Mounting
Horizontal/Rack PTPD
1. Select the appropriate bracket mounting points for proper mounting depth within the rack.
2. Attach one bracket to these mounting points with two screws.
3. Repeat with the other mounting bracket on the opposite side of the enclosure.
4. 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 rack or cabinets is available. Contact your Server Technology Sales
Representative for more information.
Vertical PTPD
1. Attach one of the removable flanges to the mount points on the top rear of the enclosure using M4
screws.
2. Repeat with the other flange for the bottom mount points on the enclosure.
3. Attach one mounting bracket to the top flange with one set of screws and washers through each of
the slots in the bracket into the nut plate, as shown in Figure 2.2 (brackets may differ from the
illustration). The slots allow about 1½ inches of vertical adaptability.
4. Repeat with the other mounting bracket on the bottom flange.
5. Attach the top and bottom brackets to your rack.
NOTE: Contact your Server Technology Sales Representative for information regarding custom bracket design and
fabrication services if you are unable to find a suitable manner for utilizing the included mounting brackets.
Connecting to the Power Source
On all 100-120V units and 208-240V units with a total output rating of 30A, the input power cord is
attached to the base of the PTPD unit. On 208-240V units with a total output rating <30, you must first
attach the power cord to the PTPD unit before connecting the PTPD to the power source.
To attach a 230V power cord to the 230V PTPD unit:
1. Plug the female end of the power cord firmly into its connector at the base of the PTPD.
2. Use a screwdriver to tighten the two screws on the retention bracket.
To connect the PTPD to the power source:
Plug the male end of the PTPD power cord into the AC power source.
On power up, PTPD-x0 models perform a self-test and display the results on the terminal screen:
•
The Input Current LED displays ‘On’, then switches to the cumulative input load.
•
The audible alarm and contact-closure output relay are triggered for one second.
