6.2 Power Module PM240-2; frame size FSA / FSB
6.2.3 Mounting / Connecting the power module
Take the boreholes for brake resistor and shielding plate into account
Power module, brake resistor and shielding plate have different hole patterns. WEISS GmbH recommends drilling
the boreholes for all three components during the installation. This way, further drilling, possible interferences due to
metal chips and mechanical loads are avoided during an eventual retrofitting.
1. Drill boreholes in the control cabinet depending on the dimensions of the power module used (see chapter 6.2.1
„Dimensions, hole patterns“ on page 56).
2. Drill boreholes for the brake resistor and the shielding plate according to the recommendation of WEISS GmbH.
3. Regard the required cooling and mounting clearances.
4. Screw on the power module

Cooling and mounting clearances for power modules
The following clearances must be observed between the components when mounting
1)
:
- Frame size FSA: 30 mm (1.18 inch)
- Frame size FSB: 40 mm (1.57 inch)
The following cooling clearances must be observed above and below the device:
- Frame sizes FSA and FSB: above 80 mm (3.15 inch),
- Frame sizes FSA and FSB: below 100 mm (3.93 inch),
The following cooling clearances must be observed in front of the device:
- Frame sizes FSA: 30 mm (1.18 inch)
- Frame sizes FSB: 30 mm (1.18 inch)
Devices which could restrict the cooling air flow may not be mounted in this area. It must be ensured that the cooling
air flow of the power modules is not blocked.
1)
The power modules can be mounted side by side without base components up to an ambient temperature of 40 °C.
In combination with base components and at ambient temperatures of 40 °C ... 55 °C, the specified lateral minimum clearances must be obser-
ved. Where combinations of different frame sizes are concerned, the largest of the two clearances shall apply.
