To make the signal, relay contact, and power connections:
1. General Purpose (GP) Analyzers:
Open the Electronics Enclosure and open all of the fuses.
Purged Analyzers (Hazardous Locations):
Open the Electronics Enclosure and open all of the fuses. Open the
explosion-proof power-disconnect switch.
Loosen and remove all but one of the (24) M10 screws from the
Disconnect Enclosure door. Keep this screw in place until you are
ready to terminate connections inside the Disconnect Enclosure.
2. Terminate the input signals, analog output signal(s), and alarm re-
lay contact conductors (see Figure 3-7 and related Final “As-Built”
drawings).
GP Analyzers:
Route the input signals, analog output signal, and alarm relay contact
conductors into the Electronics Enclosure and terminate the wires.
Purged Analyzers:
Route the input signals, analog output signal, and alarm relay contact
conductors to the Disconnect Enclosure.
Install cable glands on the signal/relay cables as per the manufac-
turer’s instructions. Connect the cable glands to the signal/relay cable
entries on the Disconnect Enclosure. In all cases, all unused cable
entry ports must be plugged with a certified Ex d plug.
Route the input/output signals and alarm relay conductors into the
Disconnect Enclosure.
Apply sealing compound in the signal/relay cable glands as per the
manufacturer’s instructions.
Terminate the signal/relay connections inside the Disconnect
Enclosure.
