WIRING
WARNING !
UPS installation and connection must be performed by QUALIFIED SERVICE PERSONNEL
only.
Refer to the “
Safety prescriptions - Installation
” described on
Section 1
.
4.7.1 Mains input connection
WARNING !
Ensure that the AC and DC external isolators are OFF and locked out to prevent their inadvertent
operation.
Do not apply power to the equipment prior to the commissioning by a qualified service engineer.
Before any other input connection, connect and check the earthing wire.
The
mains input
power connection can be common or separate for
bypass supply
and
rectifier input
,
depending on the electrical system provided by the customer.
Common input Rectifier & Bypass
The
same power source
is to be used for both
bypass supply
and
rectifier input
(input
F3
).
Bear in mind that when the
mains fuses
are opened there is a supply failure to the
rectifier
as well as to
the
bypass
and
manual bypass switch
.
In this case, the interconnection links
BR1
,
BR2
and
BR3
on the input terminals or bus
bars MUST REMAIN CONNECTED.
Separate input Rectifier & Bypass (recommended)
The
bypass
and rectifier use different power sources (
F1
and
F2
inputs).
In this case, when the
rectifier-input fuses
are opened, the
automatic bypass
and the
manual bypass
are supplied by the other connection.
In this case, REMOVE the interconnection links
BR1
,
BR2
and
BR3
on the input terminals
or bus bars. See
Fig. 4.8.3-2
and
Fig. 4.8.4-2
.
