Service temperature
Permitted service temperature -50°C to +180°C. The permitted operational temperature range must be considered for internal components.

Attention:
Empty enclosures with component certificates require an examination certificate of a notified body for overall approval.

Installation

For the installation and operation of explosion-protected enclosure variants, the recognized rules of technology in accordance with EN 60079-14 “Configuring and selection”, and EN 60079-17 “Test and maintenance”, and the accompanying installation and operating instructions must be observed.

Installation location
The installation location for explosion-protected enclosure variants must be chosen to prevent any damage caused by industrial trucks or forklift trucks.
Explosion-protected enclosure variants installed on support frameworks must be protected from falling over.

Service temperature
To maintain the determined surface temperature, the environment temperature limit values may not be undershot or overshot (-50°C to +180°C) .
Any present external heat sources or solar radiation may cause additional heating of the enclosure. Appropriate measures should be considered during the installation

Cable and wire entries

• Cable and wire entries as well as sealing plugs made of metal can be used. All cable and wire entries must have a separate EU prototype test certificate.
• The maximum number of entries listed in the table for each side of the enclosure has been defined to avoid weakening of the side panels or degrading the stability of the enclosure.
• All cable and wire entries must be installed using a metal counter nut.
• The number of possible standard cable glands decreases if strain relief or cable guards are used.
• Unused openings for cable and wire entries must be closed with metal plugs that have a separate EU prototype test certificate,
• The cable and wire entries must be installed so that a self-loose ending is prevented, and the permanent sealing of the cable and wire entry locations can be guaranteed.
• The distances between the cable entries should be chosen so that a torque wrench can be used to tighten the cable and wire entries and the box nuts.
• The tightening torques must be observed for the installation of the cable and wire entries.

Maximum number of cable and wire entries

The maximum number of cable/wires entries on the Ex-enclosures isss as follows
THE INFORMATION CONTAINED IN THE OPERATING INSTRUCTIONS PROVIDED BY THE MANUFACTURERS OF CABLE AND WIRE ENTRIES MUST BE OBSERVED.

Enclosure attachment

Ex large Enclosure: Instruction Manual – Ex Large Enclosure

PE conductor / equipotential bonding conductor (PA) connection.

• As a general rule, the outer protective conductor or an equipotential bonding conductor must be connected.
• An internal and external connection point located at the empty enclosure is provided for this purpose. The connection must be performed in agreement with EN 60079-0, Section 15.
• Connect the PE / equipotential bonding conductor as described on drawing NO. N131348 00 EX A3 sheet 3/5, using the stainless-steel screws, nuts, plain washers, and split washers that accompany the empty enclosure. Attach a standard cable lug with the appropriate cross-section and ring diameter to the PE / equipotential bonding conductor which is fed in from the outside. The cable lug you select should fulfill the requirements for ring cable lugs defined in the DIN 46234 standard or for spade-type cable lugs defined in the DIN 46235 standard.
• The terminals for the protective earth and equipotential bonding conductor are designed to accept at least one conductor. The cross-sections must be selected as follows:
  Cross-sectional area of phase conductors, S mm2| Minimum cross-sectional area of the corresponding PE protective conductor Sp mm2
  ---|---
  S≤ 16 16 <S≤35

s >35 mm2

| S 16

0.5 S

The PE / equipotential bonding conductor terminal fittings are designed for a minimum cross-section of 4 mm².
When you are installing the outer conductor / equipotential bonding conductor, be sure that you route the conductor properly in a fixed position near the enclosure main body to ensure that the conductor will not rotate or become loose. Torque the screwed connection to 10 Nm to provide sufficient contact pressure using the split washer provided.
The SL / PA connection between the enclosure’s main body and the door must be achieved with a flexible connector marked in green/yellow. Select the cross- section to match the heaviest installed gauge outer conductor but not less than 4 mm² if the cross-section table above does not apply.
Select materials for the protective conductor terminal that are not likely to be susceptible to electrochemical corrosion. Appropriate measures must be taken to protect protective earth conductors against mechanical, electro- dynamic, and thermodynamic stress. Mechanical protective earth connections must be accessible for inspection and testing.
