User Manual English 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.
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.
Rack Installation Rack Installation Install the Rails For details on support rail installation, refer to the instructions in the rail kit. Install the Transformer Attention: Install the transformer directly above the UPS.
