Environmental
The CDM-550T must not be operated in an environment where the unit is exposed to
extremes of temperature outside the ambient range 0 to 50°C, precipitation, condensation,
or humid atmospheres above 95% RH, altitudes (un-pressurised) greater than 2000
metres, excessive dust or vibration, flammable gases, corrosive or explosive atmospheres.
Operation in vehicles or other transportable installations which are equipped to provide a
stable environment is permitted. If such vehicles do not provide a stable environment,
safety of the equipment to EN60950 may not be guaranteed.
Installation
The installation and connection to the line supply must be made in compliance to local or
national wiring codes and regulations.
The CDM-550T is designed for connection to a power system that has separate ground,
line and neutral conductors. The equipment is not designed for connection to power
system which has no direct connection to ground.
The CDM-550T is shipped with a line inlet cable suitable for use in the country of
operation. If it is necessary to replace this cable, ensure the replacement has an equivalent
specification. Examples of acceptable ratings for the cable 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
