Installing the Transmitter
2.7 Supplying 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.
