1.1 Safety notices

Symbol/sign Meaning
DANGER
This manual provides information for the safe operation of the HiPerGuard MV UPS. It does NOT
provide installation, commissioning or service information. For such information, refer to the ap-
propriate manual.
CAUTION – Trained operators
All operations on the HiPerGuard MV UPS must only be carried out by a trained operator familiar
with the contents of this manual. Hazardous conditions could arise from incorrect adjustment.
DANGER – Hazardous voltages
An Operator must not open doors or panels marked as containing hazardous voltages. Many parts in
this product, including printed circuit boards operate at lethal high voltages. Stored energy compo-
nents such as batteries and capacitors can hold this voltage even after the opening of isolation
switches. DO NOT TOUCH components or connections that may have voltage present.
DANGER – High voltages
Lethal high voltages are present inside the MVM and Medium Voltage Switchgear enclosures under
normal operation or fault conditions. Do not remove any panels or guards. This may only be done by
trained technical personnel after following the stipulated isolation, grounding, and lockout proce-
dures. DO NOT TOUCH components or connections that have voltage present.
DANGER – Stored charge
Stored charge is present after the device is switched off. When the MV UPS is powered down, lethal
voltages will remain in the energy storage elements and the complete HiPerGuard MV UPS should be
considered live. To remove this hazard, energy storage will need to be isolated and locked off, and
filter capacitors discharged. This may only be done by trained technical personnel while following
the stipulated isolation, grounding, and lockout procedures.
DANGER – Protective covers
Normal operation of this product requires all protective covers to be in place and all doors secured
closed.
DANGER – Personal Protective Equipment
Ensure safety glasses and other appropriate PPE are worn while working if any part of the unit could
be energized. Observe site requirements for PPE while operating this equipment.
