Connections
smaller than 0.1 mm. Protect the conductor
ends against splicing, e.g. by using wire-end
ferrules. When two separate cables or wires
are used for connection, an additional cable
gland can be installed. Seal cable entries left
unused with plugs. Fit equipment used in
ambient temperatures
below –20 °C
with
metal cable entries.
Equipment for use in zone 2/zone 22
In equipment operated according to type of
protection Ex nA II (non-sparking equipment)
according to EN 60079-15:2003, circuits
may be connected, interrupted or switched
while energized only during installation,
maintenance or repair.
Equipment connected to energy-limited cir-
cuits with type of protection Ex nL (ener
-
gy-limited equipment) according to
EN 60079-15: 2003 may be switched under
normal operating conditions.
The maximum permissible values specified
in the statement of conformity and its ad-
denda apply when interconnecting the
equipment with energy-limited circuits in
type of protection Ex nL IIC.
Cable entry
Cable entry with M20 x 1.5 cable gland.
See section on Actuator stem retracts FE (AIR
TO CLOSE) for clamping range.
There is a second M20 x 1.5 threaded hole
in the housing that can be used for addition-
al connection, when required.
The screw terminals are designed for wire
cross-sections of 0.2 to 2.5 mm². Tighten the
screws by 0.5 to 0.6 Nm.
The power supply for the positioner can be
supplied either over the connection to the
fieldbus segment or over a DC voltage
source (9 to 32 V) connected to the bus ter
-
minals in the positioner.
