Mounting and start-up
Equipment with type of protection ExnA
In equipment operated according to type of
protectionExnA(non-sparkingequipment),
circuits may be connected, interrupted or
switched while energized only during instal-
lation, maintenance or repair.
Certiedcableglandsandblankingplugs
with appropriate type of protection with an
IPrating≥6Xandsuitableforthecertied
temperature range must be used.
The signal circuit is connected using screw
terminals(terminal11/12)forelectricalcon-
ductors with a wire cross-section from 0.2 to
2.5mm².Thetighteningtorqueis0.5to
0.6Nm.
Equipment with type of protection Ext
In equipment operated according to type of
protectionExt(protectionbyenclosure),cir-
cuits may be connected, interrupted or
switched while energized only during instal-
lation, maintenance or repair.
Opening the enclosure cover in potentially
explosive dust atmospheres during operation
may cause the explosion protection to be-
come ineffective.

5.14.1 Cable entry with cable
gland
The housing of the TROVIS3730-1 Position-
er has two threaded boreholes, which can
bettedwithcableglandsasrequired.
Î The cable gland version depends on the
ambient temperature range. See techni-
caldatainsection3.7onpage23.
Î The screw terminals are designed for
wirecross-sectionsof0.2to2.5mm²
(tighteningtorque0.5Nm).
Î Connect one current source at the maxi-
mum.
In general, it is not necessary to connect the
positioner to a bonding conductor. Should
this be required, however, this conductor can
be connected inside or outside of the device
(seeFig.2onpage17).
