Connecting Power

The M1500 monitor is powered from 100-240 VAC, 50/60 Hz or optionally from 24 VDC. Damage will occur if 100-240 VAC power is connected to an M1500 equipped with the 24 VDC input power option. M1500’s equipped with the 24 VDC option will have a “-24” suffix in their model number such as M1500-24 or M1500T-24.

Because the M1500 is UL 1604 listed for Hazardous Location use, (Class I Division2, Groups A, B, C, D; Class II Division 2 Groups F and G: Temperature Code T4A), it has no power switch for switching off supplied power. Please read the functional description of the POWER button on page 12. Consideration should be give to the installation of an appropriately rated external power switch if the application requires powering off the M1500.

Power is connected to the M1500 through a removable Phoenix Contact plug (Phoenix Contact P.N. 1777992) that allows for screw termination of field wiring. The use of 18 AWG or greater (12 AWG maximum) is recommended. Connect the field wiring according to the appropriate table below. After the connections are made, make sure the plug retention screws (the two screws shown in the “Front View” below) are securely tightened. This will prevent the plug from pulling out.
