Re: [CZsynth] CZ Voltage Selector to handle 220v and 110v

2015-08-31 by Daniel Forró

Hi, Edward,

not so dangerous when we keep basic rules:

- do everything at once, step by step, without interruptions  
(especially when somebody can touch the instrument, or switch it on  
when you are not there or so - I've heard about such cases)

- check, check, check always and again

- keep away from the open machine all metal tools, or anything, which  
could fell inside during the work, and be also aware not to fell  
inside - keep order at your working place

- keep away curious children or pets

- work with the highest concentration and very carefully - even  
experienced person can do a fatal mistake when opened machine is  
switched on (I speak from my own experience after having good luck  
more times in my life  to survive few high voltage shocks without  
injury - that was good lesson)

- don't touch anything in mains circuit with naked fingers

- !!! disconnect the cord from mains !!!

- wait some time for discharging PSU caps

- if you have no experience with high voltage, never switch on the  
opened machine

We want to hear about you tomorrow :-)
