… 2 Use in potentially explosive atmospheres in accordance with
ATEX and IECEx
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
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 entries
Devices with type of protection ‘Ex d’ without supplied
cable glands
For devices with the ‘Ex d – flameproof (enclosure)’ type of
protection which are supplied without cable glands, observe the
instructions in Flameproof (enclosure) – Zone 1 on page 15.
For information on the cable gland used, refer to the relevant
data sheet and operating instructions.
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.
Installation instructions for cable glands
The sealing rings of the cable glands harden at low
temperatures. Before installation, bring the sealing rings to a
temperature of at least 20 °C for 24 hours. Before inserting the
sealing rings and fixing them onto the cable gland, knead the
rings to ensure they are soft and flexible.
IP rating IP66 / 67 is only achieved by installing the black
neoprene sealing ring between the cable gland and the housing
and by observing the tightening torque of 3.6 Nm (Figure 2,
item 2).
Cables must be protected against extreme mechanical loads
(caused by tension, torsion, crushing, and so on). Even under
operating conditions, it must be ensured that the cable entry
remains hermetically sealed. The customer must provide a strain
relief device for the cable.
A40 mm
B12 mm
CØ8.5 / 12 mm
Figure 1: Stripping the connection cable
1.Check that cable used is suitable (i.e., check the mechanical
resilience, temperature range, creep resistance, resistance to
chemicals, outside diameter, and so on).
2.Strip the cable in accordance with Figure 1.
3.Check the outer sleeve for damage and soiling.
4.Insert the cable in the cable gland.
Figure 2: Tighten cable glands
5.Tighten the cable gland until the cable is firmly enclosed by
the sealing ring (Figure 2, item 1). Do not tighten more than
1.5--times of the specified torque on the housing (see
assembly instructions for cable gland)!
