Lack of leak-tightness (impairment of IP protection)
The IP degree of protection identifies how equipment must be sealed according to
regulations.
Making structural modifications, e.g. drilled holes, or improper mounting can impair the
device's IP protection. This may result in explosions causing serious or fatal injuries to
persons.
 Only drill holes for cable entries exactly according to the instructions in the
"Product selection, project engineering and modification" and "Mounting" chapters of
these operating instructions. Consult with R: STAHL first if there are any discrepancies or
uncertainties.
 Install the device only in the prescribed mounting position. More detailed explanations of
this can be found in the "Mounting" chapter.
 Conduit entries may be field installed in these enclosures per the instructions in
chapter 6.2.1.
 For a Class I, Zone 1 conduit installation, conduit seals are required, refer to
NEC 505.16 (B) (1). For any other cable or conduit installation NO seals are required.
 Use only approved wiring methods for the location, with the associate cable/conduit
fittings. Reference your local code.
Improper installation, commissioning and maintenance
The work listed above may only be performed in accordance with the current national
regulations of the country of use. Otherwise, the explosion protection may be rendered
ineffective. This may result in explosions causing serious or fatal injuries to persons.
To prevent this, comply with the following safety measures:
 Have mounting, installation, commissioning and maintenance performed only by qualified
and authorised persons (see Chapter 3.2).
 Only make modifications to the device in accordance with the directions in these operating
instructions. Have R. STAHL or a certified test body (third-party inspection) carry out
acceptance testing on any modifications made.
 Perform maintenance and repairs on the device only using original spare parts.
Consult R. STAHL beforehand.
