Mechanical Installation

D Selecting the Installation Site
Maintain an ambient temperature of 0 to 50 _C. Don't forget to allow for other heat sources
in the vicinity. Remember that if instruments are stacked on top of each other with little or no
gap between them, additional heat will be generated. Front and rear sides of the controller
must be easily accessible.
D Panel mounting
The SIPART DR24 is installed either in single panel cut--outs or in open tiers (see figure
1--42, page 94 and 1--43, page 94 for dimensioned drawing).
- The upper edge of the panel cut--out must be left unpainted to ensure good interference
suppression of the controller even at high frequencies. A good HF ground connection is
established by the contact spring protruding from the top of the SIPART DR24.
- If necessary: Slide the self--adhesive gasket ring for sealing the front frame/front panel
over the body and adhere onto the reck of the body (see chapter 5.2, page 173, item
2.6).
- Insert SIPART DR24 into the panel cut--out or open tier from the front and fit the two
clamps provided to the controller unit from the rear so that they snap into the cut--outs in
the housing.
- Align SIPART DR24 and do not tighten the locking screws too tight. The tightening range
is 0 to 40 mm.

Electrical Connection

The layout of the connecting elements is shown in figure 2-1, page 109.
!
D PE conductor connection
Connect the PE conductor to the ground screw (see figure 2-1, page 109) on the back of the
controller. When connecting to 115 or 230 V AC mains supply, the PE conductor can also be
connected through the three--pin plug (see figure 2-1, page 109). The controller's ground
connection may also be connected with the PE conductor (grounded extra low voltages).
