Electrical installation
There are two types of installation methods:
• Pipeline installation:
If the enclosure is complete with factory installed entry hardware, proceed to chapter 6.2.2.
• Cable installation:
If the enclosure does not include factory installed entry hardware, select the appropriate
supports or cable glands from the "Accessories and spare parts" chapter and install them
as follows.
Installation of approved conduit hubs or cable glands
CAUTION! Field-installed openings! Drilling, milling or sanding these enclosures is
not recommended!
Non-compliance may result in serious or even fatal injuries.
 For field-installed openings, use a hand punch or pneumatic type punch.
All unused enclosure openings must be closed using approved stopping plugs with
standard locknuts.
6.2.2 Connecting Conductors
 Select suitable conductors that do not exceed the permissible 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.
There is an increased danger of heating if the terminal box is equipped with the maximum
number of terminals and conductors. This is also the case if it is loaded with the
maximum permissible current.
 Ensure that the length of a conductor does not exceed the length of the enclosure
diagonal. When doing so, the conductor is measured from the screw connection to the
clamping unit.
 Tighten all terminal blocks to the tightening torque values specified in table
(see chapter 6.2.3).
 Keep wires separated between different voltage systems.
 Ensure that the earthing conductor is connected between the "increased safety" terminals
on the metal plate or locknut and the earthing rail.
