Wiring
All wiring must conform to NEC, and local codes and regulations.
Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers.
Determine the supply transformer rating by summing the total VA of all actuators used.
The maximum rating for a Class 2 step-down transformer is 100 VA.
Table 3 shows the recommended maximum actuators per Class 2 circuit and includes a
safety factor of 80% of the transformer VA. Operating additional actuators requires
additional transformers or separate 100 VA power trunks.
