Pointek CLS 300 digital unit on a PROFIBUS
network

Specifications

Please see page 10.
Wiring: connection to a PROFIBUS PA network
WARNING: The requirements listed under WARNINGS on page 10 must be fulfilled.
Notes:
• Lay PA cable separately from power cable with voltages greater than 60 V AC.
• If possible, avoid locating Pointek CLS 300 near large electrical equipment.
• Connect the cable shield to earth (for example, to the housing by means of a metallic
screwed gland).
PROFIBUS PA connection to screw terminals
Connect the PROFIBUS cable to the screw terminals, following the instructions on page 11.
.
PROFIBUS PA connection via M12 plug
If an M12 plug is installed on the Pointek CLS 300
enclosure, a female M12 receptacle is required
on the end of the cable, to complete the bus
connection to PROFIBUS PA.
The usual PROFIBUS PA recommendation is to
ground the shield on both the device side and
the cable side. In some cases (for example, on
cathodically protected tanks), it may be
preferable to ground one side only, to avoid
ground loops.
Follow the instructions
accompanying the
female receptacle.
