9. Electrical connections
Observe all local regulations (e.g. VDE 0100
"Conditions for installing heavy current plant with
rated voltages lower than 1000 volts" in Germany)
when selecting the type of electrical cable and
installing them!
In the case of "intrinsically safe" explosion-proof
versions [EEx ia] IIC, the supplementary informa-
tion given on the type examination certification, the
EN 60 079-14, and also local regulations appli-
cable to electrical installation in explosion hazard
areas must be taken into account.
Notes ...,
..., the electrical data marked on the nameplate of the SINEAX
VC 603 must correspond to those of the plant (measured
variable input
, output signal
and output contacts, Fig. 9).
..., the terminals are suitable for wire gauges up to a maximum
of 1 ×2.5 mm
.
2
..., twisted cores must be use for the measured variable input
and output leads and routed as far away as possible from
power cables.
