Safety
To ensure safety of the operator the equipment has been designed to comply with the following
safety standard;
EN 60950
Safety of information technology equipment, including electrical business machines.
Before operation the user must ensure that the installation complies with the information given.
The equipment is designed to operate in a static 19 inch rack system conforming to IEC 297-2.
Operation of the equipment in transportable vehicles equipped with the means of providing a
stable environment is permissible. Operation of the equipment on board vehicles, ships or aircraft
without means of environmental conditioning will invalidate the safety compliancy; please contact
the factory for further advice. Operation of the equipment in an environment other than that stated
in the specifications will also invalidate the safety compliancy. The equipment must not be
operated above 2000 metre altitude, extremes of temperature; excessive dust, moisture or
vibration; flammable gases; corrosive or explosive atmospheres.
INSTALLATION
The equipment is classified in EN 60950 as a pluggable equipment class A for connection to the
mains supply, as such it is provided with a mains inlet cord suitable for use in the country of
operation. In normal circumstances this will be of an adequate length for installation in the rack. If
the mains cord proves to be too short then any replacement must have a similar type fuse (if
fitted) and be manufactured to similar specification: check for HAR, BASEC or HOXXX-X ratings
on the cable. The connector ends should be marked with one of the following : BS1636A (UK free
plug 13 amp); BSI, VDE, NF-USE, UL, CSA, OVE, CEBEC, NEMKO, DEMKO, SETI, IMQ, SEV
and KEMA-KEUR for the IEC 6 amp free socket. Schuko and North American free plugs must
have similar markings.
The installation of the equipment and the connection to the mains supply must be made in
compliance to local or national wiring regulations for a category II impulse over voltage
installation. The positioning of the equipment must be such that the mains supply socket outlet for
the equipment should be near the equipment and easily accessible or that there should be
another suitable means of disconnection from the mains supply.
The equipment is designed to operate from a TN type power supply system as specified in EN
60950. This is a system that has separate earth, line and neutral conductors. The equipment is
not designed to operate with an IT power system which has no direct connection to earth.
