DRIVE-CLiQ Hub Module External DME20
9.3.1
Description
The DRIVE-CLiQ Hub Module External DME20, just like the DRIVE-CLiQ Hub Module
DMC20, is only used to connect direct measuring systems for the feed axes and expansion
axes of the S120 Combi.
The component has degree of protection IP67.
Note
The DME20 should also be used if only one feed axis is coupled with a direct measuring
system.
A fixed topology applies when assigning the particular feed axis to a DRIVE-CLiQ interface
(see Section Topology rules for DRIVE-CLiQ (Page 121)) and this must be observed.

Safety instructions for DME20 DRIVE-CLiQ Hub Modules
NOTICE
Damage due to leaking plug connections
If IP67 protection is not ensured, water or dirt can enter and lead to material damage.
• All plug connectors must be correctly screwed into place and appropriately locked.
Note
Malfunctions due to soiled DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of soiled DRIVE
-CLiQ interfaces.
•
Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
Note
Function equipotential bonding for distributed DRIVE-CLiQ nodes
All components operated on the DRIVE
-CLiQ must be integrated into the equipotential
bonding concept.
They should preferably be connected by installing them on bare metal machine parts and
devices, whic
h are all bonded to one another in an equipotential manner.
Alternatively, equipotential bonding can be achieved by means of a conductor (at least
6
mm²), which should be routed parallel to the DRIVE-CLiQ where possible. This applies to
all distributed DRI
VE-CLiQ participants.
For the DME20 this also applies to the 24 V power supply.
