(1) Connection capacities actually available for each machine. These are defined according to the connection terminal size, the electrical box access opening dimensions
and the available space inside the electrical box.
(2) Selection simulation result considering the hypotheses indicated.
(3) If the maximum calculated section is for an XLPE cable type, this means that a selection based on a PVC cable type can exceed the connection capacity actually
available. Special attention must be given to selection.
The protection against direct contact at the electrical connection point is compatible with the addition of terminals extension. The installer must determine whether
these are necessary based on the cable sizing calculation.
6.4 - Power cable access routing
The power cables for devices in the range are routed into the electrical box from underneath the unit.
A removable aluminium plate on the base of the electrical cabinet provides access for the power cables.
It is important to check that the power cable bend radius is compatible with the connection space available inside the electrical
cabinet.
Refer to the certified dimensional drawing for the unit.
Connection expansion box
This accessory is used to strip the power cable before it is routed inside the unit's electrical cabinet, and must be used when the
cable bend radius is not compatible with the space available inside the electrical cabinet. The "connection expansion box" accessory
provides mechanical protection for the stripped cable before it is routed inside the electrical cabinet.
It is recommended to use this accessory in the following cases:
Unit placed on the ground and the use of steel wired armoured (SWA) cables.
Unit placed on the ground and use of a rigid power cable with a section > 250 mm
