Section 4: Installation and Setup
4.1 Preparation
Installing and wiring any model within the EB1s Series power supplies into an enclosure may be accomplished by
connecting input and output wiring to the appropriate connectors of the power supply. The AC input cord of the
power supply mates with standard receptacles of the region served. All other connectors on the front panels of
the modules mate with industry-standard connectors widely available and used within the broadband industry.
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 overcurrent 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.

When the power supply enclosure is located on a utility pole, suitable lifting equipment shall be employed
during installation and service activities.

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 enclosures of either pole or ground-mount
configuration. Observe the following procedures during installation of any EB1s Series power supply.
The EB1s 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 configured EB1s battery voltage. Power supply
ratings may be verified from the nameplate on the left side panel near the power cord.
4.2 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
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.
1. The AC utility conductors installed in the service entrance box must contain a safety ground conductor.
The power supply installer should verify that this grounding conductor is in place, having been installed
along with the AC utility input.
