Hints for screwed cable glands that are admitted for
explosion protection
The terminal boxes are designed as standard with
metric threaded holes according to EN 50262 or on
request with NPT-threaded holes according to ANSI
B1.20.1-1983. At delivery the holes are closed with
plugs or ATEX-certified cable glands. For connection
of the motor only use cable entries that are designed
according to directive 2014/34/EU (RL94/9/EC) and
have at least IP 55 type of protection.
For motors in type of protection flameproof enclosure “t”
(IP 6X necessary!) the cable entries and plugs must be
designed according to directive 2014/34/EU (RL94/9/EC)
(ATEX) and have at least IP 65 type of protection.
All unused cable entry points must be closed
with plugs according to the minimum type of
protection listed in directive 2014/34/EU
(RL94/9/EC) (ATEX). Existing plugs must be
checked accordingly and if necessary they
have to be changed.
The specification of thread type is given on the
equipment (name plate or terminal box). Alternatively
the instruction about cable entry thread, number and
position of cable entries can be given in the dimensional
drawing of the motor. For explosion protected VEM-
motors cable glands of the company Jacob are used, if
not ordered otherwise. The following specifications must
be observed for these special cable glands:
