Warnings CAUTION Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed F7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance. Then wait for at least 5 minutes after all LEDs have gone out. Do not perform a withstand voltage test on any part of the Varispeed.
Safety Precautions and Instructions General Please read these safety precautions and instructions for use thoroughly before installing and operating this inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed. Live and hot inverter components may be accessible during operation. Removal of housing components, the digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installation or operation.
Electrical Connection Carry out any work on live equipment in compliance with the national safety and accident prevention regulations. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding, grounding, filter arrangement and laying of cables. This also applies to equipment with the CE mark.
Laying Cables Measures Against Line-Borne Interference: Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as close to each other as possible, with cables kept as short as possible. Use a power cable with well-grounded shield. For motor cables up to 50 meters in length use shielded cables. Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g. metal plate).
Installation Mechanical Installation Unpacking the Inverter Check the following items after unpacking the inverter. Item Has the correct Inverter model been delivered? Is the Inverter damaged in any way? Are any screws or other components loose? Method Check the model number on the nameplate on the side of the Inverter. Inspect the entire exterior of the Inverter to see if there are any scratches or other damage resulting from shipping. Use a screwdriver or other tools to check for tightness.
Installation Orientation Install the Inverter vertically so as not to reduce the cooling effect. When installing the Inverter, always provide the following installation space to allow normal heat dissipation.

Sinking/Sourcing Mode (NPN/PNP Selection) The input terminal logic can be switched over between sinking mode (0-V common, NPN) and sourcing mode (+24V common, PNP) by using the jumper CN5. An external power supply is also supported, providing more freedom in signal input methods.
Wiring Main Circuit Inputs Installing Fuses To protect the inverter, it is recommended to use semiconductor fuses like they are shown in the table below.

• If an earth leakage breaker is used, it should be able to detect all kinds of current in order to ensure a safe earth leakage current detection • A magnetic contactor or other switching device can be used at the inverter input. The inverter should not be powered up more than once per hour. • The input phases (R/S/T) can be connected in any sequence.

Troubleshooting General Faults and Alarms Faults and Alarms indicate unsusal inverter / application conditions. An alarm does not necessarily switch off the inverter but a message is displayed on the keypad (i.e. a flashing alarm code) and an alarm output can be generated at the multi-function outputs (H2-01 and H2-02) if programmed. An alarm automatically disappears if the alarm condition is not present anymore.
