PIM90.241
PIANO-Series
PRODUCT DESCRIPTION
The PIANO series units are extraordinarily compact
industrial grade DIN-rail power supplies that focus on
the essential features needed in today’s industrial
applications. The excellent cost/performance ratio
presents many new and exciting opportunities without
compromising quality or reliability.
The mechanically robust housing is made of a highgrade, reinforced molded material, which permits the
units to be used in surrounding temperatures up to
+70°C.
The PIM90.241 is equipped with push-in terminals,
which are optimized for automated wiring.
The unit is designed as “Class of Protection” II unit and
fulfills the safety and EMC requirements without an
input PE connection. This saves wiring costs.

TERMINOLOGY AND ABREVIATIONS
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. To be defined, value or description will follow later.
AC 230V A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
50Hz vs. 60Hz As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz mains
frequency. AC 120V parameters are valid for 60Hz mains frequency.

2. INSTALLATION INSTRUCTIONS
WARNING
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not modify or repair the unit.
- Do not open the unit as high voltages are present inside.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Obey the following installation instructions:
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of the device.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are
designed for a minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient
temperatures up to +60°C and 90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire
enter the terminal connection.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost allowed.
The enclosure of the device provides a degree of protection of IP20.
The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC
60664-1.
The device is designed as “Class of Protection” II equipment according to IEC 61140.
The device is suitable to be supplied from TN-, TT- and IT mains networks. The voltage between the L or N terminal
and the PE terminal must not exceed 300Vac continuously.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not
cover ventilation grid!
The device is designed for altitudes up to 5000m (16400ft). See additional requirements in this document for use above
2000m (6560ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 0mm left and right side.
Increase the 0mm to 15mm in case the adjacent device is a heat source.
The device is designed, tested and approved for branch circuits up to 32A (IEC) and 30A (UL) without additional
protection device. If an external fuse is utilized, do not use circuit breakers smaller than 6A B- or 4A C-Characteristic to
avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the same as the ambient
or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Risk of electrical shock, fire, personal injury or death.

4. DC-INPUT
Do not operate this power supply with DC-input voltage.
5. INPUT INRUSH CURRENT
A NTC limits the input inrush current after turn-on of the input voltage. The inrush current is input voltage and
ambient temperature dependent. The output load has no impact on the inrush current value.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
