) wire.
2. Using a flat-head screwdriver, loosen the captive screws that secure
the display cover to the housing.
3. Ground the transmitter as follows:
• Connect the ground wire to the green screw (power supply
ground; see Figure 11).
• Connect the power supply ground wire directly to earth ground.
• Keep all ground leads as short as possible.
• Ground wiring must have less than 1 ohm impedance.
4. Connect wires to terminals 9 and 10 on the gray terminal block (see
Figures 11 and 12).
5. Close the display cover and tighten the screws.
6. A user-supplied switch may be installed in the power supply line. For
compliance with low-voltage directive 73/23/EEC (European
