Low-Voltage PELV (Class 2: USA) Wiring
Important Notes
•
Install in accordance with all applicable regulations.
•
CAUTION: Do not connect line voltage/mains power to
device. Improper wiring can result in personal injury or
damage to the device or to other equipment.
•
This control can use PELV (Class 2: USA) wiring
methods. Check with your local electrical inspector for
compliance with national and local codes and wiring
practices.

• Make daisy-chain connections to the low-voltage PELV
(Class 2: USA) Data Link terminals on the end of the
Control Interface.
• Do not use T-taps. Run all wires in and out of the terminal
block, or use a short pigtail, as shown below.
• Each terminal accepts up to two #18 AWG (1.0 mm
wires.
