Connect the load devices.
①
Attach the supplied cable clamps to the input
power plug of the load device to be connected.
②
Check that the input breaker
MAIN MCCB
is set to “OFF”.
③
Connect the input power plugs of the load devices to the output terminals.

This completes the load devices connection.
Connect as shown below, according to the type of grounding in the area where you are installing the UPS.
Areas which do not have single-line grounding:
If the load device input plug is a NEMA-type plug,
connect the W (N) terminal of the load device input plug to the N terminal of the UPS. (See the above figure.)
Areas which have single-line grounding:
If the load devices are a single-wire grounded connection, always
connect the ground phase to the N terminal (phase) side. (See the above figure.)
Never connect the following types of load devices to the UPS.
Load devices
Details
Copy machines, Laser printers,
Plain paper fax machines,
Overhead projectors, Hair-dryer, Cleaner
and so on.
Since such devices are subject to high transient current
surges, the UPS will detect the excess current and
backup will not be possible when there is a power
outage. There is also the risk of the UPS malfunctioning.
Medical equipment, control equipment for
elevators and the like, computer systems
of public importance.
Special considerations such as system redundancy,
installation of emergency power generation facilities,
need to be given to operation, maintenance, and
management.
Attach the cable clamp to
the input plug of the load.
②
Breaker is “OFF”.
③
Insert the cable clamp into the hole, and
then connect the input power cable of the
load device.
Do not strain the cable clamp too tightly.
