CXPS-E3
6.5 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 back of the power system. This is to meet the cooling requirements of the rectifiers and to allow
easy access to the power system components.
6.5.1 Floor mounted systems
Secure the system to a concrete floor using either heavy duty anchors (½" × 2½"), or for wooden floors, heavy-
duty lag screws (5/8" × 2½"). Use appropriately sized flat washers.
If required, use isolation kits to isolate system from the floor.
Secure the relay rack to the overhead cable tray. Alpha does not supply the mechanical details necessary for
overhead support.
The CXPS-E3 power system requires at least 2RU (3.5") of space above the distribution for
tooling access to the load breaker ground connections. Ensure that at least 2RU of space is
open in the relay rack above the CXPS-E3 distribution. Some of this space may be consumed by
the clear plastic cover of the CXPS-E3 in higher ambient temperature environments.
NOTE
