Multi-Station Power Supply
7
Note: ________________________________________________________________
Each DC power source should be independent of the other in order to have
power redundancy. If you do not require power redundancy, the unit can be
operated with a single power cable connected to a single DC power source.
In this case, either DC power block on the rear of the Multi-Station Power
Supply may be used for the connection.
______________________________________________________________________
Note: ________________________________________________________________
DC power cables should have a wire gauge of at least 14 and a 72VAC 13A
rating.

Installation in a Restricted Access Location in Finland
and Norway
Installation in a Restricted Access Location is required in Finland and Norway
for the Multi-Segment Power Supply. Because of concerns about unreli-
able earthing in Finland and Norway, this equipment must be installed in a
Restricted Access Location (RAL) in these countries. An RAL is dened as an
access that can be gained only by trained service personnel who have been in-
structed about the reasons for the restricted access and any safety precautions
that must be taken. In these cases, the use of a tool (such as lock and key) or
other means of security is required for access to this equipment.
Warnings and Symbols
Warnings on product
Two of these labels cover screws on the chassis top cover near the front
corners. They prevent you from taking the cover off without voiding
your warranty. You should not take the cover off because there are no
user-serviceable parts inside, and there is a danger of electrical shock.
