Mounting

1.Select the appropriate bracket mounting points for

proper mounting depth within the rack.

2. Attach the brackets to these mounting points with two screws for each bracket.

3. Install the enclosure into your rack, using the slots in each bracket. The slots allow about ¼ inch of horizontal adaptability to align with the mounting holes of your rack.

NOTE: A mounting bracket kit for 23” wide racks or cabinets is available. Contact your Server Technology Sales Representative for more information.

Connecting to the Power Source

The input power cord must first be attached to the unit before connecting the unit to the power source. Each outlet powers up sequentially, eliminating a potential blown primary fuse or circuit breaker from excessive in-rush current.

To attach the power cord to the unit:

1.Plug the female end of the power cord firmly into its connector at the base.

2.Use a screwdriver to tighten the two screws on the retention bracket.

To connect to the power source:

Plug the male end of the power cord into the AC power source.

Connecting Devices

To avoid the possibility of noise due to arcing:

1.Keep the device’s on/off switch in the off position until after it is plugged into the outlet.

2.Connect devices to the PT22 outlets.

NOTE: Server Technology recommends even distribution of attached devices across all available outlets to avoid exceeding the outlet, branch or phase limitations. See Power Ratings on page 69 for more information.

Always disconnect both power supply cords before opening to avoid electrical shock. Afin d’éviter les chocs électriques, débranchez les cables électrique avant d’ouvrir.
