ABB VD4 Installation And Service Instructions Manual page 45

To prevent the cabling wires outside the circuit-breaker (carried out
by the customer) from accidentally coming into contact with moving
parts and therefore undergoing damage to the insulation, it is
recommended to fix the wires as shown in fig. 10a.
Before removing the operating mechanism cover to
access the terminal box, check that the circuit-breaker is
open and the closing spring discharged.
