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

E.F. Johnson 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 E.F. Johnson.
Contact Technical Service for assistance (see Section
1.7).
If everything appears undamaged, remove the
Repeater equipment from the crate, using normal pre-
cautions for unpacking.
NOTE: Do not discard the packing materials. If you
must return an item, use the same packing materials
and methods (including static protective bags for cir-
cuit cards) to repack the equipment. You are responsi-
ble for proper repacking. E.F. Johnson cannot be
responsible for damage to equipment caused by negli-
gence.
NOTE: Repeaters should not touch. Leave a mini-
mum of one empty screw hole (approximately 1/2")
between repeaters vertically, especially for bottom
ventilation slots in high power repeaters.
NOTE: Each repeater should be grounded separately
by connecting a ground bus from the ground lug on the
back side of the RF module to the ground bar on the
rack (see Figure 2-7).
