• Electrical equipment must be installed, operated, serviced, and maintained
only by qualified personnel.
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices.
• Disconnection devices for AC and DC must be provided by others, be readily
accessible, and the function of the disconnect device marked for its function.
• Turn off all power before working on or inside the equipment.
• Before working on the UPS system, check for hazardous voltage between all
terminals including the protective earth.
• The UPS contains an internal energy source. Hazardous voltage can be
present even when disconnected from the mains supply. Before installing or
servicing the UPS system, ensure that the units are OFF and that mains and
batteries are disconnected. Wait five minutes before opening the UPS to
allow the capacitors to discharge.
Failure to follow these instructions will result in death or serious injury.
When the UPS input is connected through external isolators that, when opened,
isolate the neutral or when the automatic back feed isolation is provided external to
the equipment or is connected to an IT power distribution system, a label must be
fitted at the UPS input terminals, and on all primary power isolators installed
remotely from the UPS area and on external access points between such isolators
and the UPS, by the user, displaying the following text (or equivalent in a language
which is acceptable in the country in which the UPS system is installed):
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
