor Protection Switch
To remove the motor protection switch proceed as follows:
1. Using a Torx screwdriver No. 20, remove the front panel of the power distribution.
2. Pull the blue-green shorting plug forward. 
If necessary you may use a screwdriver (No. 0) suited to the relatively high amounts of
force that are needed.
WARNING!
Always make sure that the power supply is disconnected before commencing any service 
work on the transmitter rack. This will prevent injury due to electric shock and avoid dam-
age to the instruments.
