Connectors Series M – Installation and Maintenance Instructions
General and Security Information
X
Work on electric equipment may only be performed
by an expert or trained personnel working under
the direction and supervision of an expert accord-
ing to the applicable rules of electrical engineering.
X
An expert is a person who can judge and recognise
the possible dangers of the jobs commended to
him based on his training, knowledge and experi-
ence and by knowledge of the appropriate regula-
tions.
X
Sta must be informed clearly about who is re-
sponsible for the maintenance of the connectors.
2.3 Intended Use
X
The connectors supply power and signals. They
are intended for plugin and detachable connec-
tions of components, devices and systems only.
X
In order to comply with DIN EN IEC 61984 make
sure that always the live side of the connector – no
matter whether plug or receptacle – is tted with
socket contacts.
X
A symmetrical assembly of the contact insert is
not permitted. Please refer to the chapter „6. Cable
Assembly and Processing“.
X
None of the operating conditions dened in our
catalogue “A10.en” in section “Specications”,
such as voltages, currents, ambient conditions,
etc. may be changed.
X
Work on the connectors must only be carried out
by sta who meets the requirements set out in
these installation and maintenance instructions.
X
According to DIN EN IEC 61984 connectors used
as intended must not be engaged or disengaged
when live or under load.
X
A connector that does not engage easily requires
special attention:
Check for the correct orientation, pollution or if
contacts got bent. Remedy the cause without de-
lay. Never use force! The connector should always
engage easily.
X
In order to meet the requirements of the protec-
tion class and to prevent the connectors against
the entry of dirt or moisture, make sure that plugs
and receptacles, when not mated, are always
closed with protection caps.
X
When disengaging a connector, pull the plug and
never the cable.
X
Use the connector only according to its intended
use. Replace or repair damaged parts exclusively
with original parts. Any other usage of or tamper-
ing with the connector is considered contrary to its
intended use. No liability is assumed for damages
and accidents caused due to non-compliance with
the instructions or improper use of the connector.
2.4 Ambient Conditions
NOTICE
The connectors are constructed for specic ambient
conditions.
X
Operate the connectors only under the ambi-
ent conditions, like temperature ranges and IP
protection classes as dened in our catalogue
A10.en in section “Specications“ (schaltbau.
info/download1en).
Note:
In case of a very low or very high ambient temperature
which approximates the limits of the allowable oper-
ating temperature range specied in our catalogue
A10.en in section “Specications”,
- a higher eort may be needed for the plugging and
unplugging and
- the operational life span of plug and coupling recep-
tacle may thus be reduced due to increased wear and
tear.
