Electrical connections
Please observe the following for correct operation:
●
Provide a disconnector unit in the building installation.
●
Connect the enclosure of the analyzer to the equipotential bonding (see also associated operating instructions or product
manual).
●
Use solid or stranded cables with a cross-section of not more than 2.5 mm² for wiring the terminals.
●
Provide all stranded conductors with end sleeves.
●
Keep all connection cables within the analyzer short.
●
Identify the intrinsically-safe lines and route them separately from the non-intrinsically-safe lines. Observe the minimum
distances required when doing this.
●
Connect the power and signal cables according to the terminal wiring diagrams of the devices to be connected (see the
associated operating instructions or product manuals).
●
Be particularly careful with the cable inlets (cable glands). Use sealing rings corresponding to the cable diameters for the
cable glands.
Cable diameter ranges and torques M for the screwed glands:
–
M 20 power cable/RS485:
∅
Cable: 7 ... 12 mm; M = 3.8 ± 0.2 Nm
–
M 20 signal cables: ∅ Cable: 10
... 14 mm; M = 3.8 ± 0.2 Nm
