Mounting
The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel. Works may be
carried out only by persons, whose training has included
instructions on different types of protection and installation
techniques, concerned rules and regulations as well as general
principles of zoning. The person must possess the appropriate
competences for the type of work to be conducted.
When operating with combustible dusts, comply with
EN 60079-31.
The safety instructions for electrical apparatus in potentially
explosive areas must be in accordance with Directive
2014/34/EU (ATEX) and IEC 60079-14 (Installation of electrical
equipment in potentially explosive areas).
Comply with the applicable regulations for the protection of
employees to ensure safe operation.

Cable gland
Limited temperature range of the M20 × 1.5 plastic cable gland
for explosion protection variants.
The permissible ambient temperature range of the cable gland is
Æ
20 to 80 °C (
Æ
4 to 176 °F). When using the cable gland, make
sure that the ambient temperature is within this range. The
cable gland must be installed in the housing with a tightening
torque of 3.8 Nm. When installing the connection of the cable
gland and cable, check for tightness to ensure that the required
IP rating is met.
