4.2 Connecting EtherCAT Ports


There is a strict network topology requirement for the EtherCAT network. The network must follow the
rule that the input port of the next ASRTU-EC16AP must be connected to the output port of the current
ASRTU-EC16AP.

Using Delta cables for EtherCAT communication is recommended. For specifications of Delta cables,
refer to Appendix A.

4.3 Wiring

4.3.1 Power Input

The power input of ASRTU-EC16AP is 24V DC. Please notice the following points during use.

Connect the supply power to the two terminals, 24V and 0V and the grounding terminal to the earth.
Be cautious that the ASRTU-EC16AP device may be damaged if the positive and negative polarities
of the supply power are connected reversely.

Please be sure to use certified power supply with SELV output or certified power supply providing
double insulation evaluated by UL60950, or UL61010-1 and UL61010-2-201 standards

The diameter of the power wire must be between 22 and 18 AWG and the rated temperature should
be greater than 70°C. The power terminal block plug wiring torque is 4.5 in-lbs.

The cables of the AC power 110V, 220V and DC power 24V must be twisted and connected to the
module as short as possible in length.

Do NOT combine the AC 110V, 220V, and DC 24V cables with the main circuit and I/O signal cables
together and please keep them away from each other. If the space permits, it's recommended to
separate these lines by more than 100mm.
