3 Installation Instructions
Allow adequate clearance around the connection box for ventilation and cable routing. Also, consider heat generated by nearby devices and ensure the ambient temperature around the connection box remains within 0 ~ 55°C.
Minimum required clearances (from enclosure):
- Top: 10 mm
- Sides: 10 mm
- Bottom: 120 mm
Screw Installation with Protective Components
Components:
- 1 Rubber washer
- 2 Screw
- 3 Metal washer
- 4 Nut
Installation Steps
- Confirm that the mounting hole diameter is 4.6 mm, and attach the rubber washers to the inner surface of the control box.
- Insert the screws from the outside through the connection box and control box wall.
- On the inside of the control box, place the metal washers onto the screws, then attach the nuts and tighten securely.
Disassembly and Installation of the Standard Connection Box Front Cover
Components:
- Front Cover
- Screws
- Cable Glands
Installation Steps
- Loosen the screws and remove the front cover.
- Route and connect the cable.
- Reinstall the front cover and tighten the screws.
Torque Specifications
Mounting screws: 2.1~3.4 lbf-in (ensure waterproofing and prevent damage to the enclosure's screw holes)
Cable glands (for Ø 4~8 mm cable): 33~48 lbf-in
Connecting the Handheld HMI to the Standard Connection Box
- Align the red dot on the handheld HMI's cable connector with the red dot on the connection box's cable connector.
- Push the cable connector in firmly until you hear it snap into place indicating it's fully engaged.
Removing the Standard Connection Box
- Use your thumb and index finger to pull the cable connector's outer ring all the way back, and pull the connector straight out to detach.

CAUTION
Power
NOTE: Make sure that all local and national electrical standards are met when installing the unit. Contact your local authorities to determine which codes apply. Use power output that meets SELV (Safety Extra-Low Voltage) requirements. The unit can be powered by DC power only, voltage range: 24±20%, compatible with most controller DC systems. The power conditioning circuitry inside the unit is accomplished by a switching power supply. The peak starting current can be as high as 2A.
Fusing Requirements
If the handheld HMI display does not turn on within 5 seconds of power-up, remove power. The handheld HMI features a resettable fuse to protect against overcurrent faults in the DC circuit; the fuse will reset automatically after a period of time. Check wiring for proper connections and try to power up again.
High Voltage
The handheld HMI's resettable fuse will prevent damage under overcurrent conditions; however, protection is not guaranteed. DC voltage sources must be properly isolated from main AC power and similar hazards.
Emergency Stop
A Hard-wired EMERGENCY STOP should be fitted in any system using an HMI to comply with ICS Safety Recommendations.
Supply Voltage Condition
Do not power the unit and inductive DC loads, or input circuitry to the controller, with the same power supply. Note: The 24 VDC output from some controllers may not have enough current to power the unit.
Wire Routing
- Power wire length should be minimized (Max: 500m shielded, 300m unshielded).
- Please use twisted pair cables for power wire and signal wire and conform to the impedance matching.
- If wiring is to be exposed to lightning or surges, use appropriate surge suppression devices.
- Keep AC, high energy, and rapidly switching DC power wiring separated from signal wires.
- Add a resistor and capacitor in the parallel connection between the ungrounded DC power supply and the frame ground. This provides a path for static and high frequency dissipation. Typical values to use are 1M Ohm and 4700pF.
DANGER
Hardware Considerations
The system designer should be aware that devices in Controller systems could fail and thereby create an unsafe condition. Furthermore, electrical interference in an operator interface can lead to equipment start-up, which could result in property damage and/or physical injury to the operator. If you use any programmable control systems that require an operator, be aware that this potential safety hazard exists and take appropriate precautions. Although the specific design steps depend on your particular application, the following precautions generally apply to installation of solid-state programmable control devices, and conform to the guidelines for installation of Controllers recommended in NEMA ICS 3-304 Control Standards.
Programming Considerations
To conform to ICS Safety Recommendations, checks should be placed in the controller to ensure that all writable registers that control critical parts of plant or machinery have limit checks built into the program, with an out-of-limit safe shut down procedure to ensure safety of personnel.
