Peripheral Wiring
The following illustrates the various peripherals that could be required when using a Variable Speed Drive or Solar Drive:
The following illustrates the various components of each of the peripherals:
The following describes how to wire each respective peripheral component to the Variable Speed Drive or Solar Drive:
Input (Line) / Output (Load) EMC/EMI Filter (NOISE FILTER)
- The Line side typically includes three Phase Terminals and an Earth Terminal. The Load side typically only includes three Phase Terminals.
- For Input (Line) Filter – connect the Power Supply to the side where there are three Phase Terminals and an Earth Terminal and the other three Phase Terminals to the Drive.
- For Output (Load) Filter – connect the Drive to the side where there are three Phase Terminals and an Earth Terminal and the other three Phase Terminals to the Motor.
- Incorrect wiring could cause damage to the Drive or capacitors inside the filter.
- Install close to the Drive.
- Do not connect the Earth Terminal to the Drive.
- Can be used when using multiple motors with a single Drive.
- Do not install a Step Up/Down Transformer before or after an Input or Output Filter.
Input (Line) / Output (Load) Reactor/Choke (HARMONIC FILTER)
- The Line side typically includes three Phase Terminals located at the Top of the Windings. The Load side typically includes three Phase Terminals located at the Bottom of the Windings. In some cases, instead of terminals connected directly to the windings, Terminal Blocks are available for connections, the first terminal being the Line Terminal for a phase and the subsequent Terminal being the Load Terminal for the same phase.
- For Input (Line) Reactor/Choke – connect the Power Supply to the three Phase Terminals located at the Top of the Windings and the Bottom three Phase Terminals to the Drive.
- For Output (Load) Reactor/Choke – connect the Drive to the three Phase Terminals located at the Top of the Windings and the Bottom three Phase Terminals to the Motor.
- Incorrect wiring will affect the reactance value and impact performance.
- For larger kW G3 Series VSDs, Output Reactors are recommended, for G5 Series, Input Reactors are recommended.
- Silicone Steel Core temperatures should never exceed 100 °C, otherwise install a cooling fan for forced air cooling to prolong the service life of the Reactor/Choke.
- Install close to the Drive.
- Do not connect the Earth Plate to the Drive.
- Can be used when using multiple motors with a single Drive.
- Do not install a Step Up/Down Transformer before or after an Input or Output Choke.
* Please Note: The inductance and the design frequencies of Input Reactors and Output Reactors are different. If an Output Reactor is used as input, the harmonic suppression effect will be reduced. If an Input Reactor is used as output, the reactor temperature will be higher, and the voltage drop will increase. The Drive will not be affected, but it is not ideal to swop any of these reactors.
SineWave Filter
- The Line side typically includes three Phase Terminals connected to the Windings ONLY. The Load side typically includes three Phase Terminals connected to the Windings AND the Capacitors. In some cases, instead of terminals connected directly to the windings, Terminal Blocks are available for connections, the first terminal usually being the Line Terminal for a phase and the subsequent Terminal being the Load Terminal for the same phase. Connect the Drive to the three Line Side Terminals and the Motor to the three Load Side Terminals.
- Incorrect wiring may damage the Drive (and could cause Drive alarm – Err02 / Err04 / Err40)
- Silicone Steel Core temperatures should never exceed 100 °C, otherwise install a cooling fan for forced air cooling to prolong the service life of the SineWave Filter.
- Install close to the VSD.
- Do not connect the Earth Plate to the Drive.
- Can be used when using multiple motors with a single Drive.
- Can install a Step Up/Down Transformer after a SineWave Filter (install Transformer close to SineWave Filter) – this is however not recommended as it may affect the performance of the SineWave Filter.
* Installation Spacing – Please see the Drive spacing requirements for the specific Drive to be used with the peripheral and apply the same spacing logic for the peripheral.
