Page 9: Safety Instructions
Safety instructions Risk of death resulting from failure to observe the safety instructions and residual risks If you fail to heed and comply with the safety instructions and residual risks in the associated converter documentation, accidents can occur. This can result in severe injury or death. •... - Page 10 Safety instructions with a very low probability, the machine builder (OEM) must carefully check as to whether additional measures are required. Incorrect handling when the motor suddenly moves can result in death, serious injury or substantial material damage. • Adopt suitable protective measures to ensure that personnel is not endangered by the motor jerking into motion from standstill.

Page 11: Description
Description When the "Two-channel firing pulse inhibit" function is selected, the following points apply: • The optical pulse transmission to the PSA to control the firing pulses on the thyristor gating module is switched off. • The Motor Module and the motor are not electrically isolated. Note Active loads Using the function, drive systems with active loads cannot be protected against restarting... - Page 12 PSA ground potential is at the ground potential of the converter housing. The components of the two-channel firing pulse inhibit are supplied with the same voltage. ③ Siemens 3SK1122-2CB4x safety relay (included in the scope of delivery of the option) Terminal Connection...
