Manual,

Prior to installation, inspect packaging and unit for any damage. Do not continue installation if unit has visible signs of damage.

Danfoss is not responsible for the design of the control input circuit outside of the installed Mil-Spec connector. Proper design

on the entire system as noted in the applicable standards is required for safe usage in hazardous environments.

The EDC is designed to be controlled from a DC current source or voltage source. Pulse width modulation (PWM) is not required. But, if

a PMW signal is used, use a carrier frequency between 200 Hz and 4000 Hz. Do not use a pulse current of more than 120% of that

required for full output(refer to unit speciﬁcations below).
