Riello UPS Sentinel Dual (High Power) (3.3 - 10 kVA) - Manual (Page 6)

GB SAFETY GB
This part of the manual contains precautions that must absolutely be followed as they
relate to SAFETY.
a) The UPS MUST NOT BE OPERATED WITHOUT A GROUND CONNECTION. Do not pull out
the plug from the mains socket as this would remove the safety earth for the UPS and for the
equipment it is powering.
b) Avoid connecting the outlet neutral line to the input neutral or to the earth as this could cause
malfunctions.
c) The UPS internally generates DANGEROUS electrical voltages. All maintenance operations must
be carried out SOLELY by qualified operators.
d) The UPS contains a power source inside: the batteries. There may be live voltage on the output
sockets even without connecting the UPS to the mains.
e) The total battery voltage may generate an electric shock. All batteries substituted must be considered
as TOXIC WASTE and treated accordingly. Do not throw the battery pack into a fire: it could
explode. Do not try to open the battery pack - these batteries are maintenance-free. In addition the
electrolyte is dangerous to the skin and eyes and may be toxic.
f) Do not turn on the UPS if a liquid is seen to be leaking, or if a white powder residue can be seen.
g) Prevent water, liquids in general and/or other foreign matter from entering the UPS.
h) The detachable power cord can be considered to be a sectioning device. Make sure to leave enough
free space at the rear of the UPS in the vicinity of the cable connection point for easy disconnection.
i) In the presence of a hazard, switch off the UPS by the switch on the front panel and remove the input
connection.
j) The UPS gives rise to a dispersion current of about 1 mA. To guarantee the maximum limit
dispersion current of 3.5 mA, make sure that the maximum dispersion current of the load is 2.5 mA.
Where the dispersion current of the load is in excess of this limit, have qualified personnel connect
the UPS to an IEC 309 standard, industry type power supply mains, which will be sized for a current
suitable for the UPS’s power rating.
k) For battery expansions, use only connectors supplied or authorized by the manufacturer.
l) The UPS in this range are designed for professional use and are therefore not suitable for use in the
home.
m) Provided that the neutral (N) and phase (F) indications for plugs
and sockets are respected, the UPS does not alter the existing
neutral arrangements when inserted in an installation. The
resistance of the neutral connection is less than 0.1Ω. The neutral
arrangements are however altered if there is an isolating
transformer or when the UPS works with the neutral sectioned
upstream.
The figure to the side indicates the exact position of the neutral pin
of the various plugs and sockets of the UPS.
