The subrack must be able to discharge hot air:
 The discharged air may not be restricted by mounted components
 When mounting equipment or other components, a minimum clearance
of 60 mm must be maintained above and below the subrack
If the subrack is mounted in a cabinet, the cabinet must have air ventilation
slots. If the cabinet is enclosed, the subrack must be force-ventilated (an
SR6V must be used).
If two subracks are mounted one on top of the other, there must be a
minimum 120 mm clearance between the two subracks, whereby the upper
subrack must be separated from the lower subrack by an air deflection plate.
 The subrack must be connected to the grounding rail via the connecting
studs through a min. 6 mm² cable which should be kept as short as
possible.
Potential bonding using the PE pin of line connector X1 is not sufficient!
 All of the cabinets associated with networked SIMADYN D drives must be
connected with one another through a potential bonding conductor
having a minimum cross-section of 16 mm².
 Empty slots must be provided with SIMADYN D slot covers (SR81, SR82,
SR83).
 All modules must be tightly screwed into the subrack.
 No undamped contactors may be used in a cabinet together with
SIMADYN D.
 If undamped contactors are mounted in a cabinet next to SIMADYN D,
the cabinets must have a metal partition between them.
 The protective contactor is connected at the subrack and at the power
supply. Both components must be at protective conductor potential.
 Before removing the power supply, the connecting cables must be
disconnected. The connecting cables must first be disconnected from the
supply so that they are in a no-voltage condition!
 The screens of screened cables must be directly connected to the
grounding- or screen rails and fed to the interface modules, still
screened.
