Practical Cabling Techniques
The following issues must be taken into consideration when installing the Dupline
®
bus cable�
•
Do not mount the Dupline
®
bus cable close to high voltage installations such as:
•
Motors
•
High voltage cable
•
Inverters
•
Breakers
•
Be sure that water cannot penetrate the Dupline
®
bus cable or junction boxes� Water can
cause poor connection and random activations of the sensors�
•
If the cable is installed close to high voltage cables or equipment, use shielded cable�
Placing the Sensor
When installing sensors it is important to investigate what kind of technique is the best in the specific
installation�
The sensors operate at distances between 1�5 m(4�95 feet) and 4�0 m(13�2 feet)� In the planning stage
decisions should be made on where and how to mount the sensors� The decisions based upon physi-
cal conditions will include:
Mounting the ferrules
on the multi core wire
