Sensor Connector J1 Wiring
A.2 Sensor/Analog Outputs Connector J1 Wiring
Warning
The sensor connector is for use with an AMI LHe sensor and the
wiring for the sensor is to have no live parts which are accessible.
Conductors connected to its terminals must be insulated from user
contact, and from other conductors which the user may contact such
as the analog output conductors, by basic insulation rated for 100
VAC (Category I).
