Section 3. TLX106 Instrumentation Installation
3-3
The solar panel should be oriented to receive maximum insolation over
the course of the year. Suggested tilt angles (referenced to the horizontal
plane) are listed below.
Site Latitude Tilt Angle
0 to 10 degrees 10 degrees
11 to 20 Latitude + 5 degrees
21 to 45 Latitude + 10 degrees
46 to 65 Latitude + 15 degrees
>65 80 degrees
b) After determining the tilt angle, loosen the two bolts that attach the
mounting bracket to the panel. Adjust the angle, then tighten the bolts.
Secure the lead wire to the mast using wire ties. Make electrical
connections as described in 3.1.1a above.
3.1.3 AC Power Installation
a) The AC power option includes a 120 VAC to 16 VAC. The transformer
should be mounted inside a user supplied junction box according to local
electrical codes. Dangerous electrical accidents may be avoided by
locating the transformer remotely and burying a low voltage line to the
station. The low voltage will carry up to 500 feet on an 18 AWG power
cable.
b) Shut off 110 VAC power at the main breaker. Connect the primary leads
of the transformer to 110 VAC following instructions provided with the
transformer. Connect a two conductor cable to the secondary terminals of
the transformer. Route the cable from the transformer to the TLX106
Enclosure according to local electrical codes.
3.1.4 Enclosure Installation
1. Mount and ground the TLX106 enclosure on the TLX106 Tower as
shown in Figure 3.1-3.
a) Place the enclosure low on the tower. Do not tighten clamps.
b) Install the sensor arm (TLX106) as described in Section 4.
