In the case of fire, leave the building or the equipment room immediately, and turn on the
fire alarm bell or make an emergency call. Never enter the building on fire in any case.
If the cabinet provides an ESD jack, wear an ESD wrist strap and insert the ground
terminal of the ESD wrist strap into the jack.
Ensure all switches are turned to OFF during device installation.
Power on the UPS only after authorized engineers arrive at the site.
If a C2 UPS is used in residential areas, additional measures must be taken to prevent
radio frequency interferences.
If the UPS is used for life-supporting medical apparatus and facilities such as lifts where
adequate care has to be taken to ensure personal safety, discuss with the manufacturer in
advance about the applicability, settings, management, and maintenance of the UPS,
which require special considerations during design.
Device Safety
Before operation, ensure that the device is firmly anchored to the floor or other solid
objects, such as a wall or an installation rack.
Ensure ventilation vents are unblocked while the system is operating.
Before powering on the device, ensure that all the screws inside it are securely tightened
and will not fall off during operation.
After the installation, remove packing materials from the equipment area.
Replace danger signs that have worn out or are unreadable.
A UPS can be used to serve resistive-capacitive loads, resistive loads, and
micro-inductive loads. It is recommended that a UPS not be used for pure capacitive
loads, pure inductive loads, and half-wave rectification loads. It does not apply to energy
feedback loads.
Do not alter the UPS internal structure or installation procedure unless consent from the
manufacturer is given.
Never use water to clean electrical components inside or outside the UPS.
Do not drill holes into a cabinet.
1.2 Electrical Safety
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact with high voltage power sources may result in fatal injury.
Non-standard or incorrect high voltage operations may result in fire and electric shocks.
The personnel who install the AC facility must be qualified to perform high voltage and
AC operations.
When selecting, connecting, and routing power cables, ensure compliance with local
laws and regulations.
