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
power 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 power
supply. The device is connected the with connectors "L" to phase and "N" to the directly
earthed conductor. 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 in the area of applicability of CSA C22.2 No 107.1-01 a
separating element must be provided for the output circuit.
Degree of protection
The wide-range power supply unit for SIMATIC RF systems meets degree of protection
IP67.
● Dust-tight: No ingress of dust
● Protected against harm from temporary submersion in water: Water must not enter in
amounts that can cause damage, if the housing is immersed in water 1 m deep for 30
minutes.
All information applies only when connected and locked. The assignment of degrees of
protection is subject to standardized test methods. If no secondary cables are connected,
close the secondary sockets with a protective cap.
