Before Starting With The Installation - Eaton easyE4 Manual

DANGER!
Hazardous electrical voltage!

Before starting with the installation

Installation requires qualified electrician
l
Disconnect the power supply of the device.
l
Secure against retriggering
l
Verify isolation from the supply
l
Ground and short-circuit
l
Cover or enclose any
l
neighboring live parts.
Follow the engineering instructions (IL) of the
l
device concerned.
Only suitably qualified personnel in accordance
l
with EN 50110-1/-2 (VDE 0105 part 100) may work on
this device/system.
Before installation and before touching the device
l
ensure that you are free of electrostatic charge.
The functional earth (FE) must be connected to the
l
protective earth (PE) or to the equipotential bond-
ing. The system installer is responsible for imple-
menting this connection.
Connecting cables and signal lines should be
l
installed so that inductive or capacitive inter-
ference does not impair the automation functions.
Install automation devices and related operating
l
elements in such a way that they are well protected
against unintentional operation.
Suitable safety hardware and software measures
l
should be implemented for the I/O interface so that
a line or wire breakage on the signal side does not
result in undefined states in the automation
devices.
Deviations of the mains voltage from the nominal
l
value must not exceed the tolerance limits given in
the specifications, otherwise this may result in mal-
function and hazardous states.
Emergency-Stop devices complying with IEC/EN
l
60204-1 must be effective in all operating modes of
the automation devices. Unlatching the emergency
switching off devices must not result in an auto-
matic restart.
Built-in devices for enclosures or cabinets must
l
only be run and operated in an installed state;
desktop devices and portable devices only when
the housing is closed.
Measures should be taken to ensure the proper
l
restarting of programs interrupted after a voltage
dip or outage. This should not result in dangerous
operating states even for a short time. If necessary,
emergency switching off devices should be imple-
mented.
Wherever faults in the automation system may
l
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.).
