The modules of the SIMODRIVE 611 drive converter system can also be ar-
ranged in two tiers one above the other or next to each other.
The distance between the rows of modules may not be less than 200 mm to
ensure unrestricted cooling. In this case it must be ensured that the cooling air
for the upper lineup does not exceed 40 _C – or with derating does not reach
55 _C. Otherwise, measures must be taken, for example an air baffle plate must
be used or offset mounting, see Fig 9-8. As a result of the equipment bus cable,
dependent on the design, the maximum clearance is specified
When arranging the cable ducts that may be required for the wiring it must be
ensured that the required minimum clearance to the SIMODRIVE 611 converter
system is not fallen below.
The modules with the higher power ratings – as well as the infeed module –
must be located in the upper row of modules.
The maximum expansion phase of a drive group is limited by the power rating
of the infeed module. Only one equipment bus extension is permissible: Either
to the left, e.g. for a second tier; or to the right, e.g. to bypass a cubicle panel.
For the SIMODRIVE 611 drive converter system, for a two–tier equipment con-
figuration, a connecting cable is required for the equipment and drive bus.
In the two–tier equipment configuration, the DC link is connected using
parallel cables (max. length, 5 m; in conjunction with
SIMODRIVE POSMO SI/CD/CA, the guidelines correspond to the User Manual
SIMODRIVE POSMO SI/CD/CA).
The required cable cross-section of the connecting cable for the downstream
modules can be obtained from the dimension drawing in Fig. 12-60. The three
cables should be tied together. These cables are not included with the equip-
ment.
The dimensions, specified in the diagram 9-7 apply for the DC link connection of
components that are separately located next to each other, e.g. extending over
several electrical cabinets.
Adapter terminals are available to connect the DC link.
The DC link voltage can be connected further using these adapter terminals,
e.g. to connect the DC link for two–tier configurations.
The following adapter terminals are available (refer to Fig. 9-7):
S
Package with two double terminals 50 mm
(to 100 A also for a module width of 300 mm)
(Order No.: 6SN1161–1AA01–0BA0)
S
Package with two double terminals 95 mm
(Order No.: 6SN1161–1AA01–0AA0)
Danger
Notice! Order No.: 6SN1161–1AA01–0AA0 Do not use for
module widths 50 – 200 mm. Danger of death because the contact safety is
endangered!
