Procedure
• The shielded interconnecting cable between the field unit and controller is already in place
with wires clearly identified at both ends
• An AC power source of adequate current rating is available at both locations.
1. Unscrew and remove the lid from 5000 Field Unit.
2. Connect controller signal and alarm outputs to user recording equipment as shown i
in the CD package.
3. Connect AC power source to:
Field Unit — TB1-1 AC line, TB1-2 AC Neutral, and GND to TB1-3 or to chassis ground stud.
Controller—TB5-1 AC line, TB5-2 AC NEUT, and GND lug. TB5-3 can be used to jumper line voltage
to Sample and Alarm Common.
4. Instrument grounding is mandatory. Performance specifications and safety features are void
ated from an improperly grounded source. Check ground integrity to all portions of the
if unit is oper
analyzer before power up. See Fig. 5e for proper internal grounding instructions.
