6.1 Safety
6.1.1 Notes on electrical installation
Connection work
•
Electrical installation must only be performed by electrically qualified personnel.
•
Standard safety requirements must be observed when working on electrical sys‐
tems!
•
All connection work must be performed at ambient temperatures above 0 °C, see
"Ambient data", page 63
•
Electrical connections between the device and other devices may only be made or
separated in a voltage-free state. Otherwise, there is a risk of damaging the
devices.
•
Where connecting cables with one end open are concerned, make sure that bare
wire ends are not touching (risk of short circuit when the supply voltage is switched
on). Wires must be appropriately insulated from each other. This also applies to
unused wires.
•
The wire cross-sections of the data and, if applicable, switching signal cables must
be selected in accordance with the applicable national standards.
NOTE
For additional instructions on operating the device at ambient temperatures below
0 °C, see "Prerequisites", page 40
Supply voltage
•
Connect the device only to the permissible supply voltage, see "Connecting the
supply voltage", page 43
•
The wire cross-sections in the supply cable from the user’s power system must be
selected in accordance with the applicable national standards. When this is being
done in Germany, observe the following standards: DIN VDE 0100 (Part 430) and
DIN VDE 0298 (Part 4) and/or DIN VDE 0891 (Part 1).
•
All circuits connected to the device must be designed as ES1 circuits. The voltage
supply or power supply unit must satisfy ES1 requirements in accordance with the
currently applicable EN 62368-1, see "Mechanics and electronics", page 62.
•
Only switch on the supply voltage to the device , after first:
°
Completing the connection work
°
Carefully checking the wiring work
