TC12 Installation, Commissioning & Maintenance Handbook 

The Power supply fitted to every PSU board used in the system (part number 
667/7/22631/000, manufactured by Daren Electronics PLC type PP40-30). An 
internal link in this power supply needs to be set for the nominal mains voltage. 
See Figure 9 for link setting; set to 110 V position for 98 V to 132 V mains voltage 
range, set to 240 V for 198 V to 264 V mains voltage range.

Ensure that the correct variant has been supplied e.g. 
  666/1/02243/000 for the UK. 
  666/1/02243/000 or 666/1/02243/001 for non-UK (the /001 variant includes extra 
components; metal oxide varistors and gas discharge tubes, for surge protection). 
 
The switches on the Modem PCB should be set as follows: 
 

Note:  The tables referred to below contain 0's to indicate open switches and 1's 

to indicate closed switches. For all the switches push the switch down to 
the left for a 0 and down to the right for a 1. The 0 and 1 position is shown 
on the silkscreen underneath switch SW7.
