4.3 Power system assembly and mounting
The power system must be mounted in a clean and dry environment. Sufficient free space must be provided at
the front and rear of the power system. This is to meet the cooling requirements of the rectifiers and to allow easy
access to the power system components.
NOTE: The distribution center requires at least 1RU (1¾") of space above the unit to access to the load breaker ground
connections. Ensure that at least 1RU of space is open in the relay thread above the distribution center.
NOTE: The power system is suitable for installation in Network Telecommunication Facilities, locations where the NEC
applies, and OSP applications.
4.3.1 Rack mounted systems
Attach the power system to the customer-provided relay rack using thread-forming mounting screws and star
washers to ensure an electrical bond between the system chassis and relay rack.
The system may be mounted into a 19" rack in either a flush or center mount position. Use the 19"-to-23" rack
adaptors to mount into a 23" rack.
4.3.2 Floor mounted systems
Secure the system to a concrete floor by using heavy duty anchors (½" x 2½"). For wooden floors, use heavy-duty
lag screws (5/8" x 2½"). Use appropriately sized flat washers.
If required, use isolating kits to isolate the power system from the floor.
Secure the relay rack to the overhead cable tray. Alpha does not supply the mechanical parts needed for
overhead support.
