Wiring
All wiring must comply with applicable electrical codes and ordinances, or as specified on installation wiring dia-
grams. Device wiring is terminated to the screw terminal blocks located on the top and the bottom of the device.
WARNING
Electrical shock hazard can cause severe injury, death or property damage. Disconnect power
supply before beginning wiring or making wiring connections, to prevent electrical shock or
equipment damage.
The 24 VAC power from an energy limited Class II power source must be provided to the controller and device. To
conform to Class II restrictions (U.S. only), the transformer must not be larger than 100 VA.
IMPORTANT
•
Power must be off prior to connecting to or removing connections from the 24 VAC power
(24 VAC/24 VAC COM), earth ground (EGND), and 20 VDC power (20 VDC) terminals.
•
Use the heaviest gauge wire available, up to 14 AWG (2.0 sq mm), with a minimum of 18
AWG (1.0 sq mm), for all power and earth ground wiring.
• Screw-type terminal blocks are designed to accept up to one 14 AWG (2.0 sq mm) con-
ductor or up to two 18 AWG (1.0 sq mm) conductors. More than two wires that are 18
AWG (2.0 sq mm) can be connected with a wire nut. Include a pigtail with this wire group
and attach the pigtail to the terminal block.
•
If the device is not connected to a good earth ground, the device's internal transient pro-
tection circuitry is compromised and the function of protecting the device from noise
and power line spikes cannot be fulfilled. This could result in a damaged circuit board
and require replacement of the device. Refer to installation diagrams for specific wiring.
