WARRANTY
The IMUX 2000 Intelligent E1 Multiplexer comes with a five-year warranty from date of shipment for replacement of any
part which fails during normal operation. RFL will repair or, at its option, replace components that prove to be defective at
no cost to the Customer. All equipment returned to RFL Electronics Inc. must have an RMA (Return Material
Authorization) number, obtained by calling the RFL Customer Service Department. A defective part should be returned to
the factory, shipping charges prepaid, for repair or replacement FOB Boonton, N.J.
RFL Electronics Inc. is not responsible for warranty of peripherals, such as printers and external computers. The warranty
for such devices is as stated by the original equipment manufacturer. If you have purchased peripheral equipment not
manufactured by RFL, follow the written instructions supplied with that equipment for warranty information and how to
obtain service.
WARRANTY STATEMENT
The IMUX 2000 Intelligent E1 Multiplexer is warranted against defects in material and workmanship for five years from
date of shipment. During the warranty period, RFL will repair or, at its option, replace components that prove to be
defective at no cost to the customer, except the one-way shipping cost of the failed assembly to the RFL Customer Service
facility in Boonton , New Jersey. RFL warrants product repair from five-years from the date of repair or the balance of the
original factory warranty, whichever is longer.
This warranty does not apply if the equipment has been damaged by accident, neglect, misuse, or causes other than
performed or authorized by RFL Electronics Inc.
This warranty specifically excludes damage incurred in shipment to or from RFL. In the event an item is received in
damaged condition, the carrier should be notified immediately. All claims for such damage should be filed with the carrier.
NOTE
If you do not intend to use the product immediately, it is recommended that it be opened immediately after receiving and

WARNINGS AND SAFETY SUMMARY
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
IMUX 2000E1 RFL Electronics Inc.
July 22, 2008 iv 973.334.3100
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.
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.
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.

Because RFL™ and Hubbell® have a policy of continuous product improvement, we reserve the right to change designs and specifications without notice.
WARNING
YOUR IMUX 2000 TERMINAL MAY BE EQUIPPED WITH
FIBER OPTIC INPUT/OUTPUT MODULES THAT HAVE
FIBER OPTIC EMITTER HEADS. FIBER OPTIC EMITTER
HEADS USE A LASER LIGHT SOURCE THAT PRODUCE
INVISIBLE RADIATION. FIBER OPTIC COMMUNICATION
SYSTEMS ARE INHERENTLY SAFE IN NORMAL
OPERATION BECAUSE ALL RADIATION IS CONTAINED IN
THE SYSTEM. IT IS POSSIBLE DURING MAINTENANCE TO
EXPOSE THE RADIATION BY REMOVING OR BREAKING
THE FIBER. STARING DIRECTLY INTO THE LIGHT BEAM
MAY RESULT IN PERMANENT EYE DAMAGE AND/OR
BLINDNESS. NEVER LOOK DIRECTLY INTO THE LIGHT
BEAM AND BE CAREFUL NOT TO SHINE THE LIGHT
AGAINST ANY REFLECTIVE SURFACE.
THE LASER SOURCE IS A CLASS I LASER PRODUCT
WHICH COMPLIES WITH APPLICABLE FDA, OSHA AND
ANSI STANDARDS.
