4.6 Stripping the Cables

Stripping the data cables is necessary if the cables are not preinstalled with connectors. When planning to ground the cable shield
directly to ground with 360 ° connection (see 

5.2.1 Jumpers in the OPTC3/C5 Option Board

), do step 3 and strip the cable shield

visible. Otherwise skip step 3 when installing cables.

Procedure

Remove approximately 15 mm of the gray shield of the fieldbus cable. Repeat for the 2 cables.

Remove approximately 15 mm of the shield of the fieldbus cable. Repeat to all data cables.
Strip the cables for approximately 15 mm to put them in the terminals. Do not keep more than 10 mm of the cable
outside the terminals.
When grounding the cable shield directly to ground, strip the cable at such a distance from the terminal that it is
possible to attach it to the frame with the cable clamp. Strip the cable at a maximum length of 15 mm. Do not
remove the aluminum shield of the cable.

Connect the cable to the correct terminals on the terminal block of the option board.
Install strain relief and make the shield grounding. See more in

4.7 Grounding the Cable Shield

Equipotential bonding refers to using metal parts to make ground potential everywhere in the installation the same, the system
ground. If the ground potential of all the devices is the same, you can prevent current from flowing through paths that are not
designed to have current. You can also shield cables efficiently.
An error in the equipotential bonding can cause bad quality or malfunction of the fieldbus communication. It is not easy to find an
error in equipotential bonding. It is also not easy to correct errors in large installations after commissioning. Thus, in the planning
phase it is important to plan the installation to get good equipotential bonding. In the commissioning phase, make the equipoten-
tial bonding connections carefully.
Do grounding with low HF impedance, for example, via backplane mounting. If ground connection wires are necessary, use wires
that are as short as possible. Note that paint coating acts as an insulator on metal and prevents grounding. Remove paint coating
before doing grounding.
This chapter describes the principles of cable shield grounding. Notice that the internal RS485 fieldbus in VACON 100

does not have jumpers for grounding options.
Connect the cable shield directly to the frame of the AC drive (see 

Illustration 9

 and 

Illustration 11

).
