• Procedure for connection to power supply output receptacle (IEC60320 C13)
Connect it directly.
● Procedure for connection to BU1002SWG 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
15 amperes rating in accordance with the National
Electric Code, ANSI/NFPA 70, when using the UPS
as a device conforming to, CE standard.
(1) Remove the terminal block cover on the lower right side of the unit's
rear panel.
(2) Connect the units that need to be backed up. Two types of connections
can be made.
1) To turn ON/OFF at the same timing as that of output receptacle B:
L1B terminal: Connect the line
L2B terminal: Connect the neutral line
2) To turn ON/OFF at the same timing as that of output receptacle C:
L1C terminal: Connect the line
L2C terminal: Connect the neutral line
Run the wires to be connected through the hole in the included terminal block cover (with cable
clamp and cable guard tube). (See Figure 1.)
If you have trouble running the wire through the hole, loosen the cable clamp dial by turning it
counter-clockwise.
Connect the ground wire to the G terminal.
Use a flat head screwdriver to loosen the terminal block screws, insert the wire, and then retighten
the screws. (See Figure 2.) Refer to Table 1 for wire sizes.
