Wiring

AMAX-5000 I/O modules leverage detachable clamp type terminal blocks. Compar-
ing with traditional screw type terminal blocks, clamp type terminal blocks can save
wiring time and provide better reliability for shock and vibration. Follow the proce-
dures below for wiring your AMAX-5000 I/O module.
1. Use the screw driver to press the left notch on the terminal.
2. Insert the wire into the terminal.
Note! Please use # 14 AWG ~ 28 AWG wire for terminal block.

Cable Length

According to the structured cabling model defined in the ISO/IEC 11801 specification,
cables employed in the connection between two end devices can be distinguished
into (as shown in Figure 2.4):
1. Permanent link, which is the main cable span between two end devices,
installed either within or outside the cabinet.
2. Patch cords, which are typically short cable sections, used within a cabinet
between end devices and intermediate connection points (like bulkhead feed-
through connectors)
In terms of planning the EtherCAT networks with use of 100BASE-TX link (copper
wire), the following rules can be considered:
1. The total length of the communication channel (including permanent link and all
patch cords) should not exceed 100 m.
2. The total length of the patch cords at each end should not exceed 5m, and the
length of the permanent link should be reduced accordingly to meet the maxi-
mum channel length of 100m as described previously.
3. The maximum number of connections in the channel should be 6 including con-
nectors at each end.
4. In any case, the channel length should be kept as short as possible.
