DC(M)24-(44/88) Series - Installation, Operation & Maintenance Manual Continued
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
total VA of all actuators used. It is recommended that
one transformer power no more than 10 actuators.
Wiring Diagrams
Wiring DC24-44 Series
• All wiring for CE rated actuators must only be separated
extra low voltage (SELV) or protective extra low voltage
(PELV) per HD384-4-41.
• Use safety-isolating transformers (Class III transformer)
per EN 61558. They must be rated for 100% duty cycle.
• Overcurrent protection for supply lines is maximum 10A.
WARNING
Installations requiring Conformance
CAUTION
Do not wire dierent types of actuators (such as Floating & Modulating) in parallel.
