NOTICE
Strain on the power cable connector
The power cable is attached to / removed from the power supply using the knurled nut integrated in the plug. Avoid twisting
the plug once it is mounted. If high shock and vibration occurs, this stress must be absorbed by the power cable.
NOTICE
Restriction for maximum load
If the readers are operated permanently at full load and the digital inputs/outputs are loaded with the maximum total current
of 1.1 A, the maximum current consumption of a reader can reach 2 A. In this case, a maximum of one reader may be
connected per wide-range power supply unit.
The wide-range power supply unit (protection class I, degree of protection IP67) has four mounting holes for securing the
device.
Installation instructions
The power supply unit must be connected with the described connecting cables in the primary and secondary circuits. The
connectors at the power supply unit end may only be removed or inserted when no voltage is applied. The degree of
protection IP67 is only achieved with correctly connected and locked connectors. Adequate spacing around the power
supply unit should be provided to ensure free convection. The connection of the voltage supply must be made taking into
account the valid country-specific regulations. It must be possible to de-energize the power supply unit using a suitable
device outside the voltage supply. The device is connected with connectors "L" to phase and "N" to the neutral conductor of
the power network. The "PE" connector must be connected to the protective conductor (see dimensions and pin
assignment). The power supply unit may only be operated with a connected protective conductor. The power supply unit is
maintenance-free and contains no parts to be changed by the user. The power derating when operating at an ambient
temperature of above 50 °C must be ensured by the user. The base area of the power supply unit is screwed onto the
mounting plate or mounting wall using the four mounting holes (e.g. screw and washer M5). Optimum cooling by natural
convection must be assured at the mounting location. When used where CSA C22.2 No 107.1-01 applies a separating
element must be provided for the output circuit.
Grounding connection
For reasons of EMC, the device should also be grounded via the grounding connection
①
primary input (PE) . Ensure that this connection is as short as possible and has a cable cross-section of at least 10 mm².
This will ensure that any faults occurring on the shielding can be dissipated as well as possible.
