5. Installation

5.1 Mounting

The A150 provides two options for mounting. The first is to use the Velcro

®

strap included with the A150. This allows the A150 to be secured to a small
mast, fencepost or other location where it is not possible to use mounting
screws.

The second option is to use the mounting bracket on the back of the A150.
This bracket allows the A150 to be mounted inside an enclosure or to another
flat surface, using two screws through the bracket to secure the A150.

5.2 Wiring

To wire a sensor to the A150, route the sensor cable through the cable gland
and attach each wire to the terminal block adjacent to the corresponding wire to
the datalogger or CWS900. Use the lever nut to combine multiple ground
wires into a single wire connection. Consult the documentation included with
the sensor, or contact a Campbell Scientific Applications Engineer, for the
correct placement of each wire.

Once all wires are attached, tighten the wire gland to prevent water or
contaminants from entering the A150. Place a desiccant pack, included with
the A150, inside the chassis. Also place the humidity indicator card inside the
A150, and then secure the lid in place with the four captured screws.
