Note:

1. EH- and EHN-series models are provided with a CT incorporating 30- or 100-cm-long lead wires and Power Device Cartridge.

When ordering, specify the length of the lead wires by adding a code to the model number as shown below.
G3PX-2

0EH-CT03: CT with 30-cm-long lead wires

G3PX-2

0EH-CT10: CT with 100-cm-long lead wires

2. Adjusts the multiple heater burnout detection sensitivity of EHN-series models. Enables single heater burnout detection in control of

a maximum of five heaters.

3. When ordering, Rated voltage should be made sure if it is for 200/230 VAC. Otherwise 200/220 VAC G3PX is existing.
