ControlMaster CM15
Universal process indicator

4.5 Electrical Connections

Warning.

The indicator 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 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 disconnection
device for the indicator.

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 terminals accept cables from 18 to 14 AWG (0.8 to 2.5mm

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 – 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 indicator'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.).
