2.2.1 Test Data Sheet
Each RCS20 M:N Redundancy Switch system is shipped with a Test Data Sheet. This report contains
information on the results of the Switch quality control testing. The report also includes information
pertaining to the system settings that were made at the factory. It is recommended that the customer/user

Removal and Assembly
Carefully unpack the unit and ensure that all of the above items are in the carton. If the available AC
mains power at the installation site requires a different cordset from those included in the package, then a
suitable and approved cordset (for the country where the equipment is to be installed) will be required
before proceeding with the installation.
Should the Power Cable/AC Connector be of the wrong type for the installation, either the cable or the
power connector end should be replaced. The power supply itself is designed for universal AC
application. See specifications for appropriate voltages and currents.
