Section 4:
Installation
and
Setup
Installing and wiring any model within the EDP Double Conversion series of power supplies into an enclosure may be
accomplished by connecting input and output wiring to the appropriate connectors of the power supply. The four
conductors of the circular Power connector are to be used to connect the UPS to the cabinet
’
s internal Utility Line and
Load terminal block buses. If used with a mating transfer switch, the circular harness attached to the transfer switch is to
be used to provide power to the UPS and points of connection for AC power and load. All other connectors on the front
panels of the UPS mate with industry-standard connectors widely used. Moreover, connectors used in this power supply
mate with accessory harnesses and assemblies designed and manufactured by Multilink Inc. Refer to the
OPTIONS
section of these instructions for further information.
In all installations, the following conditions apply and must be observed:
•
A service disconnect switch containing over-current protection devices such as circuit breakers or fuses with
appropriate AIC (amperes
–
interrupting capacity) rating should be placed between the AC utility source and the
service entrance device for the power supply. Where used, the disconnect switch must be installed in compliance
with all national, state and local codes as required.
•
For outdoor installations, the AC utility conductors connected to the power supply service entrance device shall
be physically protected through an appropriate restraining device and conduit, consistent with local codes and
practices.
•
Permission to mount the power supply enclosure at any site shall be made in accordance with all legal
requirements and local practices of the area.
This power supply is designed for use in both existing and new ground-mount enclosures. Observe the following
procedures during installation of any EDP Double Conversion series power supply.
Preparation
:
The EDP Double Conversion series power supplies have been factory assembled, tested, and prepared as a complete
product ready for installation within an enclosure. The installer must verify that the correct type of AC power
receptacle is installed in the enclosure for the input service and power supply selected for use at any given site.
Additionally, the battery strings installed in the enclosure must match the EDP Double Conversion model specific
battery voltage. Power supply ratings may be verified from the nameplate on the top of the power supply near the AC
Input circuit breaker.
Grounding
:
Safety ground and earth ground connections must be in place for the power supply and enclosure for both personal
safety and operational considerations. During power supply and/or enclosure installation, the following grounding
connections must be provided or verified.
CAUTION /
ATTENTION
Failure to provide and connect adequate safety and earth grounds at each installation site may result in
improper power supply operation or permanent damage to the power supply itself. Grounding facilities
and connections must conform to appropriate national codes and/or local practices.
Si vous ne fournissez pas et ne connectez pas des zones de sécurité et de mise à la terre adéquates sur
chaque site d'installation, vous risquez d'endommager le bloc d'alimentation ou d'endommager l'ali-
mentation électrique elle-même. Les installations de mise à la terre et les connexions doivent être con-
formes aux codes nationaux et / ou aux pratiques locales appropriées.
