Electrical Safety Information
➤
Before powering on the unit, all grounding terminals, extension cords, 
and devices connected to it should be connected to a protective 
ground via a ground socket. Any interruption of the protective 
grounding is a potential shock hazard and may cause personal injury.
➤
Whenever the ground protection is impaired, the unit is not to be used 
and must be secured against any accidental or unintended operation.
➤
Only fuses with the required rated current and specified type 
(IEC, 250 V, 2 A, fast blow,5 mm x 20 mm (0.197 in x 0.787 in)) may be 
used for replacement. Do not use repaired fuses or short-circuited fuse 
holders.
➤
Any adjustments, maintenance, and repair of opened units under 
voltage should be avoided and carried out only by skilled personnel 
aware of the hazards involved. Do not attempt internal service or 
adjustment unless another person qualified in first aid is present. Do 
not replace any components while power cable is connected.
➤
Operation of any electrical instrument around flammable gases or 
fumes constitutes a major safety hazard.
➤
Capacitors inside the unit may be charged even if the unit has been 
disconnected from its electrical supply.
AC Requirements
The PM-1600 can operate from any single-phase AC power source between 
100 V and 240 V (50 Hz/60 Hz). The maximum input current is 2 A.
