1—Introduction
Congratulations on your purchase! Power Innovations has designed this product to ensure excellent quality and
durability. The Chameleon 4.4. comes to you ready to be installed.
1.1—Product Overview
The Chameleon™is a product family of 19-inch rack mounted transformers that provide power conversion and
distribution in a data center environment. This manual covers the 4.4 kVA auto-transformer module. Up to two 4.4 kW
modules can be installed in a 2U 19-inch rack space for a total of 8.8 kW per shelf (a separately sold accessory). When
using a shelf with only one transformer installed, an accessory Blank Plate may be purchased.
1.1.1—Key Product Features
•Power conversion from 277 VAC to 240 VAC single phase.
•Up to two 4.4 kW transformers per shelf for a total of 8.8 kW in 2U of rack space.
•Output Power Distribution with IEC 60320 C19 locking connectors.
•Full downstream power protection with secondary distribution breakers.
•Extended product life (see Warranty at the back of this manual).
1.1.2—Auto-Transformer Module Product Specification Summary
•Input Receptacles: One 277 VAC INPUT connection for each transformer module via a locking
Anderson Power Products Saf-D-Grid 3000 600V PN 2326G4-BK, Key B, Black receptacle. User
supplied INPUT cables should mate with this receptacle.
•Output Receptacles: Two 240 VAC connections per transformer module using C19 locking
mechanisms to keep cables secure. No locking mechanism required on the user supplied cables.
•Circuit Protection: Each OUTPUT receptacle has its own branch rated circuit protection.
•Captive Screws on the rear of each shelf hold the transformers in place.
•Ventilation: Each module features a fan exhaust system. A 24 VDC power supply provides power to
fan.
•Fuse Protection: A slow blow fuse protects the 24 VDC power supply. It can be easily accessed and
replaced from the rear of each module (Figure 6).
1.1.3—Product Accessories
•Shelf: the shelf is designed to hold one or two transformer modules and be placed on user-supplied
L-bracket rails.
•Blank Plate: The Blank Plate is an air dam that can be used to block air flow through the other side of
a shelf that houses only one transformer module.

2—Installation
2.1—Shelf Installation
2.1.1—Rail Installation
If the shelf is being installed in a rack, appropriate rails that support at least 120 lbs. should be installed prior to
mounting the shelf to the rails (section 2.1.2—Shelf Installation).
2.1.2—Shelf Installation
The Shelf is intended be installed in a 2U rack
before the auto-transformer modules are
installed. Install the Chameleon™4.4 SHELF
using standard rack mounting hardware, e.g. 10-
32 pilot screws (user provided).
2.2—Auto-Transformer Modules
The Chameleon™4.4 Shelf supports up to two auto-transformer modules (Chameleon 4.4-TRX-020P2A00).
ELECTRICAL WARNING
Always verify that the Chameleon and any OUTPUT devices are OFF before
adding/removing an OUTPUT device.
2.2.1—Installing an Auto-Transformer Module
1. Verify all the Chameleon™4.4 breakers are OFF (Open).

2. Push the module into the shelf until the rear of the transformer touches the two brackets on the rear of the
shelf (Figure 2).
3. Fasten the transformer module to the shelf by tightening the two captive screws per module (Figure 2).
4. Connect a user provided compatible C19 (section 1.1.2) OUTPUT cable into J1 or J2 (Figure 3) at the
back of the module. The OUTPUTs J1 and J2 correspond with their respective breakers, S1 and S2
(Figure 4).
5. Connect a user provided INPUT cable compatible with an Anderson Power Products Saf-D-Grid 3000
600 V PN 2326G4-BK, Key B, Black receptacle.

2.2.2—Removing an Auto-Transformer Module
1. Verify all the Chameleon™4.4 breakers are OFF.
2. Disconnect all cables from the Module.
3. While at the rear of the cabinet, unscrew the captive screws at the rear of the transformer module and pull
the handle to help remove the module (Figure 4) from the shelf.
4. Remove the module from the shelf remembering to support the module from underneath.
2.2.3—Blank Plate
If a module space remains empty, a Blank Plate may be purchased from Power Innovations to act as an air dam
for the rack. Follow these instructions to install the Blank Plate:
1. Gently place the Blank Plate into position at the front of the Shelf (Figure 5).
2. Press the Blank Plate at the pressure points shown in Figure 5 into the Shelf until it snaps in place.

2.3—Connecting/Disconnecting a PDU or Output Device to the Module
2.3.1—Adding an Output Device/Load
1. Verify that all connected devices are OFF.
2. Verify that the Chameleon™4.4 secondary breakers (S1, S2) associated with the OUTPUT receptacles
(J1, J2) are OFF.
3. Plug in the device with a user supplied C19 INPUT cable.
4. Turn ON the secondary breaker (S1 or S2) for its respective receptacle (J1 or J2).
2.3.2—Removing a Connected Device
1. Verify that all connected devices are OFF.
2. Verify that the Chameleon™OUTPUT breaker associated with the OUTPUT receptacle is OFF.
3. Carefully unplug the device from the OUTPUT receptacle by pressing the red C19 disconnect button.

3—Operation
3.1—System Breakers
The Chameleon™4.4 is equipped with a 20-amp INPUT breaker and two 20-amp OUPUT breakers (S1-S2).
3.1.1—Startup
1. Turn ON the 20-amp MAIN breaker (INPUT breaker).
2. Turn ON the desired 240 VAC OUTPUT breakers.
Once the startup procedure is complete, the Chameleon™4.4 should be left ON during normal operation. An
OUTPUT device can be turned ON or OFF without using the Chameleon OUTPUT breakers.
3.2—Maintenance
The Chameleon is designed for maintenance-free operation and requires very little attention from users.
Caution
There are no user-serviceable parts inside. DO NOT remove the cover or attempt to service the
Chameleon. Unauthorized service will void the warranty laid forth in this manual.
3.2.1—User Serviceable Components
There are no user servable components in the Chameleon™4.4 auto-transformer modules except for the slow
blow fuse (section 3.2.1.1). If there is a problem, replace the transformer with a spare and call Power Innovations
for an RMA number. Then return the unit to Power Innovations noting the RMA number.
3.2.1.1—Slow Blow Fuse
If the fan’s Slow Blow Fuse (Figure 6) needs to be replaced, simply press in on the fuse and turn
counterclockwise until the fuse holder releases. Replace the blown fuse using a 1 amp, 250 VAC replacement
fuse (Figure 6).

3.2.2—Cleaning
To ensure trouble-free operation, keep the unit clean by dusting the cover with a dry cloth. Keep vents clear of
dust and build-up.
3.3—Troubleshooting
Due to its unique design, the Chameleon must be serviced only by authorized personnel, except for the fan fuse (see
section 3.2.1.1—). If the unit fails to operate properly, contact Power Innovations customer support.
If there is a problem with the Chameleon, refer to Table 1, Troubleshooting Guide before contacting Customer Service. If
the problem cannot be resolved, contact Power Innovations Customer Service at 801-785-4123.
