Delta CMM-EC02 - Grounding

 Grounding

You must ground the communication card when wiring CMM-EC02. The ground terminal is
included in the communication card package, as shown in Fig.2-7.

 Recommended wire size for grounding:
 Wire gauge 16–20 AWG
 Category 5 (Cat5 / Cat5e), Class D or above cable according to ISO/IEC 24702
(ISO/IEC 11801-3) and EIA/TIA 568-A-5
 Maximum cable length 100 m
 Installation of the ground terminal:
 When grounding, it is recommended to use grounding specifically for communication
or clean grounding
 The PE terminal for CMM-EC02 includes PE1 and PE2. It is recommended to ground
PE1 and PE2 at the same time and adjust according to actual situation.
 PE1 (communication reference ground): connects to communication reference ground
internally. Connecting PE1 to the ground reduces noise from those in application.
 PE2 (RJ45 shielded layer): connects to RJ45 shielded layer internally. Connecting
PE2 to the ground reduces noise from periphery.
 Grounding example: If you cannot use grounding specifically for communication, you
can ground the drive’s PE to the equipment. The B end of the grounding wire
connects to the ground terminal block of the communication card, as the circle shows
in Fig.2-8. The A end of the grounding wire connects to the drive’s PE, as the circles
show in Fig.2-9, Fig.2-10, Fig.2-11 and Fig.2-12 by different frames for
MS300/MH300.
