A manufacturer of products using the
technology.
GENERAL
The DB MOTOR DECONTACTOR™ combines in a
single unit, the performances of a plug and socketoutlet for industrial purposes with that of a air-break
motor switch.
It is designed to make and break highly inductive
loads and harsh overloads in complete safety. It is a
switch with utilisation categories of AC22, AC23 and
AC3 according to IEC/EN 60947-3 standard.
Socket-outlet contacts are protected against small
tools and wires (IP4X) according to IEC/EN 60529
standard.
INSTALLATION
The DB MOTOR DECONTACTOR™ must be
installed by qualified electricians.
Assembly
Optimum operating conditions are achieved by
installing the MOTOR DECONTACTOR™, with the IP67
indication at the top.
Note : Do not forget the gasket between the inlet or
socket-outlet and its back accessory. Make sure the
blanking cap supplied with surface boxes for the unused entry, if any, is properly tightened.
Fixing screws
Care must be taken to use the appropriate tool for
each type of screw. Apply the required torque to the
self-tapping screws. Do not overtighten the screws
supplied with polymeric accessories.
• Back out terminal screws far enough (but not
completely) to allow a complete insertion of
conductors.
Wiring terminals of the MOTOR DECONTACTOR™
are spring-assisted to prevent loosening due to
strand settlement, vibration or thermal cycling.
Respect the recommended torque.

OPERATION
To ensure a safe and reliable operation, the MOTOR
DECONTACTOR™ has to be used according to its
designed destination, and in particular its assigned
ratings, in terms of current, voltage, IP and endurance
(according to IEC/EN 60309-1).
To be connected together, the plug and the socketoutlet of the MOTOR DECONTACTOR™ must have
identical rated voltage and current and compatible pin
configurations.
When not in use the socket-outlet is shielded by a
protective lid. This is held in the closed position by a
locking ring, thereby preventing the entry of dust and
moisture. To release the lid, turn the ring fully
anticlockwise. The lid is then retained by a strong
nylon wire.
• Plug and connector:
Insert cable through handle, strip conductors to
adequate length (see table) and twist strands of
each conductor together. Alternatively, place a
wiring ferrule onto the conductor. Insert conductors fully into their respective terminals and
tighten the wiring screws manually with an appropriate tool (see recommended torques and tools).
After assembly, the cable sheath must extend into
the handle. Assemble handle with screws and
gasket, and tighten cable gland. Whilst clamping
or anchoring, the portion of cable inside the
handle must not be tight.
For a proper clamping the use of PVC cables is not
recommended.
• Socket-outlet and appliance inlet on box:
Insert cable through surface box glanding arrangement and strip conductors to adequate length
(see table). Insert conductors fully into their
respective terminals and tighten the wiring screws
manually with an appropriate tool (see recommended torques and tools). Assemble socketoutlet or inlet on adapter or box, using gaskets and
screws supplied, and tighten cable gland. Ensure
that the blanking cap supplied with the surface
box for unused entry, if any, is properly tightened.
To connect the plug, align its bayonets and the hollow
parts of the socket-outlet, push the plug partially,
locking finger facing upward, and turn it clockwise as
an electric light bulb.
The plug is then in the rest position, circuit open. This
is indicated by a «green» window located on the front
of the socket-outlet. At this stage, the plug can be
consignated into the socket-outlet by means of a
conventional lock-out.

Socket-outlet multiple padlocking and lock-out
A standard lock-out can be used:
• to lock the cover and deny access to the socketoutlet,
• to lock the plug into the socket-outlet with the
switch in the «off» position (green indicator),
• and if this corresponds to a safety position, to lock
the plug into the socket-outlet with the switch
«on» (red indicator).
For this last possibility (which may be unwanted on
some pieces of equipment), a knock-out hole, located
on the locking ring of the socket-outlet, has to be
opened with the help of a 6-mm pin drift.
In absence of a lock-out, the circuit is finally closed by
pushing the plug fully home until it is held by the
locking ring. The window located on the front of the
socket-outlet becomes «red». IP67 is achieved by
turning the ring clockwise. If the knock-out hole has
been opened, the plug can be padlocked into the
socket-outlet.
Note: Locking off the socket-outlet does not guarantee a lock-out of the energised equipment.
Plug lock-out
Place a padlock or a safety lock-out through the hole
provided in the plug locking finger, to deny its access
to any socket-outlet.
Contact surfaces may be checked for cleanliness. Any
deposit of dust can be rubbed off with a clean cloth.
Under no circumstances should the contact surfaces
be filed as this will remove the silver-nickel tip and
reduce the effectiveness of the contact. Sprays should
not be used as they tend to collect dirt.
IP gaskets between the plug and socket-outlet bodies
should be inspected periodically. Replace gaskets as
needed.
Any repair or service must be achieved with
genuine
parts only.
Plug has to be brought back to its rest position
before another engagement is possible.
A
product must be used with a
complementary accessory only.
MARECHAL ELECTRIC S.A.’s responsibility cannot be
engaged in case
products would be associated with socket-outlets, inlets or spare parts other
than from
.
MARECHAL ELECTRIC S.A.’s responsibility is strictly
limited to the obligations expressly agreed in its
general sales conditions. Any penalty or indemnity
provided herein will be considered as lump damages,
redeeming from any other sanctions.
DECLARATION OF CONFORMITY
The DB MOTOR DECONTACTOR™ uses the
technology.
It has been designed, manufactured and controlled in
a strict respect of the relevant international and
European standards, laws and directives, and particularly of the European Low Voltage Directive
2006/95/CE. It bears the CE marking whenever
applicable.
MAINTENANCE
From time to time, the fastening screws should be
checked for tightness. Care should be taken that the
weight of the cable is taken by the glanding
arrangement and not by the terminals themselves.
To release the plug, simply turn the ring fully anticlockwise. The circuit is open (green indicator) and the
plug is in its parked position.
RESPONSIBILITY
The CE marking does not apply to spare parts and
components supplied separately.
For the MOTOR DECONTACTOR™
DB3, DB6, DB9,
and whenever it is in the scope of the 2006/95/CE
Directive:
We,
MARECHAL ELECTRIC S.A.,
5 avenue de Presles - F-94417 Saint-Maurice Cedex - France
Declare that the DB MOTOR DECONTACTOR™
satisfies the measures set in the Low Voltage Directive
2006/95/CE and in the application decrees of
member states.
