• 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

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 Customer Service for assistance (see Section

1.8).

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

negligence.

NOTE: Repeaters should not touch, leave a minimum

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).
