2. GENERAL CHARACTERISTICS
TRS-09a is a supporting power supply for the TRS System which supplies stabilized
direct voltage 11.5V. It can work in two modes: as a controlled supply (switched on with
external voltage 7 ÷ 12V) or a non-controlled supply. The configuration is selected by means of
a link. Current efficiency is 200 mA. The supply is resistant to output voltage short circuit. The
device is located in a casing that completely protects it against dust or low pressure streams of
water.

User manual - POWER SUPPLY TRS-09a
This is a class A unit. In housing or a similar area it can cause radio
frequency interference. In such cases the user can be requested to use
appropriate preventive measures.
Detailed informations about installation of TRS system user can find in:
“User manual for Temperature and Humidity Recording System”.
4. DEVICE INSTALLATION
The unit has been designed and manufactured in a way assuring a high level of user
safety and resistance to interference occurring in a typical industrial environment. In order to
take full advantage of these characteristics installation of the unit must be conducted correctly
and according to the local regulations.
- Read the basic safety requirements on page 3 prior to starting the installation.
- Ensure that the power supply network voltage corresponds to the nominal
voltage stated on the unit’s identification label.
- The load must correspond to the requirements listed in the technical data.
- All installation works must be conducted with a disconnected power supply.
- Protecting the power supply clamps against unauthorized persons must be
taken into consideration.
4.1. UNPACKING
After removing the unit from the protective packaging, check for transportation damage.
Any transportation damage must be immediately reported to the carrier. Also, write down the
unit serial number on the housing and report the damage to the manufacturer.
Attached with the unit please find:
- warranty,
- user’s manual for TRS-09a unit (device)
4.2. ASSEMBLY
- Disconnect the power supply prior to starting assembly.
- Check the correctness of the performed connections prior to switching the unit on.
To install the device prepare pinholes accordingly to Figure 4.1. Back side of the
case (with mounting holes) should be mounted to a wall using screws.

4.3. CONNECTION METHOD
Caution
- Installation should be conducted by qualified personnel . During installation all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC
regulations.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this an external time-delay cut-out fuse with minimal possible nominal
current value must be used (recommended bipolar, max. 2A) and a power supply
circuit-breaker located near the unit. In the case of using a monopolar fuse it must
be mounted on the phase cable (L).
- The power supply network cable diameter must be selected in such a way that in
the case of a short circuit of the cable from the side of the unit the cable shall be
protected against destruction with an electrical installation fuse.
- Wiring must meet appropriate standards and local regulations and laws.
- In order to secure against accidental short circuit the connection cables must be
terminated with appropriate insulated cable tips.
- Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.

- In the case of the unit being fitted with separable clamps they should be inserted
into appropriate connectors in the unit, even if they are not used for any
connections.
- Unused clamps (marked as n.c.) must not be used for connecting any connecting
cables (e.g. as bridges), because this can cause damage to the equipment or
electric shock.
- If the unit is equipped with housing, covers and sealing packing, protecting
against water intrusion, pay special attention to their correct tightening or clamping.
In the case of any doubt consider using additional preventive measures (covers,
roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric
shock.
- After the installation is completed do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.
Due to possible significant interference in industrial installations appropriate measures
assuring correct operation of the unit must be applied. To avoid the unit of improper
indications keep recommendations listed below.
-Avoid common (parallel) leading of signal cables and transmission cables together with
power supply cables and cables controlling induction loads (e.g. contactors). Such cables
should cross at a right angle.
-Contactor coils and induction loads should be equipped with anti-interference protection
systems, e.g. RC-type.
-Use of screened signal cables is recommended. Signal cable screens should be
connected to the earthing only at one of the ends of the screened cable.
-In the case of magnetically induced interference the use of twisted couples of signal cables
(so-called “spirals”) is recommended. The spiral (best if shielded) must be used with RS-
4 5 serial transmission connections.
-In the case of interference from the power supply side the use of appropriate anti-
interference filters is recommended. Bear in mind that the connection between the filter
and the unit should be as short as possible and the metal housing of the filter must be
connected to the earthing with largest possible surface. The cables connected to the filter
output must not run in parallel with cables with interference (e.g. circuits controlling relays
or contactors).
Connections of power supply voltage and measurement signals are executed using the
screw connections inside of the unit’s housing (Figure 4.2 - 4.4).

Serial connection of power supply modules TRS-09a (while power output of one module
drives control input of the next one, Figure 4.6), allows turn off all modules connected to the
network at the same time. When power supply of first TRS-09a module is turned off, then
following power supply modules will be turned off sequentially.

4.4. MAINTENANCE
The unit does not have any internal replaceable or adjustable components available to the
user. Pay attention to the ambient temperature in the room where the unit is operating.
Excessively high temperatures cause faster ageing of the internal components and shorten the
fault-free time of unit operation.
In cases where the unit gets dirty do not clean with solvents. For cleaning use warm water with
small amount of detergent or in the case of more significant contamination ethyl or isopropyl
alcohol.
Using any other agents can cause permanent damage to the housing.
Product marked with this symbol should not be placed in municipal waste. Please
check local regulations for disposal and electronic products.
5. SELECTION OF OPERATION MODE
The selection of operation mode can be done by proper jumper settings (see Figure 5.1):
•externa y contro ed mode : {J1} open , {J2} open or short
This configuration allows to remote control of the module using it's control input (voltage
7÷12V connected to { ctrl } terminal). If control input is not connected, or it's voltage is to low,
module output voltage is turned off - voltage between terminals { +12V out } and { GND } will
drop to 0V.
•Stand a one mode : {J1} short, {J2} open
This configuration allows stand alone mode of module operation. Module is independent
of external signal { ctrl }. Power supply module is permanently turned on - voltage between
terminals { +12V out } and { GND } is about 11.5 V.
