Install
the instrument in a dry place, away from heat sources at
a maximum room temperature of 40°C.
Comply with standards in force in the different countries
regarding electrical installation (Fig. 2).
If the power cord does not
have a plug, the device must be connected to the mains by
means of an omnipolar disconnecting switch with at least 3
mm between the contacts. All the power supply circuits must
be interrupted before accessing the connection devices
