Product Description

These compact and easy-to-mount sockets by MRS Electronic are perfect to use with our modules. They also allow you to integrate flat receptacles and then fix them with cables very easily.

Transport and Storage

Transport
The product must be packed in suitable transport packaging and secured against sliding around. During transport, the statutory provisions regarding securing loads must be observed. If the watertight socket falls down and exhibits any damage, it may no longer be used.

Storage
Store the product in a dry place (no dew), dark (no direct sunlight) in a clean room which can be locked. Please observe the permissible environmental conditions in the data sheet.

Use

Socket package watertight (modules 1.017.010.24, 1.017.010.25, 1.017.010.30, 1.017.010.40, and 1.017.010.50) can be used with MRS relays. The clamping bracket, sealing pad and individual wire seals ensure impermeability to water. The Socket 12-pin MicroPlex® / ISO 280 is perfect for your application in use with our patented MicroPlex® or two ISO 280 relays. Thanks to the practical snap-in principle, the socket can be assembled without tools. Due to the lateral guides, several sockets can be plugged together and thus also easily combined with other MRS sockets.

You are within regulations:

If the watertight socket is used within the operating ranges specified and approved in the corresponding data sheet.
If you strictly adhere to the information and sequence of tasks described in these operating instructions and do not engage in unauthorized actions which may risk your safety and the functionality of the watertight socket.

If you comply with all specified safety instructions.

WARNING!
DANGER DUE TO UNINTENDED USE!
The watertight socket is only intended to be used in vehicles and self-propelled work machines.

An application in safety-relevant system parts for functional safety is not permitted.

Please do not use the watertight socket in explosive areas.

Misuse

Use of the product in conditions and requirements differing from those specified by the manufacturer in technical documentation, data sheets and operating instructions.

Operation without the safety measures intended and provided by the manufacturer. MRS only guarantees/is liable for the watertight socket corresponding to the published specifications. If the product is used in a way not described in these operation instructions or in the data sheet of the watertight socket in question, the protection of the watertight socket will be impaired, and the warranty claim is void.

Assembly

Assembly work may only be performed by qualified staff (see Chapter 2.2 Staff Qualifications). The watertight socket may only be used after having installed in a fixed location.

INFORMATION
If the watertight socket falls down and exhibits any damage, it may no longer be used.

Mounting Location
The mounting location must be selected as such that the watertight socket is subjected to as low a mechanical and thermal load as possible. The watertight socket may not be exposed to chemicals (except the chemicals mentioned in the corresponding data sheet).

INFORMATION
Please observe the permissible environmental conditions in the data sheet.

Mounting of the Watertight Socket

Mount the watertight socket in such a way that the cable harness points vertically downwards. Individual seals of the cables/wires ensure that no water can enter the watertight socket. Compliance with the IP protection class and protection against touching must be ensured by using the appropriate accessories in accordance with the accessories list in the data sheet.
Select the appropriate crimps (according to the accessories list in the data sheet) and the appropriate wire cross-sections for mounting the watertight socket.

Select the appropriate single wire seals for the wire cross-sections.
The crimps with cable must be inserted into the socket from below until they click into place.
The single wire seals must be inserted into the socket from below so that they are flush with the edge of the socket.

The lower fixing screw (cylinder head screw or pan head screw with minimum strength class 4.6 in size M5) must be screwed into the fixing plate/baseplate at a distance of 2 mm between the screw head and the fixing plate/baseplate.
The watertight socket is pushed onto the lower fixing screw from above.
The upper fastening screw (cylinder head screw or pan head screw with minimum strength class 4.6 in size M5) must be screwed in through the upper fastening hole (tightening torque: 1.6 Nm to 2 Nm).

The sealing pad must be inserted into the watertight socket from above so that the position of the slots in the sealing pad matches the position of the slots in the socket.
A module matching the watertight socket is then inserted into the socket until flush with the sealing pad.
See also Figure 1 and Figure 2.

If you want to use the cables again after removing the watertight socket (see chapter 11.1 Disassembly), check the crimps and the individual wire seals/blind plugs for cleanliness and proper function.
