Preface
Thank you for purchasing the H3U series programmable logic 
controller (PLC). It is a third-generation high-performance PLC 
development by Inovance based on the new-generation industrial CPU 
and FPGA hardware architecture and self-owned industrial embedded 
software design.

◆
The above EMC directives are complied with only when the 
EMC electric installation requirements are strictly observed.
 
◆
Machines and devices used in combination with this PLC 
must also be CE certied and marked. The integrator who 
integrates the PLC with the CE mark into other devices has 
the responsibility of ensuring compliance with CE standards 
and verifying that conditions meet European standards.
 
◆
The installer of the PLC is responsible for complying with 
all relevant regulations for wiring, circuit fuse protection, 
earthing, accident prevention and electromagnetic (EMC 
regulations). In particular fault discrimination for preventing 
re risk and solid earthing practices must be adhered to for 
electrical safety (also for good EMC practice).
