Before connecting this device to the power line, where required, the protective earth terminal
screws of this device must be connected to the protective earth in the building installation.
LINE VOLTAGE:
Before connecting this device to the power line, make sure the voltage of the power source
matches the requirements of the device. Refer to the device Specifications for information
about the correct power rating for the device.
WARNING:
HIGH LEAKAGE CURRENT. EARTH CONNECTION ESSENTIAL BEFORE CONNECTING
SUPPLY.
If the total leakage current exceeds 3.5 mA, or if the leakage current of the connected loads
is unknown, connect the supplementary ground terminal to a reliable ground connection in
your facility.
Supplementary ground connection
A supplementary ground terminal is provided on the codec to connect the unit to a ground
connection. The ground terminal has an M4 stud with M4 retaining nuts and is compatible
with all grounding wires. Remove only
NUT 2 to connect your ground wire. The ground wire
must have a suitable lug. When refitting NUT 2 ensure that both NUT 1 & NUT 2 are
correctly tightened to establish and maintain a proper earth connection.
WARNING: To Reduce the Risk of Electrical Shock and Fire
1. This equipment is designed to permit connection between the earthed conductor of the
DC supply circuit and the earthing conductor equipment.
2. Equipment connected to the protective earthing of the building installation through the
mains connection or through other equipment with a connection to protective earthing -
and to a cable distribution system using coaxial cable, may in some circumstances
create a fire hazard. Connection to a cable distribution system must therefore be
provided through a device providing electrical isolation below a certain frequency range
(galvanic isolator, see EN 60728-11).
3. All servicing must be undertaken only by qualified service personnel. There are not user
serviceable parts inside the unit.
4. DO NOT plug in, turn on or attempt to operate an obviously damaged unit.
5. Ensure that the chassis ventilation openings in the unit are NOT BLOCKED.
6. Do not operate the device in a location where the maximum ambient temperature
exceeds 50°C (122°F), or is below 0°C (32°F).
7. Be sure to unplug both power supply cords from the wall socket BEFORE attempting to
service the unit.
