ATTENTION

IT NEUTRAL POINT CONNECTION : In the event of use on a 3-phase network with a voltage greater

than 460V ±10 % with an isolated or high-impedance system (IT), the internal EMC filter capacitors

which are connected to ground must be disconnected. Consult Schneider product support who are the

only people qualified to perform this operation.

When the speed controller is powered up, the power components and some of the control components

are connected to the line supply. It is extremely dangerous to touch them. The speed controller cover

must be kept closed.

ATTENTION

After the ALTIVAR has been switched off and the green LED has gone out, wait for 3 minutes before

working on the equipment. This is the time required for the capacitors to discharge.

The motor can be stopped during operation by inhibiting start commands or the speed reference while

the speed controller remains powered up. If personnel safety requires prevention of sudden restarts,

this electronic locking system is not sufficient : fit a device to remove the power circuit.

The speed controller is fitted with safety devices which, in the event of a fault, can shut down the speed

controller and consequently the motor. The motor itself may be stopped by a mechanical blockage.

Finally, voltage variations, especially line supply failures, can also cause shutdowns.

NOTE

If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain

machines or installations, especially those which must conform to safety regulations.

In this case the user must take precautions against the possibility of restarts, in particular by using a

low speed detector to cut off power to the speed controller if the motor performs an unprogrammed

shutdown.

The design of equipment must conform to the requirements of IEC standards.

In general, the speed controller power supply must be disconnected before any operation on either the

electrical or mechanical parts of the installation or machine.

The products and equipment described in this document may be changed or modified at any time,

either from a technical point of view or in the way they are operated. Their description can in no way

be considered contractual.

Warning

The Altivar 58 must be considered as a component : it is neither a machine nor a device ready for use in ac-

cordance with European directives (machinery directive and electromagnetic compatibility directive). It is the

responsibility of the end user to ensure that the machine meets these standards.

The speed controller must be installed and set up in accordance with both international and national

standards. Bringing the device into conformity is the responsibility of the systems integrator who must

observe the EMC directive among others within the European Union.

The specifications contained in this document must be applied in order to comply with the essential requi-

rements of the EMC directive.

Preliminary Recommendations

Delivery

Check that the speed controller reference printed on the label is the same as that on the delivery note

corresponding to the purchase order.

Remove the Altivar 58 from its packaging and check that it has not been damaged in transit.

Handling and storage

To ensure the speed controller is protected before installation, handle and store the device in its packaging.

Handling on installation

A hoist must be used when handling speed controllers; for this reason they are supplied with lifting "lugs”.

The precautions described below must be respected :
