Overview
Enclosure Front
Serial and Ethernet
Patch Cables
Socket-based compact enclosures have patch cables connected to the
communications ports at the back of the SEL-734B.
If an SEL-3060 radio is installed in the enclosure, the Ethernet port is
connected to the radio; otherwise, an RJ45 Ethernet patch cable is accessible
from the front of the enclosure.
Two serial patch cables connect to PORT 2 and PORT 3 of the SEL-734B. The
patch cables are accessible from the front of the enclosure. The cables have a
male DB-9 connector, and one female/female DB-9 gender changer is
provided with the enclosure.
Front Door Label
Socket-based compact enclosures provide a schematic diagram on the inside
of the enclosure door. The following information is also included on the label:
➤ Serial number
➤ Model option number
SEL-3060 Ethernet
Radio
Socket-based compact enclosures are available with the SEL-3060 Ethernet
Radio. When the enclosure is ordered with the radio, SEL installs an N-type
surge arrestor on the bottom of the enclosure to allow connection of an
antenna. The antenna and cable are sold separately.
SEL-3031 Serial Radio
Full-size enclosures with the combined sensor connector are available with the
SEL-3031 Serial Radio pre-installed. The antenna, cable, and N-type surge
arrestor are sold separately.
SEL-2401 Satellite-
Synchronized Clock
Compact Enclosure
Socket-based compact enclosures are available with the SEL-2401 Satellite-
Synchronized Clock. Enclosures ordered with the SEL-2401 come with a low-
profile satellite antenna on top of the enclosure and the SEL-2401 output
connected to the IRIG-B input on the SEL-734B.
Full-Size Enclosure With Combined Sensor Connector
Full-size enclosures with the combined sensor connector are available with the
SEL-2401 pre-installed. Enclosures ordered with the SEL-2401 come with the
SEL-2401 output connected to the IRIG-B input on the SEL-734B and a
TNC-type surge arrestor and connector installed on the bottom of the
enclosure to allow for connection of a satellite antenna. The antenna and cable
are sold separately.
Open Door
Indications
Some enclosure models have a door switch wired to a digital input on the
SEL-734B. The digital input changes state when the door is opened and the
indication is mapped to the DNP Binary Inputs for SCADA. Check the
ordering option of your enclosure to determine if your model supports an open
door indication switch.
