Applicable to RSBS2332A2V.2C24HP ATTENTION: The RSBS soft starter is NOT to be used as a safety device. The RSBS, on its own, cannot guarantee any safety and therefore other components need to be used to ensure that the system operates safely. Note: Power up is defined as the moment when L/L1 and N/L2 are applied to the RSBS. Specifications are subject to change without notice (12.12.2013) 1RSBS23..A2V.2C24..
