Procedure for connection to BU3002SWG output terminal block
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 an emer-
gency stop switch (ESD) overcurrent protection for
20 amperes rating in accordance with the National
Electric Code, ANSI/NFPA 70, when using the UPS
as a device conforming to CE standard.
