Keep these instructions!
This document provides important safety instructions and a short instruction for how to
examine the UPS delivery and how to install the UPS. This quick guide is only meant to be
used as an installation checklist on site.
The intended audience of this document is experienced professionals who plan and do the
installation of the UPS.
Before you do work on the UPS, read the full installation instructions provided in the
Eaton 91PS/93PS UPS 8-40 kW User's and Installation Guide.
The full instructions are available for download at www.eaton.com/91psand93ps.
Operations inside the UPS must be done by an authorized Eaton Customer Service
Engineer or by qualified service personnel authorized by Eaton. There are no user-
serviceable parts inside the UPS.
The UPS operates with mains, battery or bypass power. It contains components that carry
high currents and voltage. A properly installed enclosure is earthed and IP20 rated against
electrical shock and foreign objects. The UPS is a sophisticated power system and only
qualified personnel are allowed to install and service it.
This UPS carries lethal voltages.
Batteries present a risk of electrical shock or burn from high short circuit current. Obey
the precautions.
Batteries may contain HIGH VOLTAGES, and CORROSIVE, TOXIC and EXPLOSIVE
substances. Because of the battery string the output receptacles may carry high voltage
even when the AC supply is not connected to the UPS. Read the shutdown instructions in
the User's and Installation Guide.
The UPS is powered by its own energy source (batteries). The output terminals may be
energized even when the UPS is disconnected from an AC source. To reduce the risk of
fire or electric shock, install this UPS in a temperature and humidity controlled, indoor
environment that is free of conductive contaminants.
Do not stack the 91PS/93PS C-model UPS cabinet on top of any other similar cabinet(s).
Do not stack anything on the top of the 91PS/93PS UPS cabinet. If the 91PS/93PS C-
model UPS cabinet is installed on a shelf, use necessary supports to prevent the UPS
from tipping or dropping.
