This manual contains important instructions that should be followed during installation and maintenance
of the STEP-DOWN TRANSFORMER
The Smart App Online OL6KSTF and OL10KSTF step-down transformer models that are covered in

SPECIAL SYMBOLS
Warning: High voltage – Risk of Electric Shock
Caution - Important Instructions: must always be followed.
Do Not Discard: the UPS or UPS batteries in trash. The batteries
contain lead acid. For more information, contact your local recycling
or hazardous waste facility.
The AC electrical service where the step-down transformer is connected should be
close to the unit and easily accessible.
Please use only UL-marked mains cable, (e.g. the mains cable of your equipment), to
connect the step-down transformer to the AC outlet.
Please use only UL-marked power cables to connect any equipment to the step-down
transformer.
Do not unplug the unit from AC power during operation, as this will disconnect the
protective ground insulation.
Do not use an improper size power cord as it may cause damage to your equipment
and cause fire hazards.
Make sure everything is turned o and disconnected completely before conducting
any maintenance, repairs or shipment.
Installation environment should be in a temperature and humidity controlled indoor
area free of conductive contaminants. Do not install this step-down transformer
where excessive moisture or heat is present (Please see specifications for acceptable
temperature and humidity range).
Never install a step-down transformer, or associated wiring or equipment, during a
lightning storm.
Do not work alone under hazardous conditions.
Input circuit breaker must be “OFF” during the building installation.
Only qualified maintenance personnel should perform this task.
Before connecting to the step-down transformer, check that the input voltage into
the step-down transformer is within specifications.
DO NOT INSTALL THE STEP-DOWN TRANSFORMER WHERE IT WOULD BE EXPOSED
TO DIRECT SUNLIGHT OR NEAR A STRONG HEAT SOURCE!
DO NOT BLOCK OFF VENTILATION OPENINGS AROUND THE HOUSING!
DO NOT CONNECT DOMESTIC APPLIANCES SUCH AS HAIR DRYERS TO STEP-DOWN
TRANSFORMER OUTPUT SOCKETS!
RISK OF ELECTRIC SHOCK
To prevent the risk of fire or electric shock, only use the supplied hardware to attach
the mounting brackets.
Remove watches, rings or other metal objects. Use tools with insulated handles.
The step-down transformer must be connected to a grounded AC power source with
fuse or circuit breaker protection. DO NOT plug the step-down transformer into an
outlet that is not grounded. If you need to power-drain this equipment, turn o and
unplug the unit.
(No User Serviceable Parts): Risk of electric shock, do not remove cover. No user
serviceable parts inside. Refer servicing to qualified service personnel.
To prevent the risk of fire or electric shock, install in a temperature and humidity
controlled indoor area, free of conductive contaminants. (Please see specifications for
acceptable temperature and humidity range).
To avoid electric shock, turn o and unplug the unit before installing the input/output
power cord with a ground wire. Connect the ground wire prior to connecting the line wires!
Connect the Protection Earth (PE) safety conductor before any other cables are
connected.
PRODUCT SAFETY
RISK OF ELECTRIC SHOCK
The step-down transformer should be placed near the connected equipment and
easily accessible.
All step-down transformer models covered in this document are permanentlyconnected equipment and only qualified maintenance personnel may carry out
installations.
Wiring must be done by qualified personnel.
DO NOT USE FOR MEDICAL OR LIFE SUPPORT EQUIPMENT! Under no circumstances
should this unit be used for medical applications involving life support equipment and/
or patient care.
DO NOT USE WITH OR NEAR AQUARIUMS! To reduce the risk of fire, do not use with
or near aquariums. Condensation from the aquarium can come in contact with metal
electrical contacts and cause equipment to short out.

The CyberPower Step-Down and Isolation Transformers support hardwire installations (OL6KSTF/ OL10KSTF) and are designed for a variety of CyberPower UPS systems. When connected to a UPS, the step-down
transformer converts voltage from 200-240V down to 100-120V.
UNPACKING PROCEDURES
Information, advice, help
The UPS system is very heavy, please handle with care. Wear safety shoes and use a hydraulic equipment
lift if one is available. At least two people are required for all handling operations, including unpacking,
lifting, and installation in a rack system. Do not use the lifting straps to carry the unit around; they are
provided to manually unpack the unit only.
Attach two rack mount ears to the step-down transformer using eight black M5X7L flat head screws. Install
hanging brackets using six silver M5X6L pan head screws.

Step 3: Rackmount rail Installation
The rails adjust to mount in 19 in (48 cm) racks from 20.5 in to 36 in (52 cm to 91.5 cm) deep. Select the
proper holes in the rack for positioning the step-down transformer in the rack. The step-down transformer
takes up 2 rack units: rack hole positions 1 through 6.
Position the guide screws on the back of the rackmount rails into the rear rack square holes to temporarily
support the rails in place.
Step 4: Adjust rackmount rails to fit your rack
Adjust the rail depth to match your rack depth. Attach the rackmount rail to your rack with two black
M5X6L pan head screws and two plastic washers at the front of the rack (square holes 1 and 4 as shown
below). Secure the rail to the rear of the rack with two black M5X12L screws and two plastic washers.
Step 5: Place and secure the step-down transformer on the rails
Slide the hanging brackets on the step-down transformer on to the rails mounted in the rack with the front
of the unit facing toward you. Secure the step-down transformer to your rack with four black M5X12L pan
head screws at the front of the rack (square holes 1 and 4 as shown above).
NOTE: To slide the step-down transformer out from the rack
The step-down transformer will be secured by a safety locking mechanism midway of pulling it out of the
rack. Use both hands to hold the step-down transformer and press the safety locking tab to pull the stepdown transformer out.
Adhere the protective rubber pads to the left hand side of the step-down transformer.
Step 2: Attach the base stands and attach the dust covers
Stand the step-down transformer on its side with the rubber pads facing down. Install dust covers on open
screw holes. If installing the step-down transformer together with a UPS and Extended Battery Module
(EBM) secure the tie plate between the UPS, EBM and the step-down transformer using four black M5X7L
flat head screws. Optionally adhere four circular rubber pads to each rack mount ear to use as tower stands
and screw them on to the EBM and the step-down transformer using four silver M5X6L pan head screws for
added stability as shown below.
Loosen the two screws joining the top and bottom terminal block covers to separate them.
Step 2: Secure the bottom cover on to the step-down transformer
Tighten the two screws to secure the bottom cover on to the step-down transformer terminal block.
Step 3: Input/Output configuration
Insert the input/output cables through the appropriate cable gland. Hardwire the input/output wiring to
their respective terminals as shown in the terminal block identification and configuration table.
Step 4: Secure the top cover
Use four screws to secure the top terminal block cover on to the step-down transformer.
