Eaton 118701, Manual

Before commencing the installation

• Disconnect the power supply of the device. 

• Ensure that devices cannot be accidentally retriggered.

• Verify isolation from the supply.

• Ground and short-circuit.

• Cover or enclose neighbouring units that are live. 

• Follow the engineering instructions (IL) of the device 

concerned.

• Only suitably qualified personnel in accordance with 

EN 50110-1/-2 (VDE 0105 Part 100) may work on this device/
system.

• Before installation and before touching the device ensure 

that you are free of electrostatic charge. 

• The functional earth (FE) must be connected to the 

protective earth (PE) or to the potential equalizing.
The system installer is responsible for implementing this 
connection.

• Connecting cables and signal lines should be installed so 

that inductive or capacitive interference do not impair the 
automation functions.

• Install automation devices and related operating elements 

in such a way that they are well protected against uninten-
tional operation.

• Suitable safety hardware and software measures should 

be implemented for the I/O connection so that a cable or 
wire breakage on the signal side does not result in 
undefined states in the automation device.

• Ensure a reliable electrical isolation of the low voltage for 

the 24 V supply. Only use power supply units complying 
with IEC 60364-4-41 or HD 384.4.41 S2 (VDE 0100 part 410).

• Deviations of the mains voltage from the nominal value 

must not exceed the tolerance limits given in the technical 
data, otherwise this may cause malfunction and 
dangerous operation.

• Emergency-Stop devices complying with IEC/EN 60204-1 

must be effective in all operating modes of the automation 
devices. Unlatching the emergency switching off devices 
must not cause restart.

• Built-in devices for enclosures or cabinets must only be 

run and operated in an installed state, desk-top devices or 
portable devices only when the housing is closed.

• Measures should be taken to ensure the proper restart of 

programs interrupted after a voltage dip or failure. This 
should not cause dangerous operating states even for a 
short time. If necessary, emergency switching off devices 
should be implemented.

• Wherever faults in the automation system may cause 

damage to persons or property, external measures must 
be implemented to ensure a safe operating state in the 
event of a fault or malfunction (for example, by means of 
separate limit switches, mechanical interlocks, etc.).

• During operation, and depending on their degree of 

protection, variable frequency drives may have live, 
uninsulated, moving, and/or rotating parts, as well as hot 
surfaces.

• The impermissible removal of the required cover, 

improper installation or incorrect operation of the motor or 
variable frequency drive can cause the failure of the 
device and serious injury and/or material damage.

• Comply with all applicable national accident prevention 

regulations (e.g. BGV A3) when working with energized 
variable frequency drives.

• The electrical installation must be carried out in 

accordance with the relevant regulations (e.g. with regard 
to cable cross sections, fuses, PE).

• All transport, installation, commissioning and mainte-

nance work must only be carried out by trained personnel 
(observe IEC 60364, HD 384 or DIN VDE 0100 and national 
accident prevention regulations).

• If applicable, systems in which variable frequency drives 

are installed must be equipped with additional monitoring 
and protective devices in accordance with the applicable 
safety regulations, e.g., the German Equipment and 
Product Safety Act, accident prevention regulations, etc. 
Making changes to the variable frequency drives by using 
the operating software is allowed.

• Keep all covers and doors closed during operation.

• When designing the machine, the user must incorporate 

mechanisms and measures that limit the consequences of 
a drive controller malfunction or failure (an increase in 
motor speed or the motor?9s sudden stop) so as to prevent 
hazards to people and property, e.g.:

– Additional stand-alone devices for monitoring parame-

ters that are relevant to safety (speed, travel, end 
positions, etc.)

– Electrical and non-electrical safety devices (interlocks 

or mechanical locks) for mechanisms that protect the 
entire system

– Due to the possibility of there being capacitors that are 

still holding a charge, do not touch live device parts or 
terminals immediately after disconnecting the variable 
frequency drives from the supply voltage. Heed the 
corresponding labels on the variable frequency drives
