5.2.2 Wiring Power and Signal Terminals
Figure 9 below show the typical mains (for both 230 and 115 Volts systems) and the 4-20mA signal
connections in BioTector. The connection to mains power {230V or 115V AC ( ± 10%), 50/60 Hz} should be
carried out by a certified electrician, in accordance with site regulations. The mains wire specifications are 3
cores, 10 Amps minimum current rating and 1.50mm
2
minimum CSA (Cross Sectional Area). The mains cable
should be screened and screen earthed to comply with the Electromagnetic Compatibility Directive
(2004/108/EC).
For 4-20mA and any other signal connections, only screened instrument cable, which comply with the EEC
directive, should be used. The signal cable should also be screened, and the screen earthed. The
specifications for the signal wire are 6 cores (+2 cores per additional signal), 1 Amp minimum current rating,
0.22mm
2
minimum CSA (Cross Sectional Area).
BioTector contains electrical components operating under high voltages. Contact
may result in electric shock and severe or fatal injury.
The equipment is for permanent connection to the mains only. (Plug and socket
should not be used.)
