• 100V~
• 115V~
• 220-240V~
The mains voltage setting for the complete unit can be altered by re-wiring
the voltage jumper on the Main control PCB (connector P21). For re-wiring
the voltage jumper, refer to the Technical Manual.
NOTE
Please note that the ratings of the internal (as well as external) mains fuses
are depending on the selected voltage settings.
2.4.2 Mains frequency
The mains frequency is 50 or 60 Hz and is independent on the mains
voltage setting.
2.4.3 Internal mains fuse ratings
The unit is equipped with dual mains fuses (live and neutral). However, in
some areas it is not allowed to have a fuse in the neutral wire. The neutral
fuse is bypassed by default with the same voltage setting jumper (connector
P21). For details how to bypass the neutral fuse, see .
The ratings for the internal mains fuses are:
•
F1, F2= Schurter 0001.1014 10A/250V/FAST ACTING/HIGH BR CAP.
(100V, 115V)
•
F1, F2= Bussmann S501-10-R 10A 250V FAST ACTING/HIGH BR CAP.
(100V, 115V)
•
F1, F2= Schurter 0001.1012 6.3A/250V/FAST ACTING/HIGH BR CAP.
(220V – 240V)
•
F1, F2= Bussmann S501-6.3-R 6,3A 250V FAST ACTING/HIGH BR
CAP. (220V- 240V)
In the case that the neutral fuse is bypassed with the voltage jumper, the
neutral fuse can be left open.
2.4.4 External mains fuse recommendation
The recommendation for the external fuses are:
•
Units with 100V~ or 115V~ voltage setting: 16A, time lag
•
Units with 220-240V~ voltage setting: 10A, time lag
No other equipment should be connected to the same fused mains line as
the unit. In some countries an additional external fault current guard is also
required. Some electronic circuit breakers are very fast and can
unintentionally trip during the unit turn-on. This is fully normal and is due to
the unit’s mains transformer inrush current. Selecting a circuit breaker with a
higher current rating solves this nuisance.
Canada only:
•
External fuse: Max. 20A branch circuit fuse
2.4.5 External mains switch
Mains voltage supply for the dental unit shall be equipped with a separate
fixed assembled mains switch according to standard IEC 61058-1:2000 +
A1:2001 + A2:2007 complying with isolation distances for 4 kV requirements.
