2.1 Installation Requirements
■ Installation precautions
Before installation, make sure the HMI is powered off.
● Prevent the enclosure or terminals or connectors of the HMI from dropping or
suffering from impact or shock.
● Do not disassemble the HMI to avoid damage to it.
● Do not fasten with excessive torque to avoid damage to the HMI.
● After installation and commissioning, remove the dustproof label on the upper
side of the HMI to keep the vents open to ensure reliable operation at high
temperatures.
■ Installation environment requirements
The HMI is designed to operate in a temperature range between ‑10°C to 55°C (0°C to
50°C for IT7070S), exceeding of which may cause damage to the HMI components,
malfunction, or function deterioration. For use in special environments, contact
Inovance.
● Do not install the HMI in environments suffering from strong mechanical vibration.
● Install the HMI in a cabinet with a depth of over 100 mm and keep a space of at
least 25 mm around the equipment.
● Install the HMI away from cables and devices that generate strong interference,
such as AC power supply cables, PLC output modules, AC drives, and relays. Use
shielded cables for I/O cables and ground the shielded cable properly.
● The front panel of the HMI meets IP65. When the HMI is installed in a IP65‑rated
cabinet, the cabinet must retain its IP rating, which means liquid sprayed on the
cabinet cannot get into it.
