4.3 Detaching the SPACOM relay and making the re-
wiring of retrofit connectors with installation
support frame
The work to retrofit the SPACOM relay can begin when the necessary
safety procedures have been done at site. The auxiliary voltage must
be disconnected before start of the retrofit work. It is recommended to
inspect relay wiring first for any discrepancies.
1. REX615 relays are delivered from the factory with suitable retrofit connectors
installed on the relay terminals. Remove the retrofit connectors X100 and X110,
and also X130 if it is part of the delivery.
Figure 3: Removing the retrofit connectors
Retrofit connectors can be installed to the corresponding terminals of the
installation support frame, if it has been part of the delivery.
