Terminal box
Series G150/1
6.2.1 Conductor Connection
Select suitable conductors that do not exceed the permitted heating temperature within the
enclosure.
Ensure that conductors have the specified cross-sections.
Guide the conductor insulation so that it reaches the terminals.
Do not damage the conductor when stripping the insulation (e.g. by denting it).
Attach the core end sleeves properly.
If the system is equipped with all possible terminals and live conductors, and and the
maximum current load has been reached, ensure that the length of a conductor from the
screw connection to the terminal point does not exceed the diagonal planes of the
enclosure.
6.2.2 Protective Conductor Connection
Always connect the protective conductor.
Use cable lugs for external protective conductor connection.
Permanently install the protective conductor close to the enclosure.
Connect all uncoated, non-energised metal parts to the protective conductor system.
Neutral conductors have to be installed as live conductors.
6.2.3 Installation Conditions
Distances, creepage distances and clearances
When installing components, the creepage distances and clearances between the
individual components as well as between the components and the enclosure wall must
be sufficiently dimensioned. Observe the information from the manufacturer.
Check the creepage distances of the components and comply with them in accordance
with the specifications in the respective operating instructions.
The clearance distances, depending on the rated operational voltage of the fitted
terminals, must be complied with.
Observe the distance between the enclosure cover and connection screws of the built-in
components (with the conductor connected): at least the value of the required clearances.
DANGER! Danger due to significant heating inside the enclosure!
Non-compliance can result in damage to the device.
Select suitable conductors that do not exceed the permitted heating temperature
within the enclosure.
Pay attention to the specified cross-sections.
Attach the core end sleeves properly.
The necessary technical details/data on electric installation can be found in the following
documents:
"Technical data" chapter in these operating instructions
Documentation and data sheets provided by the terminal manufacturers
Documentation and data sheets of the installed devices
(e.g. for specifications on equipotential bonding, earthing)
