2. Installation and connection
●Procedure for connection to BU3002SW output terminal block
Caution
When in use, make sure the output terminal block cover is attached. Do not turn ON the power switch when it is detached.
●Voltage is applied to the output terminal block when the power switch is ON, which can result in electric shock.
When connecting a device to the output terminal block, make sure to include an emergency stop switch (ESD) between them.
●In the event of an accident, the power supply to the device can be stopped by pressing the emergency stop switch.
●A disconnect switch shall be provided by others for ac output terminal block circuit.
●To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent protection for 20 amperes rating in accordance with the National Electric Code, ANSI/ NFPA 70.
