LIMITATION OF WARRANTY
The warranty shall not apply to defects resulting from improper or inadequate usage or maintenance by
the buyer, buyer supplied products or interfacing. The warranty shall not apply to defects ｒesulting from
unauthorized modifications or from operation exceeding the environmental specifications of the product or
if the QA seal has been removed or altered by anyone other than TEXIO authorized personnel. TEXIO does
not warrant the buyer’s circuitry or malfunctions of TEXIO products resulting from the buyer’s circuitry.
Furthermore, TEXIO does not warrant any damage occurring as a result of the buyer’s circuitry or the
buyer’s - supplied products.
No other warranty is expressed of implied.
WARRANTY SERVICE
This product must be returned to an authorized TEXIO service facility for repairs or other warranty
service. For products returned to TEXIO for warranty service, the buyer shall prepay shipping charges
toTEXIO and TEXIO shall pay the shipping charges to return the product to the buyer. Refer to section
3.11 for repackaging for shipment.
DISCLAIMER
The information contained in this document is subject to change without notice. TEXIO shall not be liable

TRADEMARK INFORMATION
Microsoft and Windows are trademarks of Microsoft Corporation.
THE FCC WANTS YOU TO KNOW
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.
FCC WARNING
Modifications not expressly approved by manufacturer could void the user authority to operate the
equipment under FCC Rules.

SAFETY INSTRUCTIONS
CAUTION
The following safety precaution must be observed during all phases of operation, service and repair of this
equipment. Failure to comply with the safety precautions or warnings in this document violates safety
standards of design, manufacture and intended use of this equipment and may impair the built-in
protections within.
TEXIO shall not be liable for user’s failure to comply with these requirements.
INSTALLATION CATEGORY
The PU power supply series has been evaluated to INSTALLATION CATEGORY II.
Installation category (over voltage category) II: local level, appliances, portable equipment etc. With smaller
transient over voltage than Installation Category (over voltage category) III.
GROUNDING
This product is a Safety Class 1 instrument. To minimize shock hazard, the instrument chassis must be
connected to an electrical ground. The instrument must be connected to the AC power supply mains
through a three conductor power cable, with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet.
For instruments designed to be hard-wired to the supply mains, the protective earth terminal must be
connected to the safety electrical ground before another connection is made. Any interruption of the
protective ground conductor, or disconnection of the protective earth terminal will cause a potential shock
hazard that might cause personal injury.
FUSES
Fuses must be changed by authorized TEXIO service personnel only. For continued protection against risk
of fire, replace only with the same type and rating of fuse. Refer to maintenance instructions in chapter 9
for fuses rating.
INPUT RATINGS
Do not use AC supply which exceeds the input voltage and frequency rating of this instrument. The input
voltage and frequency rating of the PU power supply series is: 100-240V, 50/60Hz.
For safety reasons, the mains supply voltage fluctuations should not exceed +/-10% of nominal voltage.
WARNING
OUTPUT TERMINAL GROUNDING
There is a potential shock hazard at the RS232/485 and the IEEE ports when using power supplies
with rated or combined voltage greater than 400V and the Positive Output of the Power Supply is
grounded. Do not connect the Positive Output to ground when using the RS232/485 or IEEE.
