Mounting

Mounting location 

The next3 comes in IP30 with a standard coating to provide additional protection in difficult environments. We recommend installing the device in a controlled environment, limiting exposure to moisture, dust, salt, chemical, temperature changes and mechanical abrasion. The mounting location is indoors and should be protected from children and unauthorised people. 

Installation must be entrusted by qualified personnel.

The place of installation must satisfy the following criteria: 

• Protected from any unauthorised person
• Protected from water, dust and in a place with no condensation
• It must not be situated directly above vented lead acid batteries, or in a cabinet with them, due to corrosive gas
• No easily inflammable material should be placed directly underneath or close to the next3
• Ventilation holes must always remain clear and be at least 20cm from any obstacle that may affect the ventilation of the equipment (see mounting schematics)
• In mobile applications, it is important to select an installation site that ensures the lowest possible vibration level
• According to the IEC/EN 62109-1 standard, the level of pollution at the mounting place should not exceed PD2 (second-degree environment), which means that there can be pollution as long as it becomes not electrically conductive
• Protected from direct solar radiation or heat sources

As much as possible, reduce exposure to sudden temperature variations: important heat variation may create undesired and harmful condensation inside the equipment. 

Installing the next3 wall-mounted version

The next3 must be installed vertically and on a non-flammable wall or support. Distances of at least 12cm around the units and 25cm above the equipment are required to guarantee an adequate ventilation.

The next3 is a heavy equipment (~60kg) and must be mounted to a support/structure designed to bear such a load. It is imperative to ensure a complete and safe fastening of the equipment. If simply hung, it may fall down and cause severe damages. The image below show a typical mounting of the device with distances to respect for ventilation and cabling.

For the wall mounting plate, use the 5 screws and buffers capable to stand the weight of the inverter in full safety. Those are note provided in the package, make sure that you choose the right screws according to your wall type and ensuring a solid mounting. The diameter of the holes in the plate are meant for 8mm screws.

When drilling the holes, keep at least 542 mm from the top screws to the ceiling to respect the 250mm clearance above the device. Keep at least 290mm to the nearest on the left wall (150mm+454mm/2-90mm=287mm) and 350mm to the next next3 (120mm+454mm/2=347); distance from the middle of the plate.

When you fix the mounting plate on the wall, don't forget to put the fixing-belt (in yellow on the following picture) in place before screwing the mounting plate on the wall.

fix the 4 handles on the two sides of the next3 and remove the loops if you don’t need them to move the next3.

Fix the mounting plate on the wall, leaving enough space around the unit for the ventilation and cabling. Don’t forget to put the fixing-belt in place before screwing the mounting plate on the wall.

Fix the mounting plate with the fixing belt to the wall and then mount the next3 in the support with the help of the installation handles. 2 technicians are required to ensure a safe installation. Once the device is mounted in the plate, fix the belt with the device with the 2 screws provided and fix the mounting plate with the device with the screw also provided.

Those are not provided in the package, select the proper screws for your wall type and ensure a solid mounting.
The diameter of the holes in the plate are meant for 8mm screws. 

In vehicles (road or marine), or when the support undergoes significant vibrations, the next3 is to be mounted on anti-vibration elements. The fixing belt use is mandatory in those cases. Use of the wall mounting bracket delivered with the
inverter is mandatory. Warranty claims will expire if the inverter is operated without the wall mounting bracket.

For the wall mounting plate, use the 5 screws and buffers capable to stand the weight of the inverter in full safety. 

When drilling the holes, keep at least 542 mm from the top screws to the ceiling to respect the 250mm clearance above the device.
Keep at least 290mm to the nearest on the left wall (150mm+454mm/2-90mm=287mm) and 350mm to the next next3 (120mm+454mm/2=347); distance from the middle of the plate. 

Keep sufficient space below for the cabling.

The next3 is a heavy equipment (~60kg) and must be mounted to a support/structure designed to bear such a load. It is imperative to ensure a complete and safe fastening of the equipment. If simply hung, it may fall down and cause severe damages. 

For the next steps there must be 2 people at least! 

Hang the next3 on the structure.

Fix the structure at the bottom with the provided screw 

Fix the belt on the sides with the screws provided.

Fix the nx interface with 2 screws provided. Install the communication cable on the screen before mounting.

The nx-communication cable goes in the plug on the left of the nx interface and is easier to install before the mounting on the nx device. The ethernet cable (LAN) goes on the right.

See the wiring sections for details.
Special installation on the wall or in a cabinet is shown in the following chapter below.
