CAUTION
FOR YOUR SAFETY
THE INSTALLATION, OPERATION, AND
MAINTENANCE OF THIS EQUIPMENT
SHOULD ONLY BE PERFORMED
BY QUALIFIED PERSONS.
WARNING:
The equipment described in this manual
contains high voltage. Exercise due care
during operation and servicing. Read the
safety summary on the reverse of this page

SAFETY SUMMARY
The following safety precautions must be observed at all times during operation, service, and
repair of this equipment. Failure to comply with these precautions, or with specific warnings
elsewhere in this manual, violates safety standards of design, manufacture, and intended use
of this product. RFL Electronics Inc. assumes no liability for failure to comply with these
requirements.
GROUND THE CHASSIS
The chassis must be grounded to reduce shock
hazard and allow the equipment to perform
properly. Equipment supplied with three-wire ac
power cables must be plugged into an approved
three-contact electric outlet. All other equipment
is provided with a rear-panel ground terminal,
which must be connected to a proper electrical
ground by suitable cabling. Refer to the wiring
diagram for the chassis or cabinet for the location
of the ground terminal.
DO NOT OPERATE IN AN
EXPLOSIVE ATMOSPHERE
OR IN WET OR DAMP AREAS
Do not operate the product in the presence of
flammable gases or fumes, or in any area that is
wet or damp. Operating any electrical equipment
under these conditions can result in a definite
safety hazard.
KEEP AWAY FROM
LIVE CIRCUITS
Operating personnel should never remove
covers. Component replacement and internal
adjustments must be done by qualified service
personnel. Before attempting any work inside the
product, disconnect it from the power source and
discharge the circuit by temporarily grounding it.
This will remove any dangerous voltages that
may still be present after power is removed.
DO NOT SUBSTITUTE PARTS
OR MODIFY EQUIPMENT
Because of the danger of introducing additional
hazards, do not install substitute parts or make
unauthorized modifications to the equipment. The
product may be returned to RFL for service and
repair, to ensure that all safety features are
maintained.
READ THE MANUAL
!
Operators should read this manual before
attempting to use the equipment, to learn how to
use it properly and safely. Service personnel must
be properly trained and have the proper tools and
equipment before attempting to make adjustments
or repairs.
Service personnel must recognize that whenever
work is being done on the product, there is a
potential electrical shock hazard and appropriate
protection measures must be taken. Electrical
shock can result in serious injury, because it can
cause unconsciousness, cardiac arrest, and brain
damage.
Throughout this manual, warnings appear before
procedures that are potentially dangerous, and
cautions appear before procedures that may result
in equipment damage if not performed properly.
The instructions contained in these warnings and
cautions must be followed exactly.

"One Phone Line Connects All Substation Devices"
The RFL 9660 DigitalSwitch provides a convenient way to connect intelligent relays,smart meters, sequence-
of-event recorders,digitalfault recorders (DFRs),or similar devicesto a central intelligentdigitalswitch.Through
the use of third-party software packages, the RFL 9660 is able to communicate with Intelligent Electrical
Devices (IED's). Once connected, the user can access and interrogate up to 32 individually
programmable RS-232 ports.This allows maintenance personnel to instantly access substations from their
desks, without having to make a field trip.
Only a single phone line is required to connect to the RFL 9660; this reduces the number of phone lines
required for polling substation equipment.
By replacing the internal modem with a direct digital interface, the
RFL 9660 can also be connected to an existing substation digital network.

Regular telephone line sharing switches require a
separate modem at each device. For example, an

To eliminateexpensivemodemcosts,the RFL 9660 has
beendesigned to containits own integratedmodem. It's
all that's needed to interface all your recorders, relays,

Rearview, RFL 9660 Digital Switch
Two types of RFL 9660 device port modules are
available:
RS-232 and fiber ring. Each RS-232 device
port module will accommodate up to eight individual
devices, such as relays or meters. Up to four
RS-232
device port modules can be installed in one RFL 9660
and can access up to
32 devices. A typical RS-232
device port module is shown below.
The fiber optic device port module allows up to 32
devices to be connected on to a fiber optic ring. An
RFL 9660 can be equipped with both RS-232 and
fiber optic device port modules. The total number of
device connections cannot exceed
32.

Inorderto preventunauthorizedaccess, the RFL9660
features three different levels of security and an

device port can be protected with a password. The
second leveladdsa log-onpasswordthat mustbe used
when the switch is first called. The third level has a
callback feature that causes the RFL 9660 to call the
user back at a preset telephone location before
