Chapter 9: IP-65 Option

9.2 Modifications to Meet IP-65 Classification

Outer link

The Cobra s800 Inverted robot has different seals for the IP-65 version. The outer link cover has been widened slightly to accommodate a larger seal.

The user connections are not available from the outside of the outer link on the IP-65 version.

Rather, the outer link cover must be removed to access these connections, and the connections

continue through the quill, rather than outside of the outer link. Refer to Removing/Installing

Outer Link Cover on page 128.

AIB/eAIB Cable Seal

The cables entering the AIB/eAIB have a special seal assembly to achieve IP-65 classification.

This is covered in Removing/Installing the Cable Entry Housing on page 124 and Installing the Roxtec Cable Seal Assembly on page 135.

Controller

This chapter applies to the Adept Cobra s800 Inverted robot, not to the Adept SmartController.

NOTE: The Adept SmartController must be installed inside a NEMA-1 rated enclosure.

Hard Stop, Rotation Range

Because the outer link cover has been widened, it cannot rotate as far as the standard inverted

Cobra. The hard stop has been enlarged to limit the outer link’s rotation (at J2), to prevent the outer link from hitting the robot body.

Refer to Table 7-4 for specifications for both Cobra versions.

9.3 AIB/eAIB Cable Seal Overview

There are two sealing assemblies for the AIB/eAIB cables.

One is a Roxtec Cable Seal Assembly. It consists of dense foam with adjustable-diameter holes for cables. The foam and cables are mounted in a housing that compresses the foam, thereby eliminating any gaps around the cables.

The other assembly is the cable entry housing, which provides access to the AIB/eAIB connections. Instructions for removal and reinstallation of the cable entry housing are provided in the next section. The Roxtec assembly is mounted through the cover of this assembly, and should never need to be disassembled.

In the event that a cable needs to be replaced, instructions are provided in Installing the Roxtec

Cable Seal Assembly on page 135 for removing and reinstalling the Roxtec assembly.

9.4 Removing/Installing the Cable Entry Housing

The Adept Cobra s800 Inverted robot IP-65 version has special sealing hardware at the

AIB/eAIB to ensure nothing can enter the inside of the robot or AIB/eAIB. If you need to remove

the cables from the AIB/eAIB, or remove the AIB/eAIB from the robot for any reason, please follow the procedures in this section.

CAUTION: Unless you need to replace a cable with a new cable, the Roxtec cable seal assembly should not be opened.

NOTE: If you only need to disconnect cables from the AIB/eAIB, you can do so by

just removing the cable entry housing cover, covered in this section. See Figure 9-4.
