HESE PROCEDURES REQUIRES REMOVAL OF THE ENCLOSURE COVER . T HIS SHOULD BE
DONE ONLY IF THE AREA IS KNOWN TO BE NON - HAZARDOUS .
Connect the proper AC voltage supply to power the ECA at connector J7. Neutral, Earth, and Line
connection points are indicated on the circuit board. For controllers rated at 220VAC, the two line
conductors are wired to the line and neutral inputs. The operating voltage and frequency of the ECA
are factory configured -- an internal motor and capacitor are sized according to voltage and frequency.
If the power supplied to the unit does not match the factory configuration (shown on the nameplate),
the ECA will still operate the internal synchronous motor, eventually causing damage and improper
operation.
To ensure proper operation, the ECA should remain powered at all times. A dry contact input
is provided to provide the ECA with motor status (on vs. off). See Section 4.6.1
High Voltage circuits (e.g., branch) should be run in separate conduit. Do not combine High
Voltage (i.e., greater than 100VAC) lines and Low Voltage (i.e., less than 28VDC) lines in a
common conduit!
