4. TECHNICAL SPECIFICATIONS
Designed for cooling or heating application. MT-512e Log is equipped with 1 powerful 2HP relay, 1
temperature sensor, 1 digital input, data logger, cyclic time for natural defrost, IP65 frontal, min-max
temperature record, sensor response time control, fast freezing mode, tamper-proof function, control
functions shutdown and RS485 serial communication port for Sitrad real-time monitoring and
management.
Product conforming to UL Inc. (United States and Canada).
- Check the controller for correct assembling;
- Make sure that the power supply is off and that it is not turned on during the controller installation;
- Read the present manual before installing and using the controller;
- Use adequate Personal Protective Equipmenet (PPE);
- For application at sites subject to water spills, such as refrigerated cabinets, install the protecting vinyl
supplied with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we make
available as an optional item (sold separately);
- The installation procedures should be performed by a qualified technician.

6.2. Temperature sensor connection
- Connect the sensor wires to terminals ‘1 and 2’: the polarity is not relevant.
- Length of the sensor cables can be increased by user himself to up to 200 meters, using a PP 2x24
AWG cable.
- For immersion in water, use a thermowell (Image VI - item 13), available in the Full Gauge Controls
product line (sold separately).
