Power Wiring with the ECY-PS100-240
Voltage
100-240 VAC; +10%/-15%; 50/60 Hz
Overvoltage Category II - 2.5 kV
For terminal block connector wiring best practices, see General Wiring Recommendations.
Always conform to the wiring regulations in effect in your jurisdiction.
Each ECY-PS100-240 power supply can supply a maximum of 40W to loads connected to the right of it, up to the next connected power supply. See the
ECLYPSE Selection Tool to calculate the number of Input/Output Extension Modules that can operate with each power supply, the number of power sup-
plies required, and their location. The total power consumption of all modules including external 18VDC loads (such as 0 to 20mA current loop inputs)
must be 40W or less.
The ECY-PS100-240 power supply must be connected to the mains using the provided detachable connector.
The power wires must be between 18 AWG (1 mm²) and 16 AWG (1.5 mm²). Use wire with appropriate insulation
for this application.
Operating, handling, or servicing this product must be performed by trained personnel only. Turn off power
before any kind of servicing.
Risk of electric shock. Do not open. This product has no user-serviceable parts inside. When power has been
disconnected, dangerous residual internal voltages may still be present. Return this unit to Distech Controls for
maintenance or repair.
