INSTALLATION
2-5
May 2000
Part No. 001-2008-204
For example, a high-speed diode reacts first,
clamping a voltage strike within 10 ns, a heavy duty
heat coil reacts next to reduce the remainder of the
current surge, and a high-powered three-element gas
tube fires, grounding Tip and Ring.
2.7.1 PROTECTION GUIDELINES
Follow these guidelines for grounding and light-
ning protection. Each Repeater installation site is dif-
ferent; all of these may not apply.
•
Ensure that ground connections make good metal-
to-metal contact (grounding rod, grounding tray,
metal conduit) using #6 gauge solid wire or braided
wire straps.
•
With surge protectors, ensure that ground wires go
directly to ground, and not through other equipment.
•
Run the ground wire for RF coax protectors directly
to ground.
•
With coax protectors, ensure maximum instanta-
neous voltage does not exceed the rated voltage.
•
Do not run ground wires parallel to any other wiring
(e.g. a ground wire parallel to a telephone line),
except other ground wires.
•
Double check all equipment for good ground and
that all connections are clean and secure.
2.8 UNPACKING AND INSPECTION
Transcrypt Internation, Inc. ships the Repeater
securely crated for transportation. When the Repeater
arrives, ensure the crates remain upright, especially if
storing the crates temporarily.
When unpacking the Repeater, check for any visi-
ble damage or problems caused by shipping. If there
is obvious damage from shipping mishaps, file claims
with the carrier. If there appears to be any damage
caused before shipping, file a claim with Transcrypt
Internation, Inc. Contact Customer Service for assis-
tance (see Section1.7).
