Page  76

Figure 32 shows an example of how external equipment could be connected 
through the junction box accessory. 

When connecting external equipment the following procedures should be ob-
served.

• The common line should be connected to the sensor port if one is avail-

able.

• The shield in the cable used to connect the external equipment should be 

connected at one end only, Refer to the manufacturers documentation 
regarding cable construction.

• The chassis connection can be made with EITHER a drain wire OR 

directly to the cable shield using exposed wire links on the junction box 
printed circuit board, depending on the cable construction.
