Hach sc1000 User Manual

If installed outdoors, provide overvoltage protection between the power and the sc1000 
controller. Make sure the data and power cables do not cause tripping and do not contain 
any sharp bends. Refer to 

 for housing breakout information. 

High-voltage wiring for the controller is conducted behind the high voltage barrier in the 
controller enclosure. The barrier must remain in place unless a qualified installation 
technician is installing wiring for power, alarms, or relays. See 

 for barrier 

removal information.

The instrument can be wired for line power by hard-wiring in conduit or by wiring to a 
power cord if allowed by local electrical code. A local disconnect designed to meet local 
electrical code is required and must be identified for all types of installation. 

Do not connect the electrical power supply to the AC power until the sc1000 controller 
has been fully wired, fused, and the high voltage barrier and probe module cover have 
been replaced.

In hard-wired electrical applications, the power and safety ground service drops for the 
instrument must be 18 to 12 AWG. A sealing-type strain relief must be used to maintain 
the IP65 environmental rating. See 

 for strain relief and conduit opening sealing 

plug assembly. See 

 for wiring information.
