Annex 4
Information about cable glands approved for explosion protection
The terminal boxes are designed as standard with metric threaded holes in accordance with IEC/EN 62444
or as a special version with NPT threaded holes according to ANSI B1.20.1-1983. On delivery, they are
sealed with plugs or ATEX-certified cable glands.
For connection of the machine, only cable glands, cable entries and sealing plugs which are designed ac-
cording to Directive 2014/34/EU and have a minimum protection class of IP 55 or match the protection class
of the motor must be used.
For motors with i
gnition protection type “tD”, which require protection class IP 6X, the cable glands and plugs
must be designed according to Directive 2014/34/EU and have a minimum protection class of IP 65.
All unused cable entry openings must be sealed with plugs of the appropriate minimum protection
class approved according to Directive 2014/34/EU. Existing plugs must be checked for compliance
with this specification and replaced if necessary.
The thread type is indicated on the equipment (rating plate or terminal box).
Alternatively, the number and position of the entry threads are indicated on the dimension drawing of the mo-
tor. Unless otherwise ordered, cable glands from Jacob or Hawke are used internationally. The following
specifications must be observed for these screw connections:
