Change-over contact
A potential-free change-over contact is located on the rear panel
of the PROTECT D series to provide for external, potential-free
signaling to a e.g. building services management system. For the
exact pin allocation, refer to the label next to the base. The
contact load is 250Vac 3A, respectively 30Vdc 3A.
Depending on the application, different messages can be
allocated to the contact using the operating panel (see Chapter
7.3.6 on pg. 49ff "Relay configuration").
Use a flexible wire with a cross section of min. 0.5 mm
max. 2.5 mm
the base by tightening the outer screws.
