3.0 Electrical Installation
The model 730 operates from a 12-30 VDC regulated power supply for
the 0-10 VDC output version or from a 9-30 VDC regulated power supply
for the 0-5 VDC output version. Either version can be specified with a 5 Pin
terminal strip, 9 Pin D-sub, or 15 Pin D-sub on a 6 inch pigtail. Mating con-
nectors are provided with the terminal strip version. The pinouts for each
option are shown in figures 4, 5, and 6, Page 6.
The ground of any external power supply and readout system should be
the same as the transducer ground (chassis ground) to minimize any pos-
sible ground loops, which may effect the performance and stability of the
system.
3.1 Wiring Guidelines
The Model 730 is compliant with the Electro Magnetic Compatibility Direc-
tive 2004/108 EC, which tests for radio frequency emissions and immunity,
provided the following wiring guidelines are adhered to:
1. All interconnecting cables must have overall metal braid and foil
shields covering all wires and be properly grounded at each end.
2. The cable connectors must have a metal case and it must be in
direct contact with the cable braided shield for the entire circumference of
the cable. A single wire from the shield to the connector case will not be
effective.
3. The connectors must make good contact, about 0.01 ohms, to the
transducer’s case (chassis).
4. Versions with the 5 pin terminal strip connector option must be
used with a suitable clamp on ferrite such as the Fair-rite part number
0461164281 which is included with each unit. The ferrite should be assem-
bled as close to the connector as possible to meet CE EMI requirements.
