NSTALLATION INSTRUCTIONS
WARNING
Risk of electrical shock, fire, personal injury or death.
- Turn input 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. Other
mounting orientations require a reduction in output current.
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. Unused screw terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed.
The enclosure of the device provides a degree of ingress protection of IP20. The housing does not provide protection against
spilled liquids.
The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC 61010-2-201.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE
(Protective Earth) connection.
The device is suitable to be supplied from TN, TT or IT mains networks. The continuous voltage between the input terminals
and the PE potential must not exceed 300Vac.
The input can also be powered from a battery or a similar DC source. The continuous voltage between the supply voltage and
the PE/ground potential must not exceed 375Vdc.
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 6000m. Above 2000m a reduction in output current and over voltage category is
required.
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase
the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%,
the 5mm can be reduced to zero.
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 10A B- or C-Characteristic to avoid a nuisance
tripping of the circuit breaker.
