Securing the Power/Distribution Shelf to a Relay Rack or Cabinet
The shelf is designed to mount in a standard 19” or 23” wide relay rack or cabinet frame having 1” or 1-3/4”
multiple drillings. Refer to SAG582136700 for overall dimensions and a list of available relay racks.
NOTE!
Refer to the General Requirements section at the beginning of this section for Ventilation
Requirements.
NOTE!
Multiple Power/Distribution Shelves may be stacked one above the other with no space between
the shelves.
Mounting the Shelf
1.
Secure shelf mounting angles to relay rack or cabinet at two (2) locations per side. Use grounding
washers at one (1) location per side. Proper orientation of grounding washers enables teeth to dig into
paint for a secure ground connection. Torque connections to 70 in-lbs.
NOTE!
Compliance with Telcordia GR-1089-CORE requires that prior to mounting the
Power/Distribution Shelf to the equipment rack:
•
All paint must be removed from the front surface of each equipment rack rail where it mates with a
shelf-mounting bracket, so that good metal-to-metal contact can be established between the shelf
and rack.
•
The shelf-to-rack mating surfaces must be cleaned.
•
Electrical anti-oxidizing compound must be applied to the shelf-to-rack mating surfaces.
