2. Installation
A sufficiently strong DIN-rail has to be provided. The correct mounting position for optimal cooling performance must be
observed. Above and below the TSP-BFM24 a minimum free space of 80mm [3.15in] is required and on each side of the TSP-
BFM24 a minimum space of 50mm [1.97in] is required which allows air convection. The air temperature measured 10mm
[0.39in] below the device must not exceed the specified values in the data sheet. Observe power derating above ambient
temperatures of 40°C as specified for the TSP power supplies.
2.1 Assembly
To fix unit on the DIN-rail, hook top part of clip on DIN-rail, push down and inward until you hear a clipping sound.
To remove the unit, pull the latch of the clip with the aid of an insulated flat head screwdriver. When clip has cleared bottom DIN
rail remove the screwdriver from recess. Lift the unit off DIN-rail.
Wall mounting or chassis mounting can be achieved by use of optional mounting bracket TSP-WMK01 (1 bracket, see Fig. 3.1).
Remove the DIN-clips by removing the screw and place the mounting brackets in the same place as the DIN-clips. Use the
countersink screws, which are included with the wall mounting kit (1 countersink screw with TSP-WMK01) to fix the mounting
brackets on the TSP-BFM24 (tightening torque 0.8-0.9Nm).
2.2 Connecting cable
Only qualified personnel may carry out the installation.
The device is equipped with COMBICON connector and
COMBICON plug connectors (Signals). This reliable and easy-to-assemble connection method enables a fast connection of the
device.
2.2.1 Input
(Fig. 3.1
Î
Connector J1, pin 1, pin 2, pin 3, pin 4 & pin 5):
The connection is made by using the –Vin and +Vin connections (see Fig. 3.1
Î
Connector J1, pin 1, pin 2, pin 3 and pin 4) as
well as protective earth (see Fig. 3.1
Î
Connector J1, pin 5) and has to be carried out in accordance with the local regulations.
Sufficiently dimensioned wiring has to be ensured (see chapter 2.2.1.1) or has to be separately protected.
To achieve a reliable and shockproof connection strip the connecting ends according chapter 2.2.1.1. If flexible wires are used
the wires have to be terminated. (e.g. by using ferrules)

2.2.2 Signalling
(Fig. 3.1
Î
Connector J2, pin 3, pin 4, pin 5 & pin 6):
The output “Active” is for enabling monitoring of the functions if the TSP-BFM24 is in operation. This signal is detected by
measuring the input voltage direct at the input pins and is provided by an open collector opto coupler which can handle 10mA in
maximum (see also Fig 1.1 and Fig. 3.1
Î
connector J2, pin 3 & pin 4). The output “Ready” is providing the signal if the TSP-
BFM24 is ready to provide the current (see Fig. 3.1
Î
Connector J2, pin 5 & pin 6). The “Ready” signal is provided by an open
collector opto coupler which can handle 28Vdc/10mA. It is detected by measuring the TSP-BFM24 voltage level direct at the
capacitors (see Fig. 1.1).
2.2.2.1 Status LED:
The Status LED is a two colour LED which indicates the status of the TSP-BFM24 module and enables visual evaluation of the
function locally in the control cabinet. Status LED green – normal operation, TSP-BFM24 is ready to provide a current of 25A
max.. Status LED red – input voltage on the TSP-BFM24 is lower as the adjusted threshold level. Status LED is changing from
green to red – TSP power supply is charging the TSP-BFM24 module. Status LED green pulsing – TSP-BFM is providing output
current, discharging of TSP-BFM24.
3. Function
3.1 Inhibit:
The TSP-BFM24 unit provides an Inhibit function by use of pin 1 & pin 2 at connector J2 (see Fig. 3.1) to control the TSP-
BFM24 module. To switch off the TSP-BFM24 a voltage level between 5Vdc and 28Vdc has to be applied on Connector J2 pin 1
(Inhibit GND) and Connector J2, pin 2 (I). At open connection or a voltage level between 0Vdc and 1Vdc between J2 pin
1 (Inhibit GND) and pin 2 (I) the device is ready to provide the output current for the requested buffer time.
