Wiring
Connect the Model 3300 or Model 3500 to a power supply using the following steps:
1. Connect 18 to 14 AWG (0,75 to 2,5 mm
2
) wiring to the power supply wiring connector.
See Figure 1-1.
2. Ground the transmitter as follows:
a. Connect the ground wire to the green power supply ground screw. See Figure 3-1.
b. Connect the power supply ground wire directly to earth ground.
c. Keep all ground leads as short as possible.
d. Ensure that all ground wiring has less than 1 ohm impedance.
3. Plug the power supply wiring connector into the power supply wiring terminals. See
Figure 3-18.
4. Slide the retaining clip over the wiring, then tighten the screw to hold the clip in place.
See Figure 1-1.
5. (Optional). Install a user-supplied switch in the power supply line.
In Europe, install the switch close to the Model 3300 or Model 3500 in order to comply
with low-voltage directive 2006/95/EC. For details, see standard EN 61010-1:2010
clause 5.4.3.d.
