Installation and electrical connection
NOTICE
The radial deviation of the two coupling halves must not exceed the maximum val-
ues found in table "Maximum permissible shaft displacement ΔS
This requirement applies to every operating status – including operating temper-
ature and inlet pressure.
Checking the axial alignment
NOTICE
The axial deviation of the two coupling halves must not exceed the maximum values
found in table "Permissible gaps S and S2". This requirement applies to every oper-
ating status – including operating temperature and inlet pressure.
Using a calliper gauge, circumferentially check the distance between the two coupling
halves.
ƒ
Connect the coupling halves once correctly aligned.
The tightening torques for the coupling are listed in the table "Tightening torques
for adjusting screws and coupling halves".
ƒ
Install the coupling guard.
