2.1 Notes for operation
!
Please strictly avoid ...
•
penetration of damp into the device;
•
aggressive or conductive substances in the immediate vicinity;
•
drill chippings, screws or foreign bodies dropping into the device;
•
ventilation openings being covered over, as otherwise the device may
be damaged.
Note the following points:
•
Cooling air must be able to flow through the device without restriction.
•
For mounting in switch cabinets with convection (= heat loss is discharged to the
outside via the cabinet walls), always fit an internal air circulation fan.
•
The backing plate must be well grounded.
•
The device is designed only for vertical installation in switch cabinets. The switch
cabinet must as a minimum provide IP4x protection.
!
ATTENTION!
According to EN ISO 13849-2 the switch cabinet must have IP54
protection or higher when using the STO (Safe Torque OFF) safety function.
•
To attain the best result for EMC-compatible installation you should use a
chromated or galvanized backing plate. If backing plates are varnished, remove the
coating from the contact area. The devices themselves have an aluminium back
panel.
•
Maximum pollution severity 2.
Further information on environmental conditions can be found in the appendix.

Step
Action
Comment
1.
Mark out the position of the tapped holes on
the backing plate.
Cut a tap for each fixing screw in the backing
plate.
Dimensional drawings/hole spac-
ing - see table 2.2, Fig. 2.1 and
Fig. 2.2
The tapping area will provide you
with good, full-area contact.
2.
Mount the servo drive
vertically
on the
backing plate.
Observe the mounting clearances!
The contact area must be metallic
bright.
3.
Mount the other components, such as the
mains filter, mains choke etc., on the backing
plate.
The cable between mains filter and
servo drive may be maximum
30 cm long.
4.
Continue with the electrical installation in
section 3.
Table 2.1 Mechanical installation
NOTE:
For all sizes of the MSD Servo Drive
Compact forced cooling by external air flow
is necessary. The air must be able to flow
unhindered through the device. If a temperature
cut-out occurs, the cooling conditions must be
improved.
Air flow: minimum 1.2 m/s
