Connection of an external 24 V voltage supply

The PROFIBUS module has been designed to allow an external 24 V Power
Supply to be provided to the Profibus Module.
If this arrangement is required, it is necessary to make use of a 'Hybrid' Cable
which provides both communications and power supply cable cores, which is fed
into the PROFIBUS module through the module gland holes.
Recommended cable type :
PROFIBUS Cable (hybrid) : Siemens Type : 6ES7 194 -1LY10-0AA0-Z
Due to the larger cross section of this hybrid cable to standard PROFIBUS Cable, it
is recommended to use the following cable gland arrangement (not included with
PROFIBUS Module) :
a. Cable Gland M20 x 1.5 (Suggested Type : Lapp Group :
Part Nr : 53112630).
b. Gland adapter ring : M20x1.5 to M16x1.5 (Suggested type : Malux :
Part nr. : CA-740274)
This arrangement is required for each cable gland hole.
A +10 V to +24 V DC external power supply can be connected via the 11-way
terminal block, see Section 4.2.
