17	Cylinder Plug	Cylinder plugs are press fit on cylinder electrode pins. These color
		coded connections should fit snuggly, on same color pins. Replace
		if loose or frayed.

18	Low Voltage Terminal Strip	The low voltage terminal strip is the location at which all controls are
		connected. See Installation for details.

		connected to the total controller, and monitor and activate all
		humidifier states.

20	Contactor	The contactor(s) when energized allow main power to energize the
		cylinder electrodes, allowing current to pass, boiling the water.

21	NORTEC OnLine Module	NORTEC ONLINE OPTION NHTC ONLY. This module allows the
	(Optional)	NHTC to be connected to the internet and communicate information
		to NORTEC via the internet. See NORTEC OnLine operation for
		details. NHTC only

22	Links Module	NORTEC LINKS OPTION NHTC ONLY This module allows the
	(Optional)	NHTC to communicate with a BMS system using the
		communication protocol requested at order. See NORTEC Links
		operation for details. NHTC only

23	Network Terminal Strip	The network terminal strip allows up to 13 NHTC units to be
		connected on one Links module and eight OnLine modules. See
		Installation of NORTEC Links and OnLine for details on wiring
		humidifier networks.

24	Fuse Holder	OPTIONAL FUSE PACKAGE provides protection of individual high
		voltage lines in the humidifier and does not replace fuse and
		external disconnect.
