Disclaimer:
Before installing and using the TSP unit read the safety and installation instructions provided with the unit.

1. Mechanical Mounting

To fix unit on the DIN-rail, hook top part of clip on DIN-rail, push down- (see Fig 2.1) and inwards (see Fig 2.2) 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 (see Fig 2.3). When clip has cleared bottom DIN
rail remove the screwdriver from recess. Lift the unit off DIN-rail. See Fig 2.4.
Wall mounting or chassis mounting can be achieved by use of optional mounting brackets TSP-WMK01 (1 bracket) for TSP 070, TSP 090,
TSP 140 & TSP 180 or TSP-WMK02 (2 brackets) for TSP 360 & TSP 600 – see datasheet page 9. 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 and 2 countersink screws with TSP-WMK02) to fix the mounting brackets on the TSP
power supply (tightening torque 0.8-0.9Nm).

2. Electrical Connections

2.1 Wire and Cable Requirements
To achieve a reliable and shockproof connection strip the connecting ends according the installation manual. If flexible wires are used the wires
have to be terminated. (e.g. by using ferrules).
2.2 Connecting cables
The devices are equipped with COMBICON plug connectors (TSP 070-112, TSP 090-1xx, TSP 140-112, TSP 180-1xx and TSP 360-1xx) or
COMBICON connector (TSP 600-1xx). This reliable and easy-to-assemble connection method enables a fast connection of devices and a
visible isolation of the electrical connection if necessary.
(Fig. 4.1, Fig 4.2, Fig 4.3 and Fig. 4.4  Connector J1):
2.2.1 Input
(Fig. 4.1, Fig 4.2, Fig 4.3 and Fig. 4.4  Connector J2):
2.2.2 Output
All output terminals should be connected to the load.
2.2.3 Floating contacts
(Fig. 4.1, Fig 4.2, Fig 4.3 Connector J2; Fig. 4.4 Connector J5):
For heavily inductive loads such as relay, a suitable protection circuit (e.g. damping diode) is necessary.
2.2.4 Active signal output
(Fig. 4.1, Fig 4.2, Fig 4.3 Connector J2; Fig. 4.4 Connector J5):
3. Function
3.1 Signalling
The two DC-OK outputs are for enabling monitoring of the functions of the power supply. A floating signal contact and an active DC-OK signal
are available.
The DC-OK LED also enables a visual evaluation of the function of the power supply directly on site: green – normal operation or red – output
failure if input is still present.
The DC-OK signal is decoupled from the power output. It is thus not possible for parallel-switched devices to provide external supply. The DC-
OK signal can be directly connected to a logic input for evaluation.
Signal loop: The active DC-OK and floating contact DC-Ok can be easily combined.
Example: Monitoring of two devices.
Use the active signal output of device 1 and loop in the floating signal output of device 2. In the event of malfunctioning a common alarm is
available. Up to 5 units can be looped in. This signal combination saves wiring costs and logic inputs.
3.2 Output characteristic curve:
In the case that the ambient temperatures is not higher than +40°C, the device can continuousely supply Iout max (see datasheet). In the
event of a higher load, the operating point follows the U/I charateristic curve by use of overcurrent protection. The output current is limited at
Iout max. by use of a constant current characteristic with automatic restart if the short circuit or over load condition has been removed.
The U/I characteristic curve ensures that heavily capacitive loads can be fed without problems.
3.3 Thermal behaviour:
The device should not be operated at higher loads than indicated on the derating graphs presented in datasheet. The device does switch off at
thermal overload. After sufficent cooling the device will switch on again.
3.4 Parallel operation:
Maximum 5 devices ot he same type can be connected in parallel to enable increased output power. For n parallel connected devices the
output current can be increased to n x Imax. Parallel connection to increase efficiency is used for the expansion of existing systems. It is
advisable to use parallel connection if the power supply does not cover the current requirment of the most powerful consumer. Otherwise the
consumers should be spread among individual devices independent of one another.
To provide a proper and relaible start-up the jumper at connector J4 has to be set (see Fig. 4.1, Fig. 4.2, Fig. 4.3 & Fig. 4.4). If the jumper is set
between pin 1 and pin 2 of connector J4 the unit is in normal mode. If the jumper is set between pin 2 and pin 3 on connector J4 the unit can be
paralleled. At delivery this jumper is set for normal operation (between pin 1 and pin 2 of connector J4).
If the output voltage is adjusted, a uniform distribution of power is guaranteed by setting all parallel operated power supplies to exactly the
same output voltage. To ensure symmetrical distribution of power, we recommend designing all cable from the power supply as busbar of the
same length and with the same conductor cross section. The system makes it advisable to install a protective circuit at the output of each
device when more than two power supplies are connected in parallel (e.g. decoupling diode or DC fuse). This prevents high reverse feed
currents in the event of a secondary device fault.
