3.7.2 Input Power
This unit operates at a MAXIMUM power consumption of 1.50A at
+28VDC with an operating voltage range of +18VDC (minimum) to
+32VDC (maximum). QUIESCENT operating power consumption,
by design, should not exceed 1.00A at +28VDC. Final power
consumption is at the discretion of the designer, but must not
exceed the stated MAXIMUM.
3.7.3 Grounding / Bonding
This unit provides for common circuit ground and chassis ground
connections. Both circuit and chassis grounds are referenced to
pin two (2) of connector J1. Circuit/chassis ground connection shall
be bonded to an electrically conductive chassis mounting point or
