Models with separate bypass line, a galvanic isolation
transformer has to be installed in any of the two lines that
supply the UPS (rectifier input or static bypass), to avoid the direct
union of the neutral of both lines through the internal wiring of
the equipment.
This is applicable when the two lines are supplied from different
mains, i.e.:
Two different electrical companies.
An electrical company and genset, ...
• All the equipments have an auxiliary terminal strip to install an
external emergency power off button (EPo).
The type of circuit is selectable through the lCD panel of the
equipment. The contact is preset from factory as normally open,
so the button must be switched to close the circuit and the
voltage to the loads is broken. To establish the power supply to
the loads again, the EPo button must be deactivated.
EPo doesn't affect to the power supply of the equipment, it only
breaks the power supply to the loads as a safety measure.
•
when supplying input voltage to a UPS with fitted in or
separate static bypass, although the inverter is still turned
«off» (deactivated) it doesn't mean that at the output there will
not be voltage.
So, to do it, the input and static bypass switches will have to be
turned «off».
Put warnings of danger and/or emergency switches if the safety
Standards require it in your particular installation.
•
it is possible that the UPS supplies output voltage through
the manual bypass to those equipments that incorporate
it either standard or optional, so it will have to be considered as
regards to safety. if it were necessary to break the output supply of
the equipment in this situation, deactivate the outgoing distribu-
tion protection or in case of lack of it the general protection of the
distribution panel that feeds the UPS.
• All power supply electrical cables have to be fixed to the equip-
ments and loads, interfaces, etc..., to unmovable parts and in the
way to avoid treads, trips on them or fortuitous pulls.
• Phase equipments in the foreseen terminal for that purpose.
• CHASSiS or RACK mounted equipments are destined to be installed
in a predetermined set to be done by professionals.
The installation has to be designed and executed by quali-
fied personnel, who will be the responsible to apply the
safety and EMC regulations and standards that controls the
particular installations where the product is destined.
The equipments assembled in CHASSiS do not have enclo-
sure protection, even the power blocks are unprotected.
Some RACK mounted equipments do not have the power
blocks protected.
• never manipulate the equipment with wet hands.
1.2.3.2. To keep in mind
•
Do not try to dismantle or change any part of the equip-
ment, if this action is not contemplated in this document.
Manipulation inside the UPS due to any modification, reparation
or any other cause, can make an electrical discharge of high
voltage and it is restricted to qualified staff only. Do not open the
equipment.
A part from the implicit stated risks, any action that make the
modification, internal or external of the equipment or just only
the simple intervention inside of itself, which is not stated in this
document, it can expire the warranty.
• if it is observed that the UPS exhausts smoke or toxic gas, shut-
down it immediately and disconnect it from the power supply.
This kind of fault can cause fire or electrical discharge. Contact our
KESS Support-Team.
• in case of an accidental equipment dropping or if the enclosure is
damaged, do not start it up under any concept. This kind of fault
can cause fire or electrical discharge. Contact our KESS Support-
Team.
• Do not cut, manipulate the electrical cables, do not put heavy
objects over them too. Any of these actions could cause a short-
circuit and make a fire or electrical discharge.
Check that the electrical cables of connection, plugs and outlets
are in good conditions.
• when moving an equipment from a cold place to a warm en-
vironment and vice versa, it can cause condensation (small
water drops) in the external and internal surfaces. before
installing a moved equipment from another place or even
packaged, the equipment will be left for a minimum time
of two hours in the new location before making any action,
with the purpose of adapting it to the new environmental
conditions and avoid the possible condensations.
The UPS has to be completely dry before starting any installation
task.
• Do not store, install or expose the equipment in corrosive, wets,
dusty inflammable or explosive environments and never out-
doors.
• Avoid to locate, install or store the equipment in a place with
direct sunlight or high temperatures. batteries could be dam-
aged.
in the exceptional case and long exposition to intense heat,
batteries can cause filtrations, overheating or explosions,
which can cause fires, burn or other injuries. High tempera-
tures can also make deformation in the enclosure.
• The location will be spacious, airy, away from heat sources and
easy access.
• Do not obstruct the cooling grids by entering objects through
themselves or other orifices.
• in equipments of low power rate (up to 3kVA), leave as minimum
space of 25 cm in the equipment peripheral and 50 cm for higher
power rates equipments.
• Also in the UPS with power blocks, it is recommended to leave
another additional 50 cm for an eventual intervention of the
KESS Support-Team, considering that if it means to move the
UPS, the connected cables will have the needed clearance.
• Do not put materials over the equipment or parts that obstruct
the correct visualization of the synoptic.
• be careful to not wet it, because it is not waterproof. Do not allow
entering any kind of liquids in. if accidentally the outside of the
machine comes into contact with liquids or salt air, dry it with a
soft and absorbent cloth.
• To clean the equipment, wipe over a damp cloth and then dry it.
Avoid sprinkling or spillage that could enter through the slots or
cooling grids, which may cause fire or electric shock.
Do not clean the equipments with products that could have al-
cohol, benzene, solvent or other inflammable substances, or they
