BASIC SAFETY INSTRUCTIONS

For a trouble-free and safe operation, please pay attention to the following instructions:

• The electrical installation shall be carried out in accordance with the relevant re-

quirements.

• Cable cross-sections and fuses must be dimensioned by the user according to the

speciedminimum/maximumvaluesfortheapplication.

• Thewiringmustbemadewithexiblecoppercableforatemperature>75°C.

• Connection of the drive converter is only permissible on symmetrical networks with

amaximumlinevoltage(L1,L2,L3)withrespecttoearth(N/PE)ofmax.300V.An

isolating transformer must be used for supply networks which exceed this value ! In

case of non-compliance the control is not longer considered to be a PELV circuit.

• With existing or newly wired circuits the person installing the units or machines must

ensure that the PELV requirements are met.

• For drive converters that are not isolated from the supply circuit (in accordance with

EN 60721-3-2) all control lines must be included in other protective measures (e.g.

double insulation or shielded, earthed and insulated).

• When using components without isolated inputs/outputs, it is necessary that equi-

potential bonding exists between the components to be connected (e.g. by the equi-

potential line). Disregard can cause destruction of the components by equalizing

currents.

1.4.1 EMC-compatible installation

Observance of the limit values required by EMC law is the responsibility of the customer.

Notes on EMC-compatible installation can be found here.

1.4.2 Voltage test

Testing with AC voltage (in accordance with EN 60204-1 chapter18.4)maynotbeexe-

cuted, since there is danger for the power semiconductors in the drive inverter.

Due to the radio interference suppression capacitors, the test generator will

switcho󰀨immediatelywithacurrentfault.

According to EN 60204-1 it is permissible to disconnect already tested com-

ponents. Drive converters of the KEB Automation KG are delivered ex works

voltagetestedto100%accordingtoproductstandard.

1.4.3 Insulation measurement

An insulation measurement (in accordance with EN 60204-1 chapter 18.3) with DC

500Vispermissible,ifallpowerunitconnections(grid-connectedpotential)andallcon-

trol connections are bridged with PE. The insulation resistance of the respective device

can be found in the technical data.
