4 EN – Quick installation guide
5. Measure that the installation is de-energized.
• Use a multimeter with an impedance of at least 1 Mohm.
• Make sure that the voltage between the drive module input power terminals
(L1/U1, L2/V1, L3/W1) and the grounding (PE) busbar is close to 0 V.
• Make sure that the voltage between the drive module UDC+ and UDC- terminals
and the grounding (PE) terminal is close to 0 V.
6. Install temporary grounding as required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation work.
Select the power cables
Size the power cables according to local regulations to carry the nominal current given on
the type designation label of your drive.
Ensure the cooling
See table on page 9 for the losses and the cooling air flow through the drive. The allowed
operating temperature range of the drive without derating is -15 to +40 °C.
Protect the drive and input power cables
See table on page 9.
Installing the drive module and LCL filter module into a
cabinet
See appendix Step-by-step drawings for an installation example of standard drive
configuration in Rittal VX25 800 mm wide cabinet.
• Attach the plinth to the floor.
• Attach the cabinet frame to the plinth.
• Make the bottom plate with 360-degree grounding entries for power cables.
• Attach the bottom plate to the cabinet.
• Attach the punched section to the back of the cabinet frame.
• Attach the mounting brackets to the punched section.
• Install the pedestal to the LCL filter module.
• Install the cooling fan to the LCL filter module.
• Attach the LCL filter module pedestal guide plate to the cabinet bottom plate.
• Attach the telescopic insertion ramp to the pedestal guide plate.
• To prevent the LCL filter module from falling, attach its lifting lugs with chains to the
cabinet frame.
• Push the LCL filter module carefully into the cabinet along the telescopic insertion
ramp. Work preferably with help from another person as shown below. Keep a
constant pressure with one foot on the base of the module to prevent the module from
falling on its back
