Installation

Grounding

A low impedance connection with a maximum length of 3 m (9.84 ft) must be

 

installed between the splitter box's ground electrode and the reference ground in

 

order to discharge the noise voltages. The inductance of standard grounding cables

 

(PE) presents a risk of high impedance when high frequency noise voltages are

 

present. It is therefore advisable to use grounding strips. If this solution is not

 

possible, use a ground conductor with a large cable cross-section and a ground

 

connection that is as short as possible.

WARNING

RISK OF UNINTENDED EQUIPMENT OPERATION

If the box is not connected to the ground, or if the ground connection is made using an inappropriate cable, the product will be sensitive to electromagnetic disturbances. This may lead to unexpected equipment operation.

Failure to follow this instruction can result in death, serious injury, or equipment damage.

Cable Routing Make sure that the following basic wiring rules are followed:

Keep the data wire and the power cables apart from one another, in so far as is possible.

Make sure there is a space of at least 10 cm (3.94 inches) between the data wires and the power cables.

The data wires and power cables must only cross at a right angle to one another. It is advisable to route the data wires and power cables through separate shielded

￿ducts.

When laying the cables, the noise voltage from other devices or wires must be considered. This particularly applies to frequency converters, motors and other devices or cables generating high frequency disturbances. High frequency sources and the cables described in this manual must be as far apart from each other as possible.

WARNING

RISK OF UNINTENDED EQUIPMENT OPERATION

Please read and comply with the cabling rules listed above. Failure to comply with these wiring rules is a common cause of EMC problems! This may lead to unexpected equipment operation.

Failure to follow this instruction can result in death, serious injury, or equipment damage.
