Installation
The mains power cord for 115 VAC samplers is equipped with a
NEMA 5 15P plug for standard North American outlets. The mains
power cord for 230 VAC samplers is equipped with an EU 1-16P
plug for standard CEE-7/7 European outlets. If you have other
types of outlets that supply compatible AC power, contact a trained
electrical technician to connect the power cord with a
locally-purchased plug, in accordance with the local safety
requirements.
All AC mains power connections require a 15 A (max) circuit
breaker and a good earth ground for safety and performance.
1. Check the power source to make sure that it satisfies the AC
power requirements of the sampler.
2. Make sure that all electrical installations and connections are in
accordance with national and local electrical codes.
3. Before performing any connection, disconnect the sampler
from the power source.
4. If the area is wet or hands or clothing are wet, do not attempt to
make any connection or handle the electrical components of
the sampler when connected to AC line power.
5. If the circuit breaker or fuse in the AC power source is tripped,
determine the cause before restoring power to the sampler.
6. Make sure the power circuit is grounded and protected with a
Ground Fault Interrupter (GFI).
3.5.2 Flow meter installation
The sampler can be connected to a flow meter to start or stop
sampling based on the flow volume.
Prerequisites:
• Multi-purpose full cable for Sigma flow meters (or 980 half
cable for the model 980 flow meter). To connect to another
brand of flow meter, use a multi-purpose half cable and follow
the wiring instructions in
Appendix A on page 99 .
• Optional splitter ( Figure 22 ) to provide additional connections.
Two or more splitters may be connected in series.
Note: See Accessories on page 94 for ordering information.
Installation procedure:
1. Connect one end of the cable to the flow meter. For connection
to the model 980 flow meter, follow the instructions in the model
980 user manual.
2. Connect the other end of the cable to the controller.
Note: For connection to a flow meter with an existing 6-pin cable, use
the auxiliary adapter cable (6-pin to 7-pin adapter)
