LX CEDI Modules

3.4. Electrical Connections
All LX modules have two electrical junction boxes (one on each endplate) to allow
convenient connection of the module to the DC power supply that provides the driving
force for the electrodeionization process. Only one electrical connection is required per
module, and either junction box can be used. Power connections to the terminal strip
inside the module junction box (see Figure 3-5 and Appendix B3) should be made with
12 or 10 AWG (4.0 or 6.0 mm
2
) wire and conduit or cord connections should be supplied
via the 1/2” NPT hole on the bottom of the junction box.
The DC wire color conventions used on the LX modules are as follows:
· Red/White (+) to DC positive terminal of power controller
· Black/White (–) to DC negative terminal of power controller
· Green/Yellow to earth ground
Terminal strip screws should be tightened to 7.0 in-lb
f
(0.8 N-m). Wire stripping length is
7.0 mm (0.276”).

3.4.1. Electrical Precautions
· Disconnect power before opening any enclosure and follow
accepted Lockout/Tagout procedures when working on the
system.
· Do not run AC and DC wiring within the same conduit. This may
cause interference and lead to malfunctions.
