Higher-level systems
When an original equipment manufacturer (OEM) or a system integrator adds equipment such as
cutting tables, motor drives, motion controllers, or robots to a Hypertherm waterjet cutting system,
the system is considered a higher-level system. A higher-level system with dangerous moving parts
can constitute industrial machinery or robotic equipment, in which case the OEM, system integrator,
or end-use customer can be subject to more regulations and standards than those applicable to the
waterjet cutting system manufactured by Hypertherm.
It is the responsibility of the end-use customer and the OEM or system integrator to do a risk
assessment for the higher-level system and to provide protection against dangerous moving parts.
Unless the higher-level system is certified when the OEM or system integrator incorporates
Hypertherm products into it, the installation can be subject to approval by local authorities. Get
advice from legal counsel and local regulatory experts if you are not sure about compliance.
External cables connecting parts of the higher-level system must be made for exposure to
contamination and movement as necessary for the end-use installation site. When the external
interconnecting cables are subject to exposure to oil, dust, water, or other contamination, hard
usage ratings could be necessary.
When external interconnecting cables are subject to continuous movement, constant flexing ratings
can be necessary. It is the responsibility of the OEM, system integrator, or end-use customer to
make sure that external connecting cables are correct for the application and obey all national, state,
and local regulations.
