1. Important basic information
1.1 Legal notes
Without prior written consent of Schaltbau GmbH, this
manual is not allowed to be electronically or mechani-
cally reproduced – as a whole or in parts – be distrib-
uted, changed, transmitted, translated into another
language or used in any other way.
Schaltbau GmbH cannot be held liable for damage
caused by not observing (or only partly observing) the
manual.
1.2 Conventions for this manual
This manual describes the installation, commisioning
and maintenance of the contactors.
Cross references are presented in bold italics.
To highlight particularly important safety instructions
and other information, the following symbols are used
in this instructions:
DANGER
Indicates a hazardous situation with a high level
of risk which, if not avoided, will result in death or
serious injury.
WARNING
Indicates a hazardous situation with a medium level
of risk which, if not avoided, could result in death or
serious injury.
CAUTION
Indicates a hazardous situation with a low level of
risk which, if not avoided, may result in minor or
moderate injury.
NOTICE
Indicates a hazardous situation which, if not avoided,
may result in property damage, such as service inter-
ruption or damage to equipment or other materials.
Refers to technical features and methods
aimed at facilitating work or to particu-
larly important information.

The CP series devices can be congured as normally
open/normally closed contactors, disconnectors or
change-over switches. Depending on the congura-
tion, the following abbreviations are used in this man-
ual:
- NO = Normally Opened
- NC = Normally Closed
- CO = Change Over
Since the CP series devices oer a wide range of con-
guration options, not all possible congurations can
be presented in this manual.
Even if the congurations shown do not correspond ex-
actly to the present device, the installation and mainte-
nance steps can be carried out identically as described
in this manual.
2. General and security information
The contactors dealt with in this document are intend-
ed for use with high-voltage systems for special instal-
lations. They are designed and tested in compliance
with the generally recognised state of the art. However,
improper use, operation, handling, maintenance of or
tampering with electric equipment can cause serious
or fatal injury to the user or others, and the appliance or
other property can be damaged.
The operation, maintenance and installation instruc-
tions for the contactors must therefore be strictly fol-
lowed.
Any uncertainties must be claried and all queries must
include details of the type of device and the serial num-
ber.
Only authorized and trained personnel are allowed to
plan and carry out all mechanical and electrical installa-
