If the installation does not use the optional indoor power supply:
Use a power supply with appropriate voltage, current and
environmental ratings.
Use a power cable with appropriate environmental ratings, and with
conductors properly sized for the length of run, to ensure the voltage
at the sensor is not below the minimum 15V.
Use a power supply with the safety agency approvals for the location.
The provided additional power connector has solder cups, and will work for
wire sizes up to 16 AWG, and an outside cable diameter of .22-.25 inch (5.6-
6.3 mm).
The following illustration shows the polarity of the power connector plug and
the connection on the RF Sensor casing. The connector is a
SF6382-2SG-520.
Mounting Kit
The RF Sensor comes with a mounting kit that allows it to be installed in both
indoor and outdoor locations. Included in the kit are:
Mounting Bracket - Used by itself, this bracket allows the Sensor to be wall
mounted.
The installer is responsible to ensure the wall attachment
can support 15 kg or more.
Pipe Bracket — Connected to the Mounting Bracket, the Pipe Bracket allows
the Sensor to be mounted on either a horizontal or vertical pipe. To mount the
Sensor to a pipe with a diameter equal to or less than 60mm (2 3/8 inches),
use a U-bolt of the appropriate size. To mount the Sensor to a pipe with a
diameter greater than 60mm (2 3/8 inches), use hose clamps of the
appropriate size.
Security Brackets — Connected to the Sensor, they allow it to be secured to
the Mounting Bracket with padlocks. These brackets also bear the weight of
the Sensor while the final screws are installed.
