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 back-
ing plate.
For dimensional drawings/hole
pitch see table 2.2, figure 2.1 and
figure 2.2
The tapping area will provide you
with good, full-area contact.
2.
Mount the servocontroller vertically on the
backing plate.
Observe the mounting clear-
ances!
The contact area must be metalli-
cally bright.
3.
Mount the other components, such as
the mains filter, mains choke etc., on the
backing plate.
The cable between mains filter
and servocontroller may be max.
30 cm long.

NOTe: For all sizes of the ServoA 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 condi-
tions must be improved.
Air flow: min. 1.2 m/s

2.1 Notes for operation
!
Please be sure to avoid:
• penetration of damp into the device;
• aggressive or conductive substances in the immediate vicinity;
• drill chippings, screws or foreigh bodies dropping into the device;
• ventilation openings being covered over, as otherwise the device may be dam-
aged.
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 designated only for vertical installation in switch cabinets. The switch
cabinet must as a minimum provide IP4x protection.
ATTeNTION!
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. Max. pollution severity 2.
