APC Step-Down Transformer
Models: AP9626, AP9627, and AP9628
990-7820F
06/2006
Introduction
Introduction
The APC® step-down transformers are used to convert a higher input voltage (208-200 V) to a lower output
voltage (120-100 V) which might be more fitting for certain environments or system configurations.
Note: Illustrations in this document may vary from your actual configuration.
Unpacking
Read the Safety Guide before installation.
Note: The model and serial numbers are located on a small, rear panel label. For some models, an additional
label is located behind the front bezel.
Inspect the transformer upon receipt. Notify the carrier and dealer if there is damage.
The packaging is recyclable; save it for reuse or dispose of it properly.

Introduction
Electrical Specifications
Attention:
• Operation above the input voltage range may cause equipment damage.
• Operation below the input voltage range may cause overload or automatic shutdown. When
connecting directly to a branch circuit, check that the line voltage is within specifications. When
connecting to the UPS, check that the line voltage into the UPS is within specifications before
transferring to bypass mode.
Note: In order for AP9626 models to output the full 5000 VA, the input must be hardwired to a 5500 VA source.

Attention:
•
The AP9626 and AP9627 models DO NOT require hardwiring. Use the attached cord to connect
to utility power. For optional AP9626 hardwiring, follow wiring instructions below.
Hardwiring
Attention:
• All electrical configurations must be performed by a qualified electrician.
• Adhere to all local and national electrical codes.
• Verify that all branch circuit (mains) are de-energized and locked out before installing cables or
making connections.
• Use 10-gauge (6 mm2) wire.
1. Switch the transformer input circuit breaker and the utility circuit breaker OFF.
2. Remove the access panel, by removing screws (see A for AP9626 models and B for AP9628 models).

3. For AP9626 models only, disconnect the power cord from the terminal blocks.
4. For AP9628 models only, remove circular knockouts.
5. Install a flexible type conduit for input and output (AP9628 models only) panels, and secure.
6. Run wires through the conduit.
7. Connect the new wires to the terminal blocks (see the terminal blocks for AP9626 models and AP9628
models below). Wire to the ground block first. Each terminal block is labeled.

Attention:
• Wiring must be performed by a qualified electrician.
• Adhere to all local and national electrical codes.
• If the internal temperature of the transformer is less than 100ºF, one of the fans is at risk of
failing. If 100ºF is reached, the redundant fan will turn on.
1. Check that all power is turned OFF.
2. For AP9626 (optional) or AP9628 models only, hardwire the transformer (see Hardwiring).
3. For AP9626 or AP9627 models only, connect all load equipment to the PDU receptacles.
Note: Each receptacle group is protected by a circuit breaker. A colored label identifies each circuit and the
corresponding breaker.
4. Switch the transformer input circuit breaker ON.
5. Turn on output circuit breakers as needed.
6. Turn on all connected equipment.
