CAUTION! To prevent damage from incorrect connec-
tions, do not turn on the heater power or oth-
er output power before testing the
connections as explained in Testing the Sys-
tem on page 26.
NOTE! Do not connect the controller’s dc common
(COM) to earth ground . Doing so will defeat
the noise protection circuitry, making mea-
surements less stable.
