Installation guide and mechanical dimensions
5.1 Installation environment requirements
The eTOP series 300 operation panel is not suitable for continuous exposure to direct sunlight, which may accelerate the aging process of the front panel film. Similarly, equipment should not be installed in locations that come into contact with corrosive compounds. Before installation, the resistance of the front panel film to specific compounds should be checked.
The keyboard or touch screen of the operation panel must not be operated with any tools (such as screwdrivers, etc.) to avoid damage.

5.3 Installation of rectangular sealing gasket
The sealing gasket should be installed at the rear of the frame. During installation, it is necessary to ensure that the edge of the opening is flat, and tighten each fixing screw until the plastic frame corner contacts the panel. The opening size must comply with the provisions of this manual to ensure the effectiveness of the IP66 protection level.
Detailed description of connection interface
6.1 Interface Layout
The eTOP series 300 operation panel provides a complete connection interface, including:
power connector
Auxiliary Port (AUX Port)
PLC port
PC/printer port
Ethernet port
USB port
6.2 Serial Port (PLC Port)
Serial ports are used for communication with PLCs or other types of controllers. The PLC port connector supports multiple electrical standards: RS-232, RS-422, RS-485. This port is software programmable, and users need to select the appropriate interface in the programming software.
RS-232 pin definition:
Pin 1: GND
Pin 2: Empty
Pin 3: TX
Pin 4: RX
Pin 5: Empty
Pin 6:+5V output
Pin 7: CTS
Pin 8: RTS
Pin 9: Empty
Definition of RS-422/RS-485 pins:
Pin 1: GND
Pin 2: Empty
Pin 3: CHA-
Pin 4: CHB-
Pin 5: Empty
Pin 6:+5V output
Pin 7: CHB+
Pin 8: CHA+
Pin 9: Empty
Communication cables must be selected based on the type of equipment they are connected to.
6.3 Ethernet ports
The Ethernet port uses standard RJ45 connectors, with pin definitions as follows:
Pin 1: TX OUT+
Pin 2: TX OUT-
Pin 3: RX OUT+
Pin 4: Empty
Pin 5: Empty
Pin 6: RX OUT-
Pin 7: Empty
Pin 8: Empty
6.4 Auxiliary Port (AUX Port)
The auxiliary port is a communication port designed specifically for industrial network communication, using a 9-pin D-sub connector. The functionality of the AUX port depends on the optional communication module of the insertion unit. When installing the module, press all four corners at the same time. Do not plug or unplug the module when the operation panel is powered on.

Power supply, grounding, and shielding technology
7.1 Power Requirements
The power terminal is located at the designated position of the equipment. Users must ensure that the power supply has sufficient capacity to support device operation. All electronic devices must be properly grounded in the control system, as grounding helps to limit the impact of electromagnetic interference on the control system.
7.2 Grounding specifications
The equipment must always be grounded. The grounding connection should be made using screws or Faston terminals near the power terminal, and the grounding connection point should be labeled. At the same time, terminal 3 on the power supply terminal should also be grounded.
The power circuit can be floating or grounded. In the grounding scheme, the common terminal of the power supply should be grounded (as shown in the dashed line connection in the figure). When using a floating ground power supply solution, please note that the common terminal of the power supply is grounded through a 1M Ω resistor and a 4.7nF capacitor connected in parallel inside the panel. The power supply must have dual or reinforced insulation.
7.3 Recommended wiring method
The recommended wiring method for the power supply is shown in the diagram. Grounding must be carried out in accordance with applicable regulations to ensure system safety and EMC performance.
