Step 2 – Sensor and power connections
•
Connect coax cables to all PD sensors according to correspondent PD sensor
installation manual.
•
Connect a 3-conductor shielded cable to RTD terminals in a motor (or generator)
according to drawings and RTD type. If additional RTD was installed, connect its
leads to RTD cable using appropriate crimping tool. Label all conductors on both
ends. (Check IG documentation! RTD sensor may have been already installed in the
sensor interface board.)
•
Connect Current Sensor using appropriate crimping tool. Label positive polarity
terminal (+) or dot.
•
Connect Voltage Sensor. Label positive polarity terminal (+) or dot.
Note: Do not
connect to PT at this time.
•
Connect the humidity sensor according to its description. A humidity sensor has
three wires: +5 Volt, Ground, and Signal. Make sure that all wires are properly
labeled of both sides. (Check IG documentation! Humidity sensor may have been
already installed in the sensor interface board.)
•
Note: Do not connect 115/230 VAC power at this time
