4 Mounting and connecting the hardware
4.1 Safety notes
4.2 Basic information about mounting
Mounting location The controller has IP20 protection and is installed in charging stations for electric vehicles.
DIN rail The controller is mounted on a 35 mm standard DIN rail.
FE connection Functional ground must be connected via the power supply. The contacts are directly con -
nected to the potential bridge and FE springs on the bottom of the housing. The controller
is grounded when it is snapped onto a grounded DIN rail. Functional ground is only used to
discharge interference.
End bracket Mount end brackets on both sides of the controller. The end brackets ensure that the con -
troller is correctly installed. End brackets fix the controller on both sides and keep it from
moving from side to side on the DIN rail. Phoenix Contact recommends using CLIPFIX 35-
5 end brackets (Order No. 3022276).
Mounting position Mount the controller horizontally (see Figure 4 - 1 on page 40 ). The temperature range spec -
ified in Section 9.2, “Technical data” is only guaranteed if the controller is mounted in this
position.
NOTE: Electrostatic discharge
The device contains components that may be damaged or destroyed by electrostatic dis -
charge. When handling the device, observe the necessary safety precautions against
electrostatic discharge (ESD) in accordance with EN 61340-5-1 and IEC 61340-5-1.
NOTE:
• Ground the controller via the FE connection of the supply plug.
The controller is also grounded automatically when snapped onto a grounded 35 mm
standard DIN rail.
NOTE:
• Before any work on the device, always switch off the supply voltage and ensure it
cannot be switched on again.
