Schakelkasten installeren: netjes, veilig en goed geventileerd – ook buiten

Whether you're setting up a camera installation, a solar power system or network infrastructure, an enclosure is essential for a neat, safe and durable finish. Enclosures protect your equipment against dust, moisture, vandalism and heat. In this article you'll learn everything about choosing, installing and ventilating enclosures – both indoors and outdoors.

1. What is an enclosure and what is it used for?

An enclosure (also called a control cabinet or electrical housing) is a closed cabinet that safely houses electrical and electronic components. Think of power supplies, fuses, relays, network equipment, charge controllers or inverters.

Applications:

  • Video surveillance (NVR, switch, power supply)
  • Off-grid power (charge controller, inverter, fuses)
  • Networking (patch panels, routers, PoE injectors)
  • Access control (relays, power supplies, controllers)

A good enclosure gives you a well-organised, safe installation that lasts.

2. Indoors or outdoors? Choosing the right enclosure

Indoor use:

  • IP20 or IP30 is usually sufficient (dust protection)
  • Metal or plastic
  • Secured with a lock or screws

Outdoor use or damp locations:

  • At least IP65 (dust-tight and waterproof)
  • UV-resistant plastic or stainless steel
  • A good seal with a rubber gasket
  • Optional rain hood or wall bracket

Tip from UMATECH: our waterproof outdoor enclosures with mounting plate and cable glands are ideal for camera poles or access control systems.

3. Size and layout

The dimensions of the enclosure depend on:

  • The number of components
  • Space for cable management
  • Any cooling or ventilation

Keep in mind:

  • Enough space between components (heat!)
  • Room for future expansion
  • Clear separation between 230 V and low-voltage wiring

Use DIN rails, mounting plates or blanking plates to mount components neatly and securely.

4. Ventilation and cooling: don't underestimate it

Electronics generate heat, especially in closed enclosures. Overheating leads to faults or failures.

Cooling solutions:

  • Ventilation grilles with filters (to keep dust out)
  • Miniature fans (12 V/24 V)
  • Active cooling units for heavy use or outdoor enclosures in direct sun

For outdoor enclosures:

  • Mount them in the shade or use a sun shield
  • Choose a white or reflective housing
  • Leave enough space around sensitive equipment

UMATECH supplies ready-to-install ventilation kits for enclosures.

5. Connections and cabling: neat and safe

A messy enclosure isn't just unprofessional, it's also unsafe. So always work neatly and with the right tools.

Practical tips:

  • Use cable glands (PG/M20) for watertight cable entry
  • Label all cables and connections
  • Use cable trunking or spiral wrap to bundle cables
  • Terminate power lines with terminal blocks or splice connectors
  • Install fuses or circuit breakers for each circuit

Earthing:

  • Always earth metal enclosures
  • Use a separate earth bar when working with 230 V

6. Enclosures on camera poles and exterior walls

For video surveillance or intercom systems mounted on a pole or exterior wall, a robust enclosure is essential. Consider:

  • An enclosure with IP65 protection
  • Mounting with stainless steel brackets or an internal bracket
  • Space for a power supply, switch and optionally a 4G router

WL4 poles from UMATECH are compatible with universal outdoor enclosures and come with gland holes for cabling.

7. Accessories and extra options

Consider the following accessories for your installation:

  • DIN rail power supplies
  • Time relays or timer switches
  • RJ45 couplers or network cable feed-throughs
  • Temperature sensors with fan trigger

At UMATECH you can order enclosures ready-made, pre-fitted with cable glands, DIN rail and cable entries. Feel free to ask about the options.

8. Maintenance and inspection

Even a good installation needs maintenance:

  • Check annually for moisture, dust and insects
  • Test fans and filters
  • Check that the cabling is still securely fastened
  • Replace damaged cable glands or seals

An annual check is especially recommended for outdoor installations.

9. Summary

A well-chosen and correctly installed enclosure:

  • Protects your installation against weather, dust and overheating
  • Keeps things organised and safe
  • Increases the reliability of your system

For outdoor use, think about waterproofing, ventilation and sun exposure. Work neatly, use the right accessories and inspect regularly.
