Elektrische Installation¶
WARNING!
- Risk of electric shock
- Risk of electric arcs
- Risk of injury
- Risk of component destruction
Always turn off the power supply before disconnecting or making electrical connections in the system. Secure the power supply against reconnection. After switching off, wait at least 5 minutes for the capacitors to discharge. Check the absence of voltage before working in the system. Occurrence of arcs in the case of electrical connections that are not installed properly. Cables connected to i.Cee:plus II must not have exposed and stripped wire ends. Also, ensure that all connections are securely seated.
CAUTION!
The terminals are designed for single wires only.
Due to improper multiple occupancy, a fixed connection cannot be guaranteed. There is a risk that wires can slip out of the terminals and cause short circuits.
If several signals/wires have to be connected to a connection terminal, they must be merged via an external terminal and connected from there with a single wire.
Auswahl of Power Supply¶
Information on the correct dimensioning of the voltage source can be found in the technical data. To connect these, use the pins to X1. A Zeichnung where these can be found can be found under 4.2.2 (p.9).

| Supplement switchgear such as contactors, relays or solenoid valves with interference suppression combination or spark extinguishing elements (e.g. diodes, varistors, RC links). |
Reduce mutual interference coupling. |
|
| Wiring |
Keep cables/connections as short as possible |
Avoiding capacitive and inductive interference |
| Do not lay sensor cables and signal cables together with cables for DC and AC voltage above 60 V in a cable duct. |
