Contactors CP Series – Installation and Maintenance Instructions
General and security information
tions, transport, commissioning, as well as maintenance
and repair work. This applies to the observation of the
general installation and safety regulations for high-volt-
age systems as well as the proper use of tools approved
for this purpose. Electric equipment requires protection
from moisture and dust during installation and storage.
2.1 Observing the instructions
X
All sta must read and understand the instructions
in this manual and adhere to them when working
with the device.
X
Always carefully observe all safety warnings!
2.2 User obligations
X
Observe all applicable national provisions, all safe-
ty, accident prevention and environmental regula-
tions as well as the recognized technical rules for
safe and proper working.
X
Carry out regular inspections of all protection and
safety devices to see if they work properly.
X
Work on electric equipment may only be per-
formed by an expert or trained personnel working
under the direction and supervision of an expert
according to the applicable rules of electrical en-
gineering.
X
An expert is a person who can judge and recog-
nise the possible dangers of the jobs commended
to him based on his training, knowledge and ex-
perience and by knowledge of the appropriate
regulations.
X
Work on the contactors must only be carried out
by sta who meets the requirements set out in this
manual.
X
Sta must be informed clearly about who is re-
sponsible for the maintenance of the contactors.
X
After each installation work and after replacement
of main contacts, contact bridge or after any other
modications, alterations or maintenance works,
always perform complete checks according to
these standards:
- IEC 60077-2
- IEC 60947-4-1
2.3 Intended use
X
The contactors have been designed and tested ac-
cording to national and international standards.
Due to their unique features they can also be used
in a variety of applications.
X
The contactors must only be used under operating
conditions according to the technical specication
and the instructions in this manual.
X
None of the operating conditions dened in our
catalogues C40 in section “Specication“, such as
voltages, currents, ambient conditions, etc. may
be changed.
X
The contactors must only be used when all protec-
tive devices are present, have been installed prop-
erly and are fully operational.
X
The contactors must not be contaminated with
aggressive media.
X
Contactors may not be used without further pro-
tective measures in potentially explosive atmos-
pheres.
X
The switching device meets the requirements
of basic insulation. Make sure the frame or plate
onto which the drive of the contactor is mounted
is earthed in a shock and vibration resistant way.
X
Do not use the contactor without properly mount-
ed arc chute (if applicable).
X
The contactor has unprotected live parts and car-
ries labels that warn of the hazard. This caution
must be observed and the labels must not be re-
moved in any way.
X
The required clearance of live parts to earth and
other parts of the contactor is to be observed as
well as the safety regulations of the applicable
standards.
X
Switching at maximum breaking capacity might
require larger clearance! Do not hesitate to ask our
advice for dimensioning.
X
Coil suppression for reducing surges when the coil
is switched o is optimally attuned to the contac-
tor‘s switching behaviour. The existing opening
characteristic must not be negatively inuenced
by parallel connection with an external diode.
X
Improper handling of the contactors, e.g. when
hitting the oor with some impact, can result in
breakage, cracks and deformation. Always handle
the contactors with care.
X
Use the contactor only according to its intended
use. Replace or repair damaged parts exclusively
with original parts. Any other usage of or tamper-
ing with the contactors is considered contrary to
its intended use. No liability is assumed for damag-
es and accidents caused due to non-compliance
with the instructions in this manual or improper
use of the contactors.
