Preinstallation RF-Orchestra!™ Transmitter Installation and Operation
3-10 6880493G02-C July 2000
The paging station is classified as a surge producer because of external coaxial cable
connections. Surges from outside the site can enter the site grounding system through the
coaxial cables. To prevent damage to the equipment, each cabinet must be connected to chassis
ground through a minimum wire size of at least #2 AWG. Green insulated wire must be used
to identify ground wiring.
Cable Tray Grounding
The cable tray assembly must not come into contact with metal conduits, pipes, or other metal
objects. The cable tray assembly must also be connected to the master ground bar through a
single dedicated wire. The connecting wire shall be a minimum size of #6 AWG green
insulated copper wire.
Any metal-to-metal joints on the cable tray assembly must be bonded together with a wire
jumper to prevent electrical discontinuity, unless the tray connectors are specifically designed
to ensure continuity. Painted surfaces on the cable tray assembly must be scraped clean at the
point where the jumper wire is attached to ensure a good electrical connection. Repaint cable
tray assembly surfaces, if necessary.
