PERSONAL SAFETY

CAUTION

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 off 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. 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 off 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 off 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. Internal circuit configuration or equivalent. Installation instructions shall carry sufficient information, including the basic internal circuit configuration of the UPS, to emphasize its compatibility with power distribution systems. Signaling circuit connection – Information shall be provided in the installation instructions as to the purpose and connection of any signaling circuits. For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and shall be easily accessible. For Permanently Connected Equipment:

• A readily accessible disconnect device shall be incorporated in the building installation wiring for AC Input.
• CAUTION – To reduce the risk of fire, connect only to a circuit provided with 30 A maximum branch circuit overcurrent protection in accordance with the National Electrical Code, ANSI/NFPA 70 and the Canadian Electrical Code, Part I, C22.1.
• Wiring Information: Use No. 10 AWG, minimum 90°C copper wire and 18 lb-in Torque force when connecting to AC wiring terminal.

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 permanently- connected 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 unit has a dangerous amount of voltage.

INTRODUCTION

The CyberPower Step-Down and Isolation Transformers support hardwire and power cord installations OL5KSTF and are designed for a variety of CyberPower UPS systems. When connected to a UPS, the step-down transformer converts voltage from 208V down to 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.
USE LIFTING STRAPS TO REMOVE UNIT FROM THE BOX.

HARDWARE INSTALLATION

RACKMOUNT INSTALLATION FOR 4-POST RACK

Caution: Important Instructions

To prevent the risk of fire or electric shock, only use the supplied hardware to attach the mounting brackets.

• Step 1: Rackmount ear & hanging bracket installation
  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 2: 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 3: 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 4: 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 step- down transformer out.

RACKMOUNT INSTALLATION FOR 2-POST RACK
This unit can be installed in a 2-post rack with an optional CyberPower 2-post mounting kit (model: 2POSTKIT, sold separately). See the instructions included with the rail kit for installation procedures.
