For continued protection against risk of fire, replace only with a fuse of the
same type and having the same electrical rating.
To determine whether you have a 120 volt or 240 volt early style Theta Controller,
look at the serial number on the Theta Controller. If it begins with an “E”, then it
is a 240 volt unit; if it does not begin with an “E”, then it is a 120 volt unit.
Note: Changing the fuse rating to the higher or lower specification does not allow
you to use the Theta Controller with an eddy current brake that was wired for
120 volt or 240 volt originally. Refer to “Verifying the Eddy Current Brake Wiring
Configuration” on page 1-26.
Note: If the eddy current brake has been rewired to a different voltage, you will
need a different Theta Controller. The original Theta Controller will not work.
