System-Specific Circuitry Of The Booster Amplifier - Bosch Rexroth VT-MSFA1 Operating Instructions Manual

18/28 Bosch Rexroth AG
Assembly
Before installation note down the information on the name plates. If, after the
f
installation, name plates are no longer visible or legible, these data will be
quickly available to you at any time.
Ensure during the assembly of several modules that there is still enough
f
space for any subsequent removal of the booster amplifiers.
The installation position of the booster amplifier is vertical. It is assembled without
tools on a carrier rail TH35-7,5 according to EN 60715 (top hat rail). Foot latches
with spring pressure are provided for fixation of the module housing.
By snapping the housing of the VT-MSFA1 on a conductive assembly rail, the
earthing connection is established. This constitutes the HF earthing of the
VT-MSFA1 booster amplifier.
Engage the booster amplifier on the carrier rail. A foot latch (with spring pres-
f
sure) prevents loosening of the module housing from the carrier rail.
For loosening the module, push the foot latch downwards.

7.4.1 System-specific circuitry of the booster amplifier

All device connections (2 plug-in screw connectors, see chap. 7.6.4, 2-pole, wire
cross-section: 0.2 mm 2 to 2.5 mm
Rigid or flexible wires are possible.
Limitations with regard to line length and cable thickness are possible depend-
ing on the mating connectors used of the components to be connected. Lay all
lines (e. g. for supply, switching signals, valve solenoid, etc.) considering the
technical data (input resistance, current consumption) with regard to cable
thickness and length so that the operating data and working ranges (input
voltages, current consumption) are complied with.
