Marechal DN9C Plugs – 9 Contacts 30A 415V IP54/55 Multi-Contact Connectors

Product Overview

Marechal DN9C plugs and sockets are metal multi-contact connectors and have a rated current of 30A, a maximum voltage of 415V and up to 9 contacts.

DN9C connectors form part of the Marechal range of signal and control plugs – multicontact connectors (5 to 37) with waterproof electrical sockets to IP66/IP67 and IK08 IK09 protection for electrical equipment against external mechanical impacts.

The DN9C is available with a wide range of voltages and polarity options for both female socket outlets and male inlet plugs:

• 50V, 6P
• 50V, 7P
• 50V, 8P
• 50V, 9P
• 415V, 5P+E
• 415V, 6P+E
• 415V, 7P+E
• 415V, 8P+E

Marechal DN9C Plugs & Power Distribution Systems

Marechal DN9C decontactors (plug and socket outlets with integral power switch) are supported by an ancillary range of wall mounting sockets, wall boxes, socket outlets, sleeves, inlets and handles.

Installation & Operation Guidelines

• To ease their operation, the devices must be installed as follows :
• Install socket-outlets with the latch at the top (Figure C1), or on the side in case of risk of accumulation of foreign material inside the cover.
• Install appliance inlets with the catch at the top. The use of connectors with cover opening at 180° may be necessary. See figure C2.
• When this is not possible, install appliance inlets with the catch at the bottom. See figure C3.
• When facing downwards, IP54 appliance inlets do not protect the mating connectors against streaming water. Use IP66 devices. See figures C2/C3.

Wiring

• Remove an adequate length of cable outer sheath according to the accessory used. Ensure that the cable sheathing extends through the cord grip into the handle or box as required to achieve the intended sealing and cord gripping performance.
• Strip conductor insulation to the length indicated. See table T1
• Do not back terminal screws completely out ;
• Fully insert the conductor and tighten the terminal screws to the torque indicated. See table T1.

Mouldings display a double marking according to their use, emitting side or receiving side :

• socket-outlet/connector terminal numbers are preceded by an “S”;
• plug/inlet terminal numbers are preceded by an “F”.

E.g. F4/S2 : This terminal receives conductor n° 4, plug side and conductor n° 2, socket-outlet side.

• DN9C socket-outlet/connector : see figure F2,
• DN9C plug/inlet : see figure F3,

Tension Cord

The release of the latch is performed by a tension cord. One end of this cord must be attached either to the flexible cable or to a suitable fixed point of the installation. The other end is attached to the latch release mechanism.

Latch Release Mechanism

This mechanism comes in two different types :

• Ejecting connector : The retaining latch is directly activated by the tension cord in case of traction. See figure E1.
• Ejecting plug : A mechanism is assembled on the plug. It releases the retaining latch of the socket-outlet in case of traction on the tension cord. See figure E2.

For the larger plugs, a cam mechanism inserted between the plug top and the handle. See figure E3.

Eyelet

Some handles are equipped with an eyelet. This eyelet allows an optimal pulling angle of the tension cord on the latch release mechanism. See figures E1/E2.

Assembly

The end of the tension cord that must be attached either to the flexible cable or to a suitable fixed point of the installation is equipped with a loop. A crimping ferrule is supplied to loop the other end of the cord, once it has been passed through the handle eyelet, the latch release mechanism, and cut to the adequate length.

Cable Tie

A cable tie is supplied, to attach the loop of the tension cord onto the flexible cable.

Sealing Rings

Insert a sealing ring between the device and its rear accessory (handle, angle, etc.). The two protrusions of the rings must be positioned on the latch side for the socket-outlet/ connector and on the catch side for the plug/appliance inlet.

Operation

• The socket-outlet is shielded by a protective lid held in the closed position by a latch.
• Depress the latch to release the lid. See figure F5.
• To connect, align the bayonets of the device with the hollow parts of the complementary device. Insert the device and turn until the stop. The device is in the rest position, circuit open.
• Push the device fully home until latched.
• To disconnect, depress the latch. The device returns to its rest position.
• Turn the device clockwise to remove it. Shut the lid.

Self-Ejecting Devices (Marechal DN Only)

1. Lift the latch to release and open the lid.
2. Align the plug/inlet catch with the socket-outlet retaining latch and push the mobile part fully home until it is held in place by the latch.
3. To release the mobile part, pull on the tension cord. Check that the cover is properly closed.
