3.3 Installation of the cable
3.3.1 Installation of XGL-PMEA/PMEB/PMEC
[Figure 3.3.1] The method of Pnet cable installation
1) Installation length of Pnet cable depends on the communication speed. (Refer to [Table] 2.4.2)
1) How to install Pnet cable
(1) Use Profibus-DP cable.
(2) When slipping the coat of the cable, be careful not to let the shielded line escaped from PCB of
the connector.
(3) The number of stations to be installed shall be within 32 including master and repeater for 1
segment.
(4) The shielded line of the cable shall be in contact with the shielded area of the connector.
(5) The cable is generally recommended to be installed at the end of the slave, diverged from the
master.
(6) If the cable is used at the object car, use the extended line.
(7) Communication cable shall be installed at least 10cm away from the power supply cable.
(8) Check the cable connected with the connector if tightened well with terminal block.
(9) After the cable connected, measure the line resistance value on the master by means of digital
multi-meter. (If terminal resistance at the both ends of the cable is On, it will be generally 110Ω +
line resistance value + connector resistance value)
