Installation and mounting

5.1

Connection method

The connection is made using one or two joint blocks. One or more fixing screws are
tightened with a conventional spanner or ring spanner. A secure joint is thus achieved in a
short time.
In individual steps: The first screw-head shears off when the defined torque is reached. The
second screw-head underneath releases the joint connection. When the trunking unit (joint
block) is used again, the second head must be tightened with a torque wrench to a defined
torque of 120+10 Nm.
The joint block is fixed to the trunking unit. It does not compensate for the length expansion
of the trunking unit. Expansion compensation must therefore be configured in accordance
with the applicable configuring rules, see "Configuring expansion compensation and fixed
point".

The minimum dimension 0.10 m applies for all degrees of protection. When configuring
expansion compensation and fire barriers, the distance to the ceiling at these points is
correspondingly less, see Chapter "LXA/LXC busbar trunking systems" – Dimension drawings.
