Safety Precautions
SHOCK HAZARD
Disconnect and lock out power before servicing.
Discharge all capacitors before servicing.
Use compressor with grounded system only.
Molded electrical plug must be used when
required.
Refer to original equipment wiring
diagrams.
connections must be made by qualified electrical personnel.
Failure to follow these warnings could result in serious personal injury.
WARNING
Before Performing the Installation
•
It is strongly recommended to read through
this entire manual for safe and correct
installation.
•
Disconnect the power supply of the device.
•
Ensure that the devices cannot be accidentally
restarted.
•
Verify isolation from the supply.
•
Earth and short circuit the device.
•
Cover or enclose any adjacent live components.
•
Only suitably qualified personnel in accordance
w
ith EN 50110-1/-2 (VDE 0105 Part 100) may
work on this device/system.
•
Before installation and before touching the device
ens
ure that you are free of electrostatic charge.
•
The functional earth (FE, PES) must be
connected to the protective earth (PE) or t
he
pot
ential equalization.
•
The system installer is responsible for
implementing this connection.
•
Connecting cables and signal lines should be
i
nstalled so that inductive or capacitiv
e
i
nterference does not impair the automation
functions.
•
Install automation devices and related operating
el
ements in such a way that they are well protect
ed
agai
nst unintentional operation.
•
Suitable safety hardware and software measures
should be implemented for the I/O interface so
that an open circuit on the signal side does not
result in undefined states in the automation
devices.
•
Ensure a reliable electrical isolation of the extra- low
voltage of the 24 V supply. Only use power supply
units complying with IEC 60364-4-41 (VDE
0100
P
art 410) or HD384.4.41 S2.
•
Deviations of the input voltage from the rated value
m
ust not exceed the tolerance limits given in t
he
s
pecifications, otherwise this may cause malfuncti
on
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-stop devices must not cause a restart.
• Measures should be taken to ensure the proper restart of
pr
ograms interrupted after a voltage dip or failure.
•
This should not cause dangerous operating
s
tates even for a short time. If necessary,
emergency-stop devices should b
e
i
mplemented.
•
Wherever faults in the automation system may
cause injury or material damage, external measures
must be implemented to ensure a safe operati
ng
s
tate in the event of a fault or malfunction (for
example, by means of separate limit switches,
mechanical interlocks, and so on).
•
Depending on their degree of protection,
adjustable frequency drives may contain liv
e
br
ight metal parts, moving or rotati
ng
c
omponents, or hot surfaces during
and
i
mmediately after operation.
•
Removal of the required covers, improper
installation, or incorrect operation of motor or
adjustable frequency drive may cause the failur
e
of
the device and may lead to serious injury or
damage.
•
The electrical installation must be carried out in
ac
cordance with the relevant regulations (for
example, with regard to cable cross sections,
fuses, PE).
•
Installations containing adjustable frequency
drives must be provided with additional monitoring
and protective devices in accordance with the
applicable safety regulations. Modifications to the
adjustable frequency drives using the operati
ng
software are permitted.
•
All covers and doors must be kept closed during
oper
ation.
•
Never touch live parts or cable connections of the
adjustable frequency drive after it has
been
di
sconnected from the power supply. Due to the
charge in the capacitors, these parts may still be liv
e
af
ter disconnection. Fit appropriate warning signs.
