Installing the Transmitter

2.7Supplying power

In all installations, power must be provided to the transmitter. Refer to Section 2.3.3 for information on the transmitter’s power supply requirements.

A user-supplied switch may be installed in the power supply line. For compliance with low-voltage directive 2006/95/EC (European installations), a switch in close proximity to the transmitter is required.

Connect the power supply to terminals 9 and 10, under the Warning flap. Terminate the positive (line) wire on terminal 10 and the return (neutral) wire on terminal 9. Ground the power supply using the equipment ground, also under the Warning flap. See Figure 2-9.
