2-3-3 Connecting a device to the AC output (terminal block)
(BU5002R, BU3002R only)
Connect a device required for backup to the “AC output” terminal block of the UPS.
Warning
When fixing the wiring to the terminal block, use the prescribed
round terminal, and after crimping with the prescribed amount
of stripping, tighten with the prescribed torque.
⚫
There is a risk of smoke generation and ignition due to defective contact if
the prescribed round terminal or the amount of stripping are not used.
⚫
There is a risk of smoke generation and ignition if a bare wire is used or a
screw is loose.
Caution
When using this unit, make sure to attach the output terminal
block cover. In addition, do not turn on the
“Power” switch when
the cover is removed.
⚫
If the “Power” switch is turned on, voltage is applied to the output terminal
block, which may cause electric shock.
⚫
When replacing a cable, make sure the to fix the cable with a clamp.
Notes
When connecting a device using an output terminal block, be sure to insert
an emergency stop switch (ESD) between the output terminal block and the
connected device.
⚫
In case of an unforeseen fault, power supply to the connected device can be stopped by
tripping the emergency stop switch.
⚫
To prevent a fire, connect an emergency stop switch (ESD) rated 30 A or more to the
BU5002R, and 20 A or more to the BU3002R/BU3002RH. (When this unit is used as a
conforming product of UL standards, follow the National Electrical Code, and
ANSI/NFPA 70)
⚫
Arrange the emergency stop switch in a location that is easy to operate.
