4.7 ELECTRICAL WIRING

WARNING !

UPS installation and connection must be performed by QUALIFIED SERVICE
PERSONNEL only.
It is the responsibility of the installation technician to ensure that all local and
national electric codes are adhered to.
Refer to the “Safety prescriptions - Installation
” described on Section 1.

4.7.1 Utility input connection

NOTE !

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 grounding wire.


The UPS has available input terminations for the Rectifier and Bypass.
The unit may be powered from a Common Input source or Dual Input sources if desired.

Common Input Utility Rectifier & Bypass

Fig. 4.7.1-1 Common Input Utility Rectifier & Bypass (option)

The same power source is to be used for both
Bypass Supply and Rectifier Input (input F3).

Bear in mind that when the Utility 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.

Dual Input Utility Configuration Rectifier & Bypass (option)

Fig. 4.7.1-2 Dual Input Utility Rectifier & Bypass

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.

Always verify that the received UPS is as per the configuration ordered.
While installing UPS dual source, the interconnection links BR1
, BR2 and BR3 MUST
BE REMOVED. See Fig. 4.8.2-2 & 4.8.4-2
.
