1.2 Electrical Safety

High Voltage
Issue 10 (2015-09-15)
To avoid electric shocks, do not connect safety extra-low voltage (SELV) circuits to
telecommunication network voltage (TNV) circuits.
Before performing operations on a device, wear electrostatic discharge (ESD) clothes,
ESD gloves, and an ESD wrist strap. Do not wear jewelry or watches during the
operation to avoid electric shocks or burns.
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.
Keep all switches OFF during device installation.
Power on the UPS only after authorized engineers arrive at the site.
If you use a C2 UPS in residential areas, take installation restriction or additional
measures to prevent radio frequency interferences.
If you use the UPS for life-supporting medical apparatus and facilities such as lifts where
adequate care has to be taken to ensure personal security, discuss with the manufacturer
in advance about the applicability, settings, management, and maintenance of the UPS,
which require special considerations during design.
Before operation, ensure that the device is firmly anchored to the floor or other solid
objects, such as a wall or an installation rack.
Do not block ventilation vents while the system is operating.
Before powering on the device, ensure that it is securely screwed and will not fall over
during operation.
After the installation, remove packing materials from the equipment area.
Replace warning labels that have worn out.
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 inductive
loads, and half-wave rectification loads. It does not apply to the regeneration load.
Without prior consent from the manufacturer, do not alter the UPS internal structure or
installation procedure.
Never use water to clean electrical components in the interior and exterior of the UPS.
