CAUTION!
Without proper grounding, the CPC400 may not
operate properly or may be damaged.
CAUTION!
To prevent damage from incorrect connections,
do not turn on the ac power before testing the
connections as explained in Testing the System
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 measurements
less stable.
