Check that ...
Connection of cables to devices, terminal blocks and drive module circuit boards:
• Cables are connected to terminals tight enough by pulling the cable.
• Cable termination on terminals chaining is done correctly.
• Bare conductors are not too far outside the terminal causing an insufficient clearance or loss of shielding against
contact.
• JCU control unit is wired properly to the drive module.
• Control panel cable is connected properly.
Cables are not lying against sharp edges or bare live parts. Bending radius of fiber optic cables at least 3.5 cm
(1.38 in.).
The type, markings, insulation plates and cross connections of terminal blocks are correct.
Grounding and protection
The grounding colors, cross-section and grounding points of modules and other equipment match the circuit
diagrams. No long routes for pigtails.
Connections of PE cables and busbars are tight enough. Pull the cable to test that it does not loosen. No long
routes for pigtails.
Doors equipped with electrical equipment are grounded. No long grounding routes. From EMC standpoint best
result is achieved with a flat copper braid.
Fans that can be touched are shrouded.
Live parts inside the doors are protected against direct contact to at least IP2x.
Labels
The type designation labels and warning and instruction stickers are made according to the local regulations and
placed correctly.
Switches and doors
Mechanical switches, main disconnecting switch and cabinet doors function properly.
Installation of the cabinet
The drive cabinet has been fixed to floor and also from top to the wall or roof.
The ambient operating conditions meet the specifications given in chapter
The cooling air will flow freely in and out of the drive cabinet, and air recirculation inside the cabinet will not be
possible (air baffle plates are on place).
If the drive has been stored over one year: The electrolytic DC capacitors in the DC link of the drive have been
reformed. See page 124.
There is an adequately sized protective ground conductor between the drive and the switchboard.
There is an adequately sized protective ground conductor between the motor and the drive.
All protective ground conductors have been connected to the appropriate terminals and the terminals have been
tightened. (Pull the conductors to check.)
The enclosures of the equipment in the cabinet have proper galvanic connection to the cabinet protective earth
(ground) busbar; The connection surfaces at the fastening points are bare (unpainted) and the connections are
tight, or separate grounding conductors have been installed.
