Wiring, Continued
Post Header AMP
GDE161.1N
The GDE161.1N Post Header AMP has two sets of identical contacts as shown in
Figure 27.
• 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. It is recommended that one transformer power no more than 12 actuators.
WARNING:
Installations requiring Conformance
• 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.
• Over current protection for supply lines is maximum 10A.
CAUTION:
It is necessary that the output current properly sustain and operate all
GDE161.1N actuators in a daisy chain configuration.

either the top 3
contacts or the
bottom 3 contacts.
