IMPROPER CONNECTION OF LOAD
For safety reasons, the loads must be connected connected between terminals 2-8 and
between terminals 2-25 .
Failure to comply with these instructions could result in death or serious injury.
MANUAL RESTART
• The restart contact can be provided by the press cycle start command.
•
The effective restart of the module is achieved 30 ms after the push-button is released,
and after a short pulse (between 0.1s and 1s) is sent on the restart input of the module.
