Power Connection
The rear panel of the ND 231 B contains a connecting jack for
a power cord with Euro connector (power cord included in
items supplied).
Minimum cross section of the power cord: 0.75 mm 2
Power supply: 100 Vac to 240 Vac (–15% to +10%)
50 Hz to 60 Hz (±2 Hz)
A voltage selector is therefore not necessary.
Danger of electrical shock!
Unplug the power cord before opening the
housing. Connect the grounding conductor.
Do not interrupt the grounding conductor.
Danger to internal components!
Do not engage or disengage any connections
while the unit is under power. Use only original
replacement fuses.
To increase noise immunity, connect the ground
terminal on the rear panel to the central ground
point of the machine.
