DANGER
Explosion hazard due to impermissible cable glands!
Non-compliance results in severe or fatal injuries.
• Use only cable glands approved for the required type of protection.
• When selecting cable glands, observe the thread type and thread size
in the equipment documentation.
• Make sure that the conductor diameter matches the clamping
cross-section of the cable glands.
DANGER
Explosion hazard due to incorrectly laid cables in the Ex e enclosure!
Non-compliance results in severe or fatal injuries.
• Adhere to the required creepage distances and clearances.
• Fasten mounting rails or elements properly.
DANGER
Explosion hazard due to cable glands without strain relief!
Non-compliance results in severe or fatal injuries.
• Lead cables and conductors securely.
• If the cables are laid loosely, use only cable entries approved for this
type of cable laying.
WARNING
Danger of electric shock due to energised parts!

Ex e terminal compartment.
To prevent condensation in the enclosure, we recommend using a breather,
type 8162 by R. STAHL Schaltgeräte GmbH.
By using a breather and depending on its mounting position, the degree of
protection acc. to IEC 60529 is reduced. If mounted lateral, the degree
of protection is IP64, if opening of breather is installed downwards, it is IP56.
