3.7 System Wiring
Refer to the certified electrical drawing(s) for specific wiring requirements. As explained in Paragraph 4.1.9.9, the
20-position barrier terminal strip on the circuit board mounted INSIDE the controller enclosure is the connection
point for ALL external circuitry.
The controller was completely assembled and tested with the sampler before it left the factory. The electrical
installation must comply with OSHA Regulations; the National Electrical Code; and all other applicable federal,
state, and local codes and regulations.
If wiring between the controller and the sampler unit is run through rigid conduit, use a short length of flexible
conduit to connect wiring to the sampler. This will isolate the rigid conduit from any vibration originating in the
product conveying line and sampler.
3.7.1 Electrical Power Requirements, System
110/120 VAC 50/60 Hz, Single Phase, 15 Amp Service.
Optional - 220/240 VAC 50/60 Hz, Single Phase, 10 Amp Service.
Refer to the certified electrical drawing(s) for specific wiring requirements. Inter
s
ystems strongly recommends
that electrical service to the sampling system be an isolated line. Voltage fluctuations and line noise can affect the
controller's circuit board, thus causing the sampler to malfunction.
