Fitting of additional terminals by the customer
Modify the device carefully and only in accordance with the safety notes
(see "Safety" section).
Ascertain additional terminal points, terminal type, quantity, cross-section and current
load.
Check whether type plate data is changed as a result of subsequently equipping
(cross-section, voltage, current, etc.).
Check whether enough space and fastening options are available for equipping.
