apacitor or varistor on the output side
Since HD3L output is PWM wave, it is strictly forbidden to connect capacitor for improving the power
factor or varistor for lightning protection to the output terminals so as to avoid HD3L fault trip or
component damage.
Contactors and circuit breakers connected to the output of HD3L
If circuit breaker or contactor needs to be connected between HD3L and the motor, be sure to operate
these circuit breakers or contactor when HD3L has no output, so as to avoid any damage to HD3L.
Running voltage
HD3L is prohibited to be used beyond the specified range of running voltage. If needed, please use
suitable voltage regulation device to change the voltage.
Capacitor energy storage
When the AC power supply is cut off, capacitor of HD3L sustains deadly power for a while. So to
disassemble HD3L that is powered, please cut off the AC power supply for more than 10 minutes,
confirm the internal charge indicator is off and the voltage between (+) and (-) of the main circuit
terminals is below 36V.
Generally, the internal circuit enables the capacitor to discharge. However, the discharging may fail in
some exceptions. In these cases, users need to consult Hpmont or our regional distributor.
Change three-phase input to single-phase input
For three-phase input controller, users should not change it to be single-phase input.
To use single-phase power supply, disable the input phase-loss protection function. And the
bus-voltage and current ripple will increase, which not only influences the life of electrolytic capacitor
but also deteriorates the performance of the controller. In that case, the controller must be derating
and should be 60% within rated value of controller.
Lightning surge protection
HD3L internal design has lightning surge over-current protection circuit, and has certain
self-protection capacity against the lightning.
