3.7.3 Using the Remote Outputs
The relay contact outputs are accessible on the 15 pin remote output connector. These contacts
provide status indication for IG1 and IG2 ON or OFF, degas ON or OFF, and fault detection. Figure
3-11 shows the pin designations. See Section 7.3 on page 7-4 for a description of fault relay
indications.
3.8 Connecting the RS-232 Computer Interface
Instructions for setting up this interface are in Section 2.1.4 on page 2-8.
This factory or field installed capability produces the signals shown in Table 3-4.
A mating DB-25S connector is supplied in the hardware kit. Use shielded cable to minimize
electromagnetic radiation or susceptibility. Ground the shield to the metal connector shell or to
Pin 1. Do not connect the shield to Pin 7.
