NISSEI CORPORATION E6581815B-322.2 Standard connectionsWarningProhibited Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3).Connecting input power to the output could destroy the inverter or cause a fire. Do not insert a resistor between DC terminals (between PA/+ and PC/-, or between PO and PC/-).It could cause a fire. First shut off input power and wait at least 15 minutes before touching wires on equipment (MCCB) thatis connected to inverter power side.Touching the wires before that time could result in electric shock. Do not shut down the external power supply on ahead when VI terminal is used as logic input terminalby external power supply (f127=0).It could result in malfunction as VI terminal is ON status.Mandatoryaction Confirm to logic setting of slide switch SW1 (LOGIC) and parameter f127 (sink/source switching)when F, R, S1, S2 terminals and VI terminal are used as logic input terminal.If it is not set, it could result in malfunction.Be Grounded Ground must be connected securely.If the ground is not securely connected, it could lead to electric shock or fire when a malfunction orcurrent leak occurs.
