This equipment is designed for installation in an enclosure
which provides adequate protection against electric shock. The
enclosure must be connected to earth ground.
Local requirements regarding electrical installation should be rigidly
observed. Consideration should be given to prevent from unauthorized
person access to the power terminals.
Proper sensor installation can eliminate many problems in a control
system. The probe should be placed so that it can detect any
temperature change with minimal thermal lag. In a process that requires
fairly constant heat output, the probe should be placed closed to the
heater. In a process where the heat demand is variable, the probe should
be closed to the work area. Some experiments with probe location are
often required to find this optimum position.
