ControlMaster CM15 and CMF160Universal process indicator 1 /8 DIN 4 Installation20 IM/CM/I–EN Rev. P4.5 Electrical ConnectionsWarning. The controller is not fitted with a switch therefore a disconnecting device such as a switch or circuit breaker conforming to local safety standards must be fitted tothe final installation. The switch must be mounted in close proximity to the controller within easy reach of the operator and must be marked clearly as the disconnection device for thecontroller. Remove all power from supply, relay and any powered control circuits and high common mode voltages before accessing or making any connections. Use cable appropriate for the load currents. The CM15 terminals accept cables from 18 to 14 AWG (0.8 to 2.5mm2 ). The CMF160 terminals accept cables from26 to 14 AWG (0.14 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. For I/P lead lengths greater than 30 m (98.4 ft.) screened cables must be used. The instruments conform to Mains Power Input Overvoltage Category 2, Pollution Degree 2 (EN601010–1).(The CM15 equipment is protected through double insulation – Insulation Class 2.) CMF160 Insulation Class 1. 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, for example terminals. Terminals for external circuits are for use with equipment with no accessible live parts only. 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).CM15, CMF160 Indicators – USA and Canada Only The supplied cable glands are provided for the connection of signal input and ethernet communication wiring ONLY. The supplied cable glands and use of cable / flexible cord for connection of the mains power source to the mains input and relay contact output terminals is notpermitted in the USA or Canada. For connection to mains (the mains input and relay contact outputs), use only suitably rated field wiring insulated copper conductors rated min. 300 V, 14 AWG, 90C.Route wires through suitably rated flexible conduits and fittings.Note. The CM15 terminal screws must be tightened to a torque of 0.1 Nm (0.9 lbf.in.). The CMF160 terminal screws must be tightened to a torque of 0.5 to 0.6 Nm(4.42 to 5.31 lbf.in.)
