Spare Connections
The HRE-506 stub has three spare pairs and one order wire pair. One spare pair and the order wire pair are in the
blue group. The remaining two spares are in the orange group.
Order Wire Connections
The external order wire pair access port is connected to its surge protector by the red-brown jumper wire. The
black and white order wire pair also terminates on this protector. This permits access to the order wire without
opening the enclosure. Simply unscrew the order wire protective cap, as shown in
, to expose
the order wire terminals.
The tube and fitting assembly is also called an Express Air Connection Fitting, which is not
supplied by ADC.
