Compliance

Product Integration & Compliance

OEM INTEGRATION RESPONSIBILITY

This product is a component or configurable module intended for integration into an OEM, commercial, industrial or research system.

The customer is responsible for final product selection, system-level risk assessment, safety functions, mechanical and electrical integration, validation, certification and regulatory compliance.

Published ratings apply only under the stated conditions. Confirm the operating point, interfaces, control compatibility, thermal conditions, duty cycle and required documentation before final selection.

This product is not approved for a safety-critical or restricted application unless expressly authorized in writing.

MOTOR AND ACTUATOR INTEGRATION

Confirm continuous and peak operating points, load inertia, acceleration, shock, radial and axial loading, mounting accuracy, cooling, drive compatibility, encoder interface, braking behavior and fault response.

A standard holding brake is not represented as a safety brake unless the Exact SKU is expressly identified and documented as safety-rated.

Mechanical stops, guards, interlocks, emergency functions and system-level functional safety remain the responsibility of the machine manufacturer and system integrator.
