MOUNTING REQUIREMENTS

MOUNTING REQUIREMENTS MOUNTING REQUIREMENTS MOUNTING REQUIREMENTS MOUNTING REQUIREMENTS
These instruments are intended for permanent installation,
for indoor use only, in an electrical panel which encloses
the rear housing, exposed terminals and wiring on the
back.
Select a mounting location where the instrument is subject
to minimum vibration and the ambient temperature range
is between 0 and 50 °C.
These instruments can be mounted on a panel up to 15
mm thick with a square cutout of 45 x 92 (TKS) mm or
92 x92 (MKS) mm.
For outline and cutout dimensions refer to Fig. 2.
The surface texture of the panel must be better than
6,3 µm.
The instrument is shipped with rubber panel gasket.
To assure the IP65 and NEMA 4 protection, insert the
panel gasket between the instrument and the panel as
shown in fig. 1.
While holding the instrument against the panel proceed as
follows:
1 ) insert the gasket in the instrument case;
2 ) insert the instrument in the panel cutout;
3 ) pushing the instrument against the panel, insert the
mounting bracket;
4 ) with a screwdriver, turn the screws with a torque
between 0.3 and 0.4 Nm.

1 ) Don't run input wires together with power cables.
2 ) For TC wiring use proper compensating cable
preferable shielded.
3 ) when a shielded cable is used, it should be connected
at one point only.
