and 4221)
Special Conditions for Safe Use
This equipment is intrinsically safe and can be used
in potentially explosive atmospheres.
The apparatus mus only be connected to a certified
associated intrinsically safe equipment and this
combination must be compatible as regards intrinsic
safety rules.
The electrical parameters of the associated
intrinsically safe equipment must not exceed any of
the following values:
Uo
30 V, lo 150mA, Po 1W
Maximal ambient temperature:
−
40

Refer to table 7 for approval information, and figure
27 for ATEX approval nameplates.
Mechanical Connections
Sliding-Stem Actuator Mounting,
Type 4210, 4211, 4212, and 4215
Use the following general procedures and figures 15,
16, 17, and 18 to mount the transmitter on
sliding-stem actuators, standard stroke up to 105
mm (4.125 inches) travel.
Refer to figure 15 for key number locations for this
example.
1. Install the transmitter on the mounting plate
(key 21) with two cap screws (key 32).
2. Bolt the stem mounting bracket and spacer
(keys 34 and 39) to the stem connector on the
