Installation on mounting rails

WARNING

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!

Mounting

Fig. 5: 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. Join the compo-

nents with slot and key and push the terminals against the mounting rail, until the lock clicks onto the

mounting rail.

If the terminals are clipped onto the mounting rail first and then pushed together without slot and key,

the connection will not be operational! When correctly assembled, no significant gap should be visible

between the housings.

Fastening of mounting rails

The locking mechanism of the terminals and couplers protrudes into the profile of the mounting rail.

When installing the components, make sure that the locking mechanism doesn't come into conflict

with the fixing bolts of the mounting rail. For fastening mounting rails with a height of 7.5 mm under

the terminals and couplers, use flat fastening components such as countersunk head screws or

blind rivets.
