SolConeX Flange Socket, 20 A
Series 8570/25
7.2 Mounting / Dismounting, Operating Position
7.2.1 Mounting
The switched flange socket 8570/25 is intended to be mounted on an Ex e enclosure
(metal or plastic). Therefore, the following installation requirements have to be met:
Wall thickness of the enclosure
See chapter 7.1.
Thickness range of the enclosure
Metall enclosure: 1.5 to 3.0 mm / 0.059 to 0.118 inch
Plastic enclosure: 2.2 to 3.5 mm / 0.087 to 0.138 inch
Maximum surface roughness of the enclosure face for sealing
Metall enclosure: Rq = ca. 0.43 µm / Ra = ca. 0.38 µm
Plastic enclosure: Rz = ca. 7.2 µm
Mounting auxiliary contacts
This device is suitable for outdoor and indoor use.
The sealing of the device ensure the IP protection.
For mounting instructions for installing the auxiliary contacts,
see installation note 8570/8571 (8570607300).
11203E00
• Open the enclosure.
• Snap the auxiliary
contacts into place
optionally in the left-hand
or right-hand seat.
Double equipping is
possible.
• Close the enclosure.

7.3 Installation
DANGER
Explosion hazard due to insufficient protective measures!
Non-compliance results in severe or fatal injuries.
• Select suitable cables to ensure that the maximum
permissible conductor temperatures are not exceeded.
• Lay cables in intrinsically safe circuit separately to cables in
non-intrinsically-safe circuits. The distance measurements for
this can be found in the "Separating intrinsically safe circuits
from non-intrinsically-safe circuits" section.
• When using core end sleeves, attach them using a suitable tool.
• Use only separately tested cable entries and stopping plugs
with an US Type Examination Certificate.
• The conductor insulation must be touching the terminal.
• Do not damage the conductor (for example nicking)
when stripping it.
• Always connect the protective conductor.
DANGER
Explosion hazard in the case of installation in special areas with
potentially explosive dust!
Non-compliance results in severe or fatal injuries.
• Do not use the device in areas where there are processes
generating strong charges, machine friction processes,
separation processes and electrospray processes
(for example around electrostatic coating systems)
and pneumatically generated dust.
DANGER
Explosion hazard when seal is insufficient and/or service temperature
is too high!
Non-compliance results in severe or fatal injuries.
• Completely seal the bayonet ring of the plug and of the hinged
cover to obtain the degree of protection.
• Securely seal and lock the enclosure.
• Make sure the service temperature range is maintained
(see the "Technical data" chapter).
