ENMG / CABINET ENVIRONMENT
ETH60
Digital anti-condensation controller
A compact temperature and humidity controller for electrical cabinets, with an internal sensor and relay output for an external resistive heater. Heating starts when temperature is low or humidity is high and stops once both return within the reset thresholds.

Selection & installation notes
- Use resistive heaters only, within both 400 W and the relay rating; do not connect motors or contactor coils directly.
- Thresholds are factory-set and not user-adjustable. Request specified settings for custom orders.
- Connect supply to the top terminals and load to the bottom terminals according to the unit label. Mount vertically and keep the internal sensor away from direct heater airflow.
- The source describes forced-test lamp behaviour separately from normal fault indication. Confirm the test procedure before diagnosing an open load.
- Avoid condensation, ice, corrosive gases, strong vibration and electromagnetic interference. Isolate power before wiring.
