NOTES
1. Phase synchronization of AC-load
switching
In case of switching the contact synchronized with phase of load voltage, the life of
contact might be shorter or contact failure
might be caused. Please confirm this
matter in the actual system in this case. If
necessary, the phase control would be
recommended.
