Installation on mounting rails

Only work on TwinSAFE components when they are de-energized
The Bus Terminal system is live. Set the Bus Terminal system to a safe, de-energized state before you
start mounting, dismounting or wiring the TwinSAFE components.
If you work on the TwinSAFE components while the Bus Terminal system is live, you may be injured by
electric shock. In addition, the device may be damaged.
Assembly
Fig. 7: Installation on the mounting rail
The EtherCAT Couplers and TwinSAFE Terminals are snapped onto standard 35 mm mounting rails by
applying slight pressure. The mounting rails are top-hat rails according to EN 60715. Mount the components
in the following sequence:
1. Plug the EtherCAT coupler onto the mounting rail.
2. Plug the TwinSAFE terminals together with tongue and groove.
3. ush the TwinSAFE terminals against the mounting rail until the latch audibly engages on the mounting
rail.
Ensure functional component connection
Adhere to the described assembly sequence. First plug the TwinSAFE terminals together with
tongue and groove. Only push the TwinSAFE terminals onto the mounting rail after they have been
plugged together.
If you first snap the TwinSAFE 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 mounted, no significant gap should be visible between the housings.
