3.1 PREPARING CONDUIT OPENINGS
The analyzer enclosure has five conduit openings. Two are
open and three are knockouts.
Conduit openings accept 1/2-inch conduit fittings or PG 13.5
cable glands. To keep the case watertight, block unused
openings with NEMA 4X or IP65 conduit plugs.
NOTE
Use watertight fittings and hubs that comply with the
requirements of UL514B. Connect the conduit hub to the
conduit before attaching the fitting to the analyzer
(UL508-26.16).
Figure 3-1 shows how to remove the knockouts. The knock-
out grooves are on the outside of the case. Place the screw-
driver blade on the inside of the case and align it approxi-
mately along the groove. Rap the screwdriver sharply with a
hammer until the groove cracks. Move the screwdriver to an uncracked portion of the groove and continue the
process until the knockout falls out. Use a small knife blade to remove the flash from the inside of the hole.
3.2 POWER, ALARM, OUTPUT, AND SENSOR CONNECTIONS
3.2.1 General Information
The analyzer is available in two mounting configurations.The positions of the power, alarm, output, and sensor ter-
minal blocks are different in each. See Figure 3-2 (panel mount) or Figure 3-3 (pipe/wall mount).
To reduce the likelihood of stress on wiring connections, keep the hinged front panel (-11 option only) attached to
the back cover while installing wiring. Be sure there is sufficient cable within the analyzer enclosure to avoid stress
on conductors and connections.
For ease of wiring, connections for power, outputs, and alarms are removable.
