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 mains inlet cords suitable for use in the country of operation. In normal
circumstances they will be of an adequate length for installation in the rack. If a 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.
