Connection in outdoor applications
Safety precautions:
Coax grounding: If an outside cable system is connected to the unit,
ensure that the system is grounded.
U.S.A. models only - Section 810 of the National Electrical Code, ANSI/
NFPA No.70, provides information regarding proper grounding of the
mount and supporting structure, grounding of the coax to a discharge unit,
size of grounding conductors, location of discharge unit, connection to
ground electrodes, and requirements for the grounding electrode.
Power lines:
An outdoor system should not be located in the vicinity of
overhead power lines, electrical lights, or power circuits, or where it may
contact such power lines or circuits. When installing an outdoor system,
extreme care should be taken to keep from touching power lines or circuits,
as this contact may be fatal. U.S.A. models only - refer to the National
Electrical Code Article 820 regarding installation of CATV systems.
24 VAC power source:
This unit is intended to operate with a limited power
source, this power source must comply with EN60950. When the unit is
intended to operate at 24 VAC, normal input voltage is between 12 VAC and
28 VAC. Voltage applied to the unit's power input should not exceed 28 VAC.
User supplied wiring, from 24 VAC supply to unit, must be in compliance
with electrical codes (Class 2 power levels). Do not ground the 24 VAC supply
at the terminals or at the unit's power supply terminals.
Connection: The unit has
connection terminals on flying
leads. In wet or outdoor
installations make use of the
VDA-455SMB accessory or use a
field wiring box with Nema3 or
IP55 protection level or better.
Make the connections inside the
water tight compartment. After
connections are made ensure that
the watertight compartment is
tightly closed and cables and
conduits are properly sealed to
prevent ingress of water.
