8. 1. Cable routing practices

When wiring Altivar 61 drives to a BACnet network, follow all wiring practices required by national and local electrical codes. Also observe

the following guidelines:

• Avoid areas of high temperature, moisture, vibration, or other mechanical stress.

• Secure the cable where necessary to prevent its weight and the weight of other cables from pulling or twisting the cable.

• Use cable ducts, raceways, or other structures to protect the cable. Use these structures for signal wiring paths. They must not contain

power wiring.

• Avoid sources of electrical interference that can induce noise into the cable. Use the maximum practicable separation from such sources.

When planning cable routing within a building, follow these guidelines:

• Maintain a minimum separation of 1 m from the following equipment:

- air conditioners and large blowers,

- elevators and escalators,

- radios and televisions,

- intercom and security systems,

- fluorescent, incandescent, and neon lighting fixtures.

• Maintain a minimum separation of 3 m from the following equipment:

- line and motor power wiring,

- transformers,

- generators,

- alternators.

When wiring in electrical equipment rooms or large electrical equipment line-ups, observe the following guidelines for cable segregation

and separation of circuits:

• Use metallic conduit for drive wiring. Do not run control network and power wiring in the same conduit.

• Separate non-metallic conduits or cable trays used to carry power wiring from metallic conduit carrying low-level control network wiring

by at least 300 mm.

• Separate metallic conduits carrying power wiring or low-level control network wiring by at least 80 mm.

• Cross the metallic conduits and non-metallic conduits at right angles whenever power and control network wiring cross.

• Attenuate conducted emissions from the drive to the line in some installations to prevent interference with telecommunication, radio, and

sensitive electronic equipment. Such instances may require attenuating filters. Consult the Altivar catalog for selection and application of

these filters.

8. 2. Card connector pinout

• The cable sheath should be stripped off by about 10 mm (0.4 in).

• For wiring the terminals, use a slotted screwdriver with a 0.6 mm (0.02 in) thick and 3.5 mm (0.14 in) width blade.

• Tightening torque for the terminal block is 0.5 to 0.6 N-m (0.37-0.44 ft-lb)
