A150 Desiccated Case 1. Function 1.1 Typical Applications The A150 desiccated case is a small, self-contained junction box that allows a sensor to be connected to a continuation cable, a PWENC connector, or a CWS900 wireless sensor connector. Utilizing the A150, a sensor may be incorporated into a wireless sensor network or may be attached to a prewired enclosure. Lid Cable Gland Chassis Mounting Bracket FIGURE 1.
A150 Desiccated Case NOTE It is not recommended to insert more than one wire into each connection on the terminal block. If it is necessary to combine wires, use the 5-position lever nut to combine the wires, and then insert the lead wire from the lever nut into the terminal block. When used with a CWS900, the sensor can be used with sensors measuring analog voltages, frequency, and pulse. The CWS900 can also provide excitation voltage to a sensor through the A150.

A150 Desiccated Case 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.
