troubleshooting of components within the IQ 200 Modules. If an IQ 200 Module is
determined to be at fault, replace it with a spare and return the malfunctioning
Module to Cutler-Hammer for repair.

The IQ 200 is designed to be a self-contained and maintenance-free unit. The
printed circuit boards are calibrated and conformally coated at the factory. They are
intended to be serviced by factory trained personnel only.

-20° C to 50° C and the display unit within a range of 0 ° C to 50° C. The environ ment
