RCS20 M:N Redundancy Switch
Installation
2.4.3 Electrical
Make sure that the site has adequate electrical power. The power sources must be properly grounded
and must be free from electrical interference as much as possible.
If a redundant configuration is to be used, then each power cord on the RCS20 must be plugged into its
own separate power circuit. Each circuit must have its own independent circuit breaker.
Grounding is automatic when the three-prong power plug is inserted into a power receptacle. Verify by
testing that there is no voltage present between the chassis of the Switch and the power line ground.
WARNING – RISK OF PERSONAL INJURY AND EQUIPMENT DAMAGE
Do not bypass or defeat the protective ground. Do not use a three-to-two-prong adapter.
The RCS20 is rated for a nominal operating range of 100-240 volts AC; for the appropriately equipped DC
option, nominal operating range is 48 ±5 volts DC. The unit has a maximum power consumption of 250
watts.
The installation and connection to the line supply must be made in compliance to local or national wiring
codes and regulations.
The RCS20 is shipped with line inlet cables suitable for use in the country of operation. If it is necessary
to replace these cables, ensure the replacement has an equivalent specification.
Examples of acceptable ratings for the cables include HAR, BASEC and HOXXX-X.
Examples of acceptable connector ratings include VDE, NF-USE, UL, CSA, OVE, CEBEC, NEMKO,
DEMKO, BS1636A, BSI, SETI, IMQ, KEMA-KEUR and SEV.
2.4.3.1
Grounding
CAUTION
PROPER GROUNDING PROTECTION IS REQUIRED: The installation instructions
require that the integrity of the protective earth must be ensured and that the
equipment shall be connected to the protective earth connection at all times.
It is therefore imperative during installation, configuration, and operation for the user to
ensure that the unit has been properly grounded using the ground stud provided on
the rear panel of the unit.
In Finland: "Laite on liitettävä suojamaadoituskoskettimilla varustettuun pistorasiaan."
In Norway: "Apparatet må tilkoples jordet stikkontakt."
In Sweden: "Apparaten skall anslutas till jordat uttag."
