Chapter C - INSTALLATION INSTRUCTIONS
1) Before installation, check that none of the components of the inverter is live.
2) If the inverter is installed outside a switchgear, enclosure or electrical room, it must
be equipped with a protective cover as provided by the regulations for IP21
protection class. For installations in a switchgear, enclosure or electrical room, the
cable protection plate is normally not necessary.
3) Route the motor cables clear of other cables:
• Avoid placing the motor cables in long parallel lines close to other cables
• If the motor cables run in parallel with other cables, note the minimum distances
between the motor cables and other cables given in table below.
• The given distances also apply between the motor cables and signal cables of other
systems.
• The maximum length of the motor cables is 990 ft. on all units.
• The motor cables should cross other cables at an angle of 90 degrees.
4) If cable insulation checks are needed, see Chapter D.
5) Connect the cables:
• Strip the motor and mains cables as shown in Table 3-2 and Figure 3-2.
• Remove the screws of the cable protection plate.
• Make holes into and pass the cables through the rubber grommets on the bottom of
the power unit.
• Connect the mains, motor and control cables into their respective terminals.
• For Information on cable installation according to UL regulations see Chapter D
• Make sure that the control cable wires do not come in contact with the electronic
components of the unit.
• If an external brake resistor is used, connect its cable to the appropriate terminal.
• Check the connection of the ground cable to the motor and the inverter terminals
marked with ground symbol.
