The Siemens 6SN1145-1BA01-0BA1 is a Simodrive E/R infeed module with an internal cooling system. The Simodrive 611 system can be connected directly to TN 3 phase line supplies with a voltage of 380, 400, 415, or 480 Vac. Matching transformers tailored for the system are available to connect the entire system to other supply types. If you are using upstream devices to provide protection against hazardous leaking currents or fire protection, these must be AC/DC sensitive. If you are using other residual current protective devices, a transformer with separate windings must be connected upstream in order to decouple. Because the modules in the system, like the 6SN1145-1BA01-0BA1, are under such high voltage, caution must be taken when handling the units and their cables. Even after power has been disconnected, dangerous levels of voltage can still reside in modules. In capacitor modules, this can be as long as 30 minutes. Be sure before switching off devices that the pulse inhibit on the 6SN1145-1BA01-0BA1 and other feedback modules are disabled. Otherwise the module can become damage and damage other equipment in the control cabinet.
Many components in the Simodrive system like the 6SN1145-1BA01-0BA1 are electrostatic discharge sensitive devices. These are components which can be destroyed by an electrostatic discharge, such as integrated circuits or boards. It is important when handling these devices that personnel, workstations, and packaging remains well grounded. Generally these modules should not be touched unless work is being performed on them. Modules should also not be brought close to data terminals, television sets, or monitors. Make sure that if you are performing measuring work that the measuring unit is grounded, or if you are using floating measuring equipment, that the probe is briefly discharged before making measurements. Understand that when you boot the system, that there is an increased risk due to a critical operating state, especially for units like the 6SN1145-1BA01-0BA1. Personnel should remain as far from the hazardous area as possible.
