3.2 ELECTRICAL
The sensors are connected to the turbine junction box with a connector cable as specified in Section 1.1. All
wiring must be in grounded conduit or armored. The green wire must be connected to earth ground at the junction
box. Do not connect the shields over the twisted pair signal leads to each other or to earth ground at any location.
The inner shields should be individually jumpered through all junction boxes and connected to the proper ground
terminal at the Controller. The polarity of the cable is: red wire is positive and black wire is negative. The polarity
is shown in the drawings. Reverse polarity will not damage the sensor. Signal cable from the junction box to
the Controller should be 18 gauge (1.02 mm) twisted shielded pair. The extension cable from the junction box
to the Controller is the customer’s responsibility.
