Page 12: Safety Considerations
Installing the Controller Locate your controller as far as possible from power lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and AC motor drives. For more information on proper grounding guidelines, see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1. -

Installing the Controller Use only the following communication cables in Class I, Division 2 hazardous locations. Communication Cables for Class I, Division 2 Hazardous Locations Description Catalog No. This 3.96 m (12 ft) cable has two 9-pin DTE connectors and is used 1747-CP3 to connect the RS232 channel (Channel 1 or 2) on the DataSite controller to a serial port on a personal computer. -
Page 14: Disconnecting Main Power
Installing the Controller Disconnecting Main Power Explosion Hazard WARNING Do not replace components, connect equipment, or disconnect equipment unless power has been switched off. The main power disconnect switch should be located where operators and maintenance personnel have quick and easy access to it. In addition to disconnecting electrical power, all other sources of power (pneumatic and hydraulic) should be de-energized before working on a machine or process controlled by a controller. -
Page 15: Power Distribution
Installing the Controller Power Distribution There are some points about power distribution that you should know: • The master control relay must be able to inhibit all machine motion by removing power to the machine I/O devices when the relay is de-energized. -
Page 16: Input States On Power Down
Installing the Controller Input States on Power Down The power supply hold-up time as described above is generally longer than the turn-on and turn-off times of the inputs. Because of this, the input state change from On to Off that occurs when power is removed may be recorded by the processor before the power supply shuts down the system. -
Page 17: Master Control Relay
Installing the Controller Master Control Relay A hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens, the master control relay is de-energized. -

Page 26: Using Surge Suppressors
Wiring the Controller Screw-cage clamp terminal block 44756 Using Surge Suppressors Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type of surge suppression to protect and extend the operating life of the controllers output field effect transistors (FETs) or contacts is required. - Page 27 Wiring the Controller If the outputs are DC, we recommend that you use an 1N4004 diode for surge suppression, as shown below. For inductive DC load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge suppressor can also be used.

The field connection can be divided into two-wire system and three-wire system. There are two types of adjustable input ranges for analog inputs, 0…10V for the 1758-FLO301 and 1758-RTU201 controllers, and 4…20 mA for the 1758-FLO302 and 1758-RTU202 controllers. -
Page 32: Minimizing Electrical Noise On Analog Channels
Wiring the Controller Minimizing Electrical Noise on Analog Channels Inputs on analog channels employ digital high-frequency filters that significantly reduce the effects of electrical noise on input signals.
