Eaton PowerXL DE1 series Manual - Danger!

I

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 

unintentional operation.

• Suitable safety hardware and software measures should 

be implemented for the I/O interface 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. B. BGV 4) 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 

maintenance 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's sudden stop) so as to prevent 

hazards to people and property, e.g.:

– Additional stand-alone devices for monitoring 

parameters 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.
