Installation

The AMP-1-N is mounted in a rugged 2" x 3" metal
housing with screw terminals for easy installation.
When installing the AMP-1-N the metal case housing
must be grounded.
All input and output connections should be run with
shielded cable. Connect cable shield to shield terminal of
AMP-1-N (TBI pin 1). The signal line from the NAMUR
pickup to the AMP-1-N must be less than 100 ft. in length,
shielded and separated from relays, solenoids or other
sources of electrical noise.
