Option 1: Vertical separators and spacers

Vertical separators are used if a vertical subdivision of the Energy Chain® interior is required. By standard, vertical separators are assembled every other Energy Chain® link.
NOTE: Observe a lateral spacing of at least 1.26 in. (32mm) for Energy Tubes and .63 in. (16mm) for Energy Chain®. There is no minimum spacing needed for side plates
Exception: Minimum spacing
Locking separator 6008 = .91” (23 mm)

Standard separator 6401 for Energy Chains®
This separator offers safe stability due to its wide base design, also when used with thick cables or hoses.

Locking separator 6408 for Energy Chains®
This separator is used for applications that are exposed to extremely high humidity. The clamp at the side serves to uniformly align the separators. In order to avoid destroying the separators when opening the Energy Chain®, make sure all separators are identically aligned.

NOTE ON SPACERS
Vertical separators are adjustable, but can be fixed in position by means of a spacer. Spacers are most often necessary for side mounted applications. The available inner height is reduced by .08” (2mm) per spacer (for example if one spacer is placed on either side of the separator, the overall inner height is reduced by .16” (4mm). To avoid this, place the spacers on the outside of the opening crossbar (not for long travels).

Option 2: Shelves

Energy Chains® and Energy Tubes can be subdivided both vertically and horizontally using the various interior separation elements.

Side plates 6002
This component is used to form the basic pattern of a shelf system.

Vertical separator 6403
This component is used to form the basic pattern of a shelf system.

Slotted separator 6405
This separator can be retrofitted into an existing interior separation system without removing the shelves, as long as these shelves fit into any of the 13 middle slots

Shelves 420-XX
These components form the basic pattern of a shelf system. Shelves of various widths can be arranged at 7 different heights in .28” (7mm) increments

Guide troughs

Guide troughs made of steel

1. Guide trough (blue)
2. Glide bar (black)
3. Assembly set (red)
4. Individual fastening without C-profile
5. Length of profile rail

Guide troughs are used for applications in which the upper run of the Energy Chain® glides on the lower run. The following components are required if the igus® steel guide trough is used.Guide trough without glide bars part no. 98-30, guide trough with glide bars part no. 98-31. Installation sets as a joint connection part no. 98-50. XX
.XX indicates the length of the C-profiles on which the guide trough is mounted.The standard length of the trough components and glide bars is 6.56 ft (2 m). The required total length of the guide trough is determined by the travel.
