Electrical Safety
The CDM-550T has been shown to comply with the EN 60950 Safety of Information
Technology Equipment (including electrical business machines) safety standard.
The equipment is rated for operation over the range 100 - 240 volts AC. It has a maximum power
consumption of 25 watts, and draws a maximum of 250 mA.
IMPORTANT
The user should observe the following instructions:
Fuses
The CDM-550T is fitted with two fuses – one each for line and neutral connections. These are
contained within the body of the IEC power inlet connector, behind a small plastic flap.
• For 230 volt AC operation, use T0.5A, 20mm fuses.
• For 115 volt DC operation, use T1A, 20mm fuses.
CAUTION
FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES
WITH THE CORRECT TYPE AND RATING.
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 (32 to 122°F), 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.
