Handling And Installation; Electrical Connections; The Five Safety Rules; Safe Operation - BONFIGLIOLI Active Cube Series Complement To Operating Instructions

 If you use the frequency inverter in combination with third-party products, you do so at your own
risk.
2.9.3

Handling and installation

 Do not commission any damaged or destroyed components.
 Prevent any mechanical overloading of the frequency inverter. Do not bend any components and
never change the isolation distances.
 Do not touch any electronic construction elements and contacts. The frequency inverter is
equipped with components which are sensitive to electrostatic energy and can be damaged if han-
dled improperly. Any use of damaged or destroyed components will endanger the machine/plant
safety and shall be considered as non-compliance with the applicable standards.
 Only install the frequency inverter in a suitable operating environment. The frequency inverter is
exclusively designed for installation in industrial environments.
 If seals are removed from the case, this can result in the warranty becoming null and void.
2.9.4

Electrical connections


The five safety rules must be complied with.

Never touch live terminals. In sizes 1 through 7, the DC-link may have dangerous voltage levels
up to 3 minutes after shutdown. In size 8, the DC-link may have dangerous voltage levels up to 8
minutes after shutdown.
 When performing any work on/with the frequency inverter, always comply with the applicable na-
tional and international regulations/laws on work on electrical equipment/plants of the country in
which the frequency inverter is used.
 The cables connected to the frequency inverters may not be subjected to high-voltage insulation
tests unless appropriate circuitry measures are taken before.
 Only connect the frequency inverter to suitable supply mains. The frequency inverter may be op-
erated in TN, TT and IT grid types. Precautions must be taken for operation in IT grids, see Chap-
ter 7 "Electrical installation". Operation in a corner-grounded TN grid shall not be permissible.
2.9.4.1

The five safety rules

When working on/in electrical plants, always follow the five safety rules:
1 Isolate
2 Secure to prevent restarting
3 Check isolation
4 Earth and short-circuit
5 Cover or shield neighboring live parts
2.9.5

Safe operation

 During operation of the frequency inverter, always comply with the applicable national and inter-
national regulations/laws on work on electrical equipment/plants.
 Before commissioning and the start of the operation, make sure to fix all covers and check the
terminals. Check the additional monitoring and protective devices according to the applicable na-
tional and international safety directives.
 During operation, all covers must be installed correctly, and all electrical cabinet doors must be
closed. During operation, never open the machine/plant.
 No connection work shall be carried out while power supply is on.
 The machine/plant holds high voltage levels during operation, is equipped with rotating parts
(fan) and has hot surfaces. Any unauthorized removal of covers, improper use, wrong installation
or operation may result in serious injuries or material damage.
 Some components, e.g. the heat sink or braking resistor, may be hot even some time after the
machine/plant was shut down. Don't touch any surfaces directly after shutdown. Wear safety
gloves where necessary.

The frequency inverter may hold dangerous voltage levels until the capacitor in the DC link is dis-
charged. After shutdown, wait for at least 3 minutes (sizes 1 through 7) and at least 8 minutes
