5.2.3.1 Control cabinet / terminal box
The TwinSAFE terminals must be installed in a control cabinet or terminal box with IP54 protection class
according to IEC 60529 as a minimum.
5.2.3.2 Installation on mounting rails
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!
Installation
Material damage due to improper installation
Pressing on the LED strip can damage the TwinSAFE component and impair the function of the LEDs.
• Do not press on the LED strip when pushing the TwinSAFE component against the mounting rail.
Instead, grasp the TwinSAFE component at the top and bottom edge or at the height of the orange tab
to slide it onto the mounting rail.
Fig. 6: Installation on the mounting rail
The bus couplers and bus terminals are attached to commercially available 35 mm mounting rails (DIN rail
according to EN 60715) by applying slight pressure:
1. First attach the fieldbus coupler to the mounting rail.
2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. To do this, plug the
components together with tongue and groove and push the terminals against the mounting rail until
the latch audibly engages on the mounting rail.
If you first snap the terminals onto the mounting rail and then push them next to each other without the
tongue and groove interlocking, no functional connection will be established! When correctly
assembled, no significant gap should be visible between the housings.
