H-Max Series Variable Frequency Drive
WARNING
The frequency inverter outputs (U, V, W) must not be
connected to the input voltage (destruction of the
device, risk of fire).
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.
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
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
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!
DANGER
