Installation instructions

ATEX / IECEx

The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel. Works may be
= 30 V
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.
= 6.5 V
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.

Devices with type of protection 'Ex d' with cable glands
If devices in 'Ex d – flameproof (enclosure)' type of protection
with cable gland are ordered, an Ex d certified cable gland is
factory-installed.
Cable gland data
• Thread: 2 × M20 × 1.5 or 2 × ½ in NPT
• Temperature range: −50 to 85 °C (−58 to 185 °F)
• Cable outside diameter: 3.2 to 8.7 mm (0.13 to 0.34 in)
• Material: nickel-plated brass
The cable entry is only suitable for fixed installations and non-
reinforced cables with round and smooth plastic sleeves and
suitable outside diameter. The cables must be attached
appropriately in order to prevent them being pulled out or
twisted.
The operating instruction and approvals supplied with the cable
glands, as well as any applicable requirements in accordance
with EN 60079-14 must be taken into account accordingly.
