Voltage fluctuations of +6% to -15% are permissible.The supply voltage connector (11) is located on the rear of theinstrument (inlet connector for non-heating apparatus + ground wire).The instrument’s micro fuse (12) is located above this connector. Value:315 mAT; dimensions: 5 x 20 mm. Located above the micro fuse is thedouble-pole, primary on/off switch (13), which separates the KAL 200from the supply voltage.WARNING! Risk of Electrical shock! Failure to unplug the power supply cordbefore replacing the fuse may result in fatal injuries!10 1415161718111312
