Terminal Description Function
230V 1–Phase 460V 3–Phase
RLY1 Relay Output Normally open, programmable
contact for a relay output.
Contact closes when the programmed
condition (see Section 4) is true.
No voltage is present on this contact. 6
conditions are available.
TH1A Thermistor Connection to motor thermistor It is good practice to protect motors by using
thermistors. A typical resistance (up to a
reference temperature of 125_C) is 200Ω,
rising rapidly to 2000Ω above this temperature
