LOCATION AND ENVIRONMENT - continued
Power Supply
All three major parts of the system - Switcher Mainframe, Router Mainframe, and Control Panel -
have the option to be fitted with dual power supplies. In each case the unit will work happily with a
single power-supply connected if required.
For safety a mains earth connection MUST be provided.
The unit has auto-ranging mains input, and can be connected to any standard AC supply between
115v and 230v 50/60Hz without adjustment.
Fusing
The control panel is protected by a 4 amp, and the mainframe by a 5 amp, anti-surge (slow-blow)
fuse located in the mains inlet / power switch assembly, see diagram below.
