Safety Precautions Installation and Wiring 7 WARNING Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury due to an electric shock. Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious injury due to an electric shock. Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire. CAUTION Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring. Install a stop motion device to ensure safety. Not doing so might result in a minor injury.
Be sure to use a specified type of Braking Resistor/Regenerative Braking Unit. In case of a Braking Resistor, install a thermal relay that monitors the temperature of the Resistor. Not doing so might result in a moderate burn due to the heat generated in the Braking Resistor/ Regenerative Braking Unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is detected in the Braking Resistor/Regenerative Braking Unit. Do not connect Resistors to the DC terminals (P, N) directly. Doing so might result in a small-scale fire, heat generation or damage to the unit.
