9 The open frame design of the dct1000dc will require an enclosure that Note: If a DCP100A or DCP200A pressure module is installed in the meets appropriate safety and local code requirements. For optimal master controller , the switching functions are ignored. performance, the enclosure should also protect the controller from dirt, water and direct sunlight. There are no special orientation requirements, and the controller mounts easily using the mounting holes on the factory installed base plate. Caution: Do not run control wires, communication cables, or other class 2 wiring in the same conduit as power leads. The system may malfunction if class 2 wiring is run together with power conductors. Power Requirements The dct1000dc requires 10 to 30 VDC supply power. The solenoids must be matched to supply voltage.

10 DO NOT exceed 35V, because transient suppression circuitry will begin to draw high current. E-97DC : E-97DC 10/5/10 8:27 AM Page 4. NORMALLY OPEN CONTRACTS. LOW. LIMIT. PRESSURE HIGH. LIMIT LIMIT.
