Measurement Wiring; Figure 7 Gps Synchronization Kit - Cortalk RMU5 Generic Installation And Configuration Manual

Figure 7 GPS Synchronization Kit

The RMU5 may be equipped with a GPS receiver to allow for precision synchronized interruption of the rectifier output.
If the RMU5 is equipped with this option, an additional cable for the GPS antenna must be brought into the RMU5
enclosure or attached to the external GPS antenna connector (if conduit is not required). If the external GPS antenna
connector is used, apply self-annealing tape and electrical tape over the GPS antenna connector to seal it against moisture
entry. The GPS antenna must be mounted in an area that has reasonable view of the sky with minimal blockage.

4.2.4 Measurement Wiring

Figure 8 shows a typical wiring installation for the RMU5. If the rectifier interruption feature is utilized, a solid-state
relay should be installed on the primaries of the rectifier transformer to allow the RMU5 to interrupt current flow to the
protected structure. The exact model of relay will be installation dependent and must be appropriately sized to allow for
the power consumption of the rectifier.
The RMU5 may be used to monitor the status of the primary circuit breaker in the rectifier if the circuit breaker is
equipped with monitoring contacts. These contacts may be attached to the DIN pins on the main I/O connector as shown
in the typical installation diagram.
Ensure that main rectifier power is off while performing any wiring on the RMU5.
