ControlMaster CM10, CM30 and CM50Universal process controllers, 1/ 8 , 1/ 4 and 1 /2 DIN 4 Installation14 IM/CM/S–EN Rev. R4.5 Electrical ConnectionsWarning. The controller is not fitted with a switch therefore a disconnecting device such as a switch or circuit breaker conforming to local safetystandards must be fitted to the final installation. It must be mounted in close proximity to the controller within easy reach of the operator and must be marked clearly as the disconnectiondevice for the instrument. Remove all power from supply, relay and any powered control circuits and high common mode voltages before accessing or making anyconnections. Use cable appropriate for the load currents. The terminals accept cables from 18 to 14 AWG (0.8 to 2.5mm2 ). Always route signal leads and power cables separately, preferably in earthed (grounded) metal conduit. It is strongly recommended that screened cable is used for signal inputs and relay connections. The instrument conforms to Mains Power Input Overvoltage Category 2, Pollution Degree 2 (EN601010–1).(This equipment is protected through double insulation – Insulation Class II.) Analog / digital inputs and outputs, transmitter power supply and DC power supply are SELV (Safety Extra Low Voltage) circuits. All connections to secondary circuits must have basic insulation. After installation, there must be no access to live parts, e.g. terminals. Terminals for external circuits are for use only with equipment with no accessible live parts. If the controller is used in a manner not specified by the Company, the protection provided by the equipment may be impaired. All equipment connected to the controller's terminals must comply with local safety standards (IEC 60950, EN601010–1).Note. Terminal screws must be tightened to a torque of 0.1 Nm (0.9 lbf/in.).
