2 Product overview
2.1 Introduction
Fig.1: KL9570
The KL9570 Bus Terminal contains high-performance capacitors for stabilizing supply voltages. It can be
used in conjunction with the stepper motor terminals KL2531 and KL2541 and the DC motor terminals
KL2532 and KL2552.
Low internal resistance and high pulse current capability enable good buffering in parallel with a power
supply unit. Return currents are stored, particularly in the context of drive applications, thereby preventing
overvoltages. If the recovery energy exceeds the capacity of the capacitors, energy can be dissipated via an
external ballast resistor.
Functioning
• The KL9570 monitors the voltage between terminal points 2(+UIN) and 6(-UIN).
• When this voltage reaches 55V, the KL9570 establishes a connection between terminal points 5 and
6.
• If the voltage between terminal points 2 and 6 falls below 52V, the KL9570 disconnects terminal points
5 and 6 from each other again.
The switch-on threshold of 55V in conjunction with the switch-off threshold results in a hysteresis of 3V.
If you connect a brake resistor (typically10Ω) between terminal points 1(+Rext) and 5(-Rext),
it dissipates the surplus energy when the KL9570 connects terminal points 5 and 6.

3 Mounting and wiring
3.1 Installation on mounting rails
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation,
disassembly or wiring of the Bus Terminals!
Assembly
Fig.2: Attaching on mounting rail
The Bus Coupler and Bus Terminals are attached to commercially available 35mm mounting rails (DIN rails
according to EN60715) by applying slight pressure:
1. First attach the Fieldbus Coupler to the mounting rail.
2. The Bus Terminals are now attached on the right-hand side of the Fieldbus Coupler. Join the compo-
nents with tongue and groove and push the terminals against the mounting rail, until the lock clicks
onto the mounting rail.
If the Terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.
Note
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting
rail. At the installation, the locking mechanism of the components must not come into con-
flict with the fixing bolts of the mounting rail. To mount the mounting rails with a height of
7.5mm under the terminals and couplers, you should use flat mounting connections (e.g.
countersunk screws or blind rivets).
