Figure 5 Junction Box
The following number refers to Figure 5 above:
1 = Junction Box (Vaisala Termbox)
The distance between the equipment and the Mains Distribution
Transformer, and the power consumption of the equipment, dictate the
thickness of the cable. The minimum requirement for the power cable is
3 x min 1.5 mm
2
(AWG 15) 3-conductor power cable.
Recommended AC (mains) wire cross sections and typical cable
diameters for AC (mains) voltage 230 VAC are shown in Table 6 on
page 32. It applies to copper cable and a 5% voltage drop. For the voltage
115 VAC the maximum distances should be divided by four. The
maximum power consumption of FS11P is 400 W.
