PrODUCT DESCrIPTION 2 Product Description The safety manual completes the installation manual of the COMBIVERT with the safety module of type 1. It contains safety-related supplements and regulations for the operation of devices in safety applications. The basic standards as well as application and country-specific standards must be observed furthermore. -
Page 16: Safety Functions
SAFETY FUNCTIONS 3 Safety Functions 3.1 General instructions Danger Electric Shock The COMBIVERT is operated with dangerous voltages which can cause death or serious injury. The COMBIVERT can be adjusted by way that in regenerative operation energy is regenerated into the mains also during mains power failure. Therefore a dangerous high tension can exist in the unit after switching off the supply system. -
Page 17: Safe Torque Off (Safe Torque Off - Sto)
SAFETY FUNCTIONS With electronic protection devices there are safety functions integrated in the drive control in order to minimize or eliminate danger by malfunctions in machines. The integrated safety functions replace the complex installation of external safety components. The safety functions can be requested or released by an error. -

SAFETY FUNCTIONS Attention Power-off braking Use brakes which are closed at power-off state. A classification of the entire brake system inclusive mechanical brake to SIL 3 and PL e must be evaluated depending on the used brake. Brakes are considered as components with relatively high error probability. A test interval for the brake is set depending on the manufacturer specified error probability of the used brake and depending on the application. -

Page 26: Function Description Sto
FUNCTIONAL DESCrIPTIONS 6.2 Function description STO The safety-related disconnection according to STO is reached by a two-cannel opto-coupler block- age. The supply of the opto-couplers, which are responsible for the commutation of the connected drive occurs via transformation coupling of the input voltage. This ensures at input voltage loss that no supply of the opto-couplers is possible. -
