•
The equipments provided with power cord with plug
and outlets, can be connected and used by personnel
without any kind of experience.
The equipments with power blocks have to be installed by
qualified personnel and it can be used by personnel with
not specific training, just with only help of this manual.
A person is defined as qualified, if it has experience of as-
sembling, commissioning and perfect control operating of
the equipment, if he has the requirements to do the job and
if has read and understand all the things described in this
manual, in particular the safety indications. Such preparation
is considered only valid if it is certified by our S.T.S..
•
Place the equipment the closest to the power supply and
loads to be supplied, leaving an easy access if it were needed
an urgent disconnection.
•
Warning labels should be placed on all primary power
switches installed in places away from the equipment to alert
the electrical maintenance personnel of the presence of a
SPS in the circuit
The label will bear the following text or an equivalent one:
Before working in this circuit.
•
Isolate the Uninterruptible Power System (SPS).
•
Check the voltage between all terminals including the
protective earth.
Risk of voltage feedback from SPS.
1.2.3.1. General safety warnings.
•
All connections and disconnections of the cables from the
equipment, including the control ones, will be done with no
power supply and the switches on rest, position «O» or «Off».
•
Shutdown the equipment completely by switching «Off» the
button of the control panel first. Next disconnect the cable
from the wall outlet..
•
Pay special attention to the labelling of the equipment
that warns about the «Electrical shock hazard». Inside
the equipment there are dangerous voltages, never open the
enclosure, the access has to be done by qualified staff. In
case of maintenance or fault, consult to the closest (S.T.S.).
•
Cross cable sections used to supply the equipment and loads,
will be according to the nominal current stated in the nameplate
label of the equipment, and respecting the Low Voltage Electro-
technical Regulations or standards of the country.
Use approved cables only
•
Protection Earth cable of the SPS drives the leakage
current of the load devices. An isolated earth cable has
to be installed as part of the circuit that supplies the equip-
ment. Cross cable section and its features will be same as
the power supply cables, but with green colour with or without
the yellow strip.
All outlets of the SPS has an earth bonding, duly connected
and those equipments with power blocks there is an exclusive
terminal for the load earth connection. When an outgoing dis-
tribution is done, i.e power strips, it is essential that they have
an earth terminal connected to each one of them.
It is essential that the cables that supplies the loads have the
earth connection cable.
Check the quality and availability of the earth, it has to be
between the defined parameters by the local or national
regulations.
•
For the smallest devices (the ones connected with the fore-
seen power cord with plug), the user has to check the wall
outlet corresponds with the type of supplied plug, with earth
duly installed and connected to the local protection earth.
•
During the normal SPS operation the power cord
cable can’t be disconnected from wall outlet, because
the protection earth of the own SPS would be disconnected
and also the earth from the loads connected to the output.
For this reason, the general protection earth cable of the
building or switchgear panel that supplies the SPS will not
be disconnected.
•
In small equipments (the ones connected with the foreseen
power cord with plug), check that the sum of the leakage currents
of the SPS and connected load/s do not exceed over 3,5mA.
•
The installation will have input protections sized to the cur-
rents of the equipment and stated in the nameplate label
(RCD devices type B and circuit breakers with C character-
istic or any other equivalent one).
Overload conditions are considered as a nonpermanent an
exceptional operating mode, so these currents will not be
kept in mind when sizing the protections.
•
Do not overload the SPS by connecting loads with inrush
consumptions at its output, like laser printers.
•
Output protection will be done with a circuit breaker of C char-
acteristic or an equivalent one.
It is recommended to distribute the output power, into four
lines as minimum. Each one of them will have a protection
circuit breaker sized to the quarter of the nominal power.
This kind of outgoing distributions will allow that any fault in
any device connected to the equipment, that makes a short-
circuit, will affect to the line with the faulty device only. An
uninterruptible power supply will be guaranteed to the rest of
connected loads, due to the protection tripping of the affected
line by the short-circuit only.
•
When replacing a fuse, do it for another of the same type, char-
acteristics format and size.
•
Under any concept the input power cord will be connected to the
output of the equipment, either directly or through other ways.
•
When supplying input voltage to a SPS with static by-
pass, although the inverter is still turned «Off» (deac-
tivated) it doesn’t mean that at the output there will not be
voltage.
So, to do it, the input switch will have to be turned «Off».
Put warnings of danger and/or emergency switches if the
safety Standards require it in your particular installation.
•
All power supply electrical cables have to be fixed to the
equipments and loads, interfaces, etc..., to unmovable parts
and in the way to avoid treads, trips on them or fortuitous
pulls.
•
CHASSIS or RACK mounted equipments are destined to be in-
stalled in a predetermined set to be done by professionals.
ˆ
The installation has to be designed and executed by qual-
ified 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.
ˆ
The equipments assembled in CHASSIS do not have
enclosure protection, even the power blocks are unpro-
tected.
ˆ
Some RACK mounted equipments do not have the power
blocks protected.
•
Never manipulate the equipment with wet hands.
