MECHANICAL INSTALLATION

Installation in technical room
For technical room installation, the drive can be mounted with an extension box (IP20). The drive should
be mounted vertically. It should be well fastened through the anchorages to avoid any movement. The
input inductances (CHOKE) delivered with the drive must be mounted vertically aside the drive to
ensure a correct operation. They will never be installed aligned under or above the drive to avoid
crossing the power cables or a cooling defect. The maximum length of the cables between the chokes
and the drive must be 3 m.
The inductance connection must be done with aluminum plates, with nickel-plated copper plates, or
plain copper plates but using contact paste in order to prevent galvanic corrosion between copper and
aluminum. The screw attachment of the connection plates and the inductance aluminum terminal must
be protected from humidity by applying petroleum jelly on the screw thread, the washer and nut.
The following picture shows the correct position of the inductances:
The following picture shows the vertical clearances depending on the power range:
