Installation and Operation Manual
POWER CONNECTIONS
The collector base unit requires a 100 - 240 VAC, 150-watt power source. The collector power source must be supplied by a
reliable source with an appropriate disconnect switch that meets local and NEC requirements. A conduit entry is located on the
bottom of the collector enclosure and should be used for power wiring to the collector.
Note
: Use ABB LTGUS02G-C, 1/2" Liquid-
Tight conduit or equivalent.!!
Note:
conduit, power and ground wiring should only be installed by qualified personnel per
applicable OSHA, NEC, local codes and laws.
SOLAR INSTALLATIONS
Solar arrays should be installed to provide AC power. Power connections are the same as an AC installation.
See Appendix IV: Solar Installation.
AC INSTALLATIONS
Ensure AC power has been disconnected and all collector circuit breakers are in the off (down) position. Install the Line (L)
Neutral (N) and Ground (G) in the indicated terminal blocks using the method shown in the Connection Procedure section below.
CONNECTION PROCEDURE
If your AC input wire is a stranded wire you will need to prepare the wires for installation by crimping a ferrule on the end of each
of the three wires (line, neutral, and ground). The length of the ferrule shall be 12 mm and the barrel size shall be based on the
wire gauge. Refer to the manufacture terminal and crimper instructions for the procedure to crimp the ferrule.
Insert the wires by forcefully inserting a 1/8”-wide, slotted screw driver into the port located above the wire entry hole. This
action unlocks the wire port allowing insertion of the wire into its connection port (approx. 3/4” depth). Remove the screwdriver
to lock the wire into its terminal (Figure 10). Always test each wire connection by pulling on the selected wire (Figure 11).
