ELECTRICAL INSTALLATION
For both 24vdc and 90vdc devices:
1. Connect vdc power source to the terminals marked 1, 2.
2. Connect protective grounding circuit* to the terminal marked with the P.E. symbol
*
NOTE: Both the functional-earth and protective-earth connections to ground are mandatory. The protective-earth
ground connection is required for safety and regulatory compliance. The functional-earth ground connection is
required for noise immunity, reliability, and Electromagnetic Compliance (EMC) with the European Union (EU) EMC
directive for CE-mark conformance.
RATED COIL CURRENTS
NOTE: The coil system has been changed from Class A to Class F. Refer to the nameplate on your unit to
determine which insulation class you have. If you have Class F insulation, the nameplate will denote Class F. If you
have Class A, there will be no notation on the nameplate.
