System Installation
System Installation
SEL-FR12
The SEL-FR12 uses two 10-position control (DIP) switches to set the wireless
network identification (Network ID) of the associated SEL-FT50 Fault
Transmitters, the baud rate and addresses for the MIRRORED BITS serial
communications port, and the separate receiver gain values for the SEL-FT50
Fault Transmitters.
The control (DIP) switch assignments are listed on the SEL-FR12 enclosure.
The switch positions are labeled 1 through 20, but only 1 through 14 are used.
Physical Installation
Install the SEL-FR12 first for easier commissioning when you install the
SEL-FT50 Fault Transmitters.
For simplest installation, place the SEL-FR12 inside the recloser control
cabinet, powered by the 12 Vdc auxiliary power supply of the SEL-651R.
However, it can be installed with any device that communicates through
M
IRRORED BITS. The SEL-FR12 must be connected to an antenna that is
outside the recloser control cabinet and can connect to a coaxial cable run with
proper grounding and lightning protection devices. The antenna is typically
mounted higher up on the pole in a safe location. The appropriate antenna type
is site-specific. Perform a path study before choosing the antenna.
The SEL-FR12 serial port connects to one of the serial ports of the SEL-651R
that are configured for SEL M
IRRORED BITS communications. This
connection allows the SEL-FR12 to share the received fault with the recloser
control. The programmable logic of the recloser control is configured to
incorporate the received data as part of the protection or control decisions.
Installation details differ slightly for SEL-FR12 Fault Receivers placed in
substations.
Refer to the SEL Radios Accessories Guide on the SEL website for a complete
list of radio accessories offered by SEL.
Mounting the SEL-FR12
Use the accessory kit hardware to mount the SEL-FR12 in the recloser control
cabinet. When ordered as an accessory to the SEL-651R, the unit comes pre-
installed without wiring as part of the cabinet.
Chassis Ground and Power Connection
Connect the rear-panel grounding terminal (labeled with the ground symbol)
to a rack frame ground or main station ground for proper safety and
WARNING

CAUTION
Equipment components are sensitive to electrostatic discharge (ESD).
Undetectable permanent damage can result if you do not use proper
ESD procedures. Ground yourself, your work surface, and this
equipment before removing any cover from this equipment. If your
facility is not equipped to work with these components, contact SEL
about returning this device and related SEL equipment for service.
ATTENTION
Les composants de cet équipement sont sensibles aux décharges
électrostatiques (DES). Des dommages permanents non-décelables
peuvent résulter de l’absence de précautions contre les DES.
Raccordez-vous correctement à la terre, ainsi que la surface de travail
et l’appareil avant d’en retirer un panneau. Si vous n’êtes pas équipés
pour travailler avec ce type de composants, contacter SEL afin de
retourner l’appareil pour un service en usine.
