Prosody X Installation guide
Appendix E:
Safety information
E.1
AC Power requirements
The rating plate details the permitted voltage and frequency range for that particular
unit.
CAUTION
Under no circumstance connect the Prosody X to a power source with voltage or
frequency different to that stated. Contact your local supplier for advice if your
power input is different to that shown on the rating label.
The Prosody X can operate with the following AC power inputs:
Power input type
AC chassis (Amps)
North America – 115VAC 60Hz
0.6 max, 0.2
continuous
UK and Europe – 230VAC 50Hz
0.3 max, 0.1
continuous
WARNING
THIS EQUIPMENT IS NOT DESIGNED FOR USE WITH AN I.T. POWER
SUPPLY (A POWER DISTRIBUTION SYSTEM THAT HAS NO DIRECT
CONNECTION TO GROUND, AND WHERE THE EXPOSED CONDUCTIVE
PARTS OF THE ELECTRICAL INSTALLATION ARE GROUNDED).
E.2
AC Power cords
The Prosody X is supplied with moulded IEC60320 input power cords. Within the
United Kingdom these will be ASTA (Association of Short Circuit Testing Authorities)
approved power cords with moulded 13A 3 Pin plugs. These should be fused at 5A.
Within Europe these will be moulded 3 Pin plugs with suitable European agency
approval marks. Additionally the cords will be <HAR> marked.
Within North America these will be moulded 3 Pin plugs with UL and CSA type
approval.
The power cords supplied will be terminated suitable for your local requirements. In
cases where no plug is fitted or if a plug needs to be changed, the plug may only be
fitted by a person competent to fit a plug of the type suitable for the required power
outlet. If a power cord needs to be replaced, an appropriately approved power cord
must be used.
E.3
Circuit definition
The Ethernet (Prosody X IP communication and Hardware Platform interface ) and
USB interfaces are Safety Extra Low Voltage (SELV) circuits. SELV circuits are so
designed and protected that under normal conditions the maximum voltage between
any two accessible circuit parts, one of which may be body or ground, does not
exceed 42.4 volts (peak AC) or 60VDC, even in the presence of a single fault.
E1/T1 interfaces are Telecommunication Network Voltage (TNV) circuits operating
within the limits of SELV. The E1/T1 interfaces have transient voltage protection
circuits built in.
