M-Max Series Adjustable Frequency Drive
xii M-Max Series Adjustable Frequency Drive MN04020003E—October 2013 www.eaton.com
WARNING
The frequency inverter outputs (U, V, W) must not be
connected to the input voltage (destruction of the
device, risk of fire).
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Switch S1 must switch only when frequency inverter T1 is at
zero current.
WARNING
Carry out wiring work only after the frequency inverter
has been correctly mounted and secured.
WARNING
Electric shock hazard—risk of injuries!
Carry out wiring work only if the unit is de-energized.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Fire hazard!
Only use cables, protective switches, and contactors that
feature the indicated permissible nominal current value.
CAUTION
Debounced inputs may not be used in the safety circuit
diagram.
Ground contact currents in frequency inverters are greater
than 3.5 mA (AC). According to product standard IEC/EN
61800-5-1, an additional equipment grounding conductor
must be connected, or the cross-section of the equipment
grounding conductor must be at least 0.39 in
2
(10 mm
2
).
WARNING
The components in the frequency inverter’s power
section remain energized up to five (5) minutes after the
supply voltage has been switched off (intermediate
circuit capacitor discharging time).
Pay attention to hazard warnings!
WARNING
Discharge yourself on a grounded surface before
touching the control signal terminals and the controller
PCB. This protects the device from destruction by
electrostatic discharge.
WARNING
On the control signal and the connection terminals of the
frequency inverter, no leakage resistance tests are to be
performed with an insulation tester.
WARNING
Wait at least 5 minutes after switching the supply
voltage off before you disconnect a connection on the
connection terminals (L1, L2/N, L3, U/T1, V/T2, W/T3,
R+, R–) of the frequency inverter.
WARNING
Commissioning is only to be completed by qualified
technicians.
WARNING
Hazardous voltage!
The safety instructions on Page x must be followed.
WARNING
The components in the frequency inverter’s power
section are energized if the supply voltage (line voltage)
is connected. For instance: power terminals L1, L2/N, L3,
R+, R–, U/T1, V/T2, W/T3.
The control signal terminals are isolated from the line
power potential.
There can be a dangerous voltage on the relay terminals
(22 to 26) even if the frequency inverter is not being
supplied with line voltage (for example, integration of
relay contacts in control systems with 230 Vac).
WARNING
Following a shutdown (fault, line voltage off), the motor
can start automatically (when the supply voltage is
switched back on) if the automatic restart function has
been enabled.
