68 Installation checklist
Drive option modules and other components
Type and number of option modules and other equipment is correct. Option modules
and other equipment are not damaged.
Option modules and terminals are labelled correctly.
The placement of option modules and other equipment inside the cabinet and on the
cabinet door is correct.
The mounting of option modules and other equipment is correct.
Internal cabling of the cabinet assembly
Main circuit:
• AC supply input cabling is ok.
• AC output cabling is ok.
• Supply for brake resistor (if used) is ok.
Cable types, cross-sections, colors and optional markings are correct.
Cabling is not susceptible to interference. Check the twisting of cables and cable
routes.
Connection of cables to devices, terminal blocks and drive module circuit boards:
• Cables are connected to terminals tight enough. (Pull the conductors to check.)
• 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.
• The control unit is wired properly to the drive module.
• The control panel cable is connected correctly.
Cables are not lying against sharp edges or bare live parts. Bending radius of fiber
optic cables is 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 agree with 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.
