Data for operation and environment

Beckhoff products are designed for operation under certain environmental conditions, which vary according to the product. The following specifications must be observed for operation and environment in order to achieve the optimum service life of the products.

	Operate the braking resistor only under the specified environmental conditions Operate the braking resistor only in accordance with the specifications for operation and the environment listed in this chapter. This ensures a long service life and proper operation. The lifetime of the braking resistor may be shortened at temperatures above +40 °C and with encapsulated installation.
