In the control cabinet: Connecting the SPECTOR
control
CANopen devices are connected via the CAN interface.
Use a cable with D-subminiature connector (to DIN 41652) as the data cable.
Use a shielded, multi-core, twisted-pair control cable, e.g. UNITRONIC

BUS CAN 2 x 2 x .. mm

Note
The type and preparation of the data cable have a considerable influence on the electro-
magnetic compatibility (EMC) of the SPECTOR
control
. Therefore, take special care during
connection.
■
Make sure wiring is in line, not in a star!
■
Route the data cable separately from power lines.
■
Use a central earth to prevent differences in potential between system parts.
■
Connect the bus cable shields such as to ensure electrical continuity, and connect to
the central earthing point (CEP).
■
If two or more system components are connected in a CAN bus network, install a
120 Ω terminating resistor (CAN LOW/CAN HIGH module) to the first and last units.
