1. Preparation before installation
Selection confirmation:
Check the current load capacity of the thermostat again to match the actual application load to ensure that the thermostat will not be damaged due to overload.
Ensure that the operating voltage range of the thermostat is consistent with the actual power supply system.
Tools and materials:
Prepare proper installation tools, such as screwdrivers, wrenches, and wire strippers.
Prepare required connection materials, such as wires and wiring terminals.
Second, during the installation process
Installation location selection:
The temperature controller should be installed in a well-ventilated, dry, non-corrosive gas and away from heat sources. Avoid installation in direct sunlight, damp or vibration prone places.
Ensure that the installation position is easy to operate and observe for future temperature adjustment and maintenance.
If it is installed in the electrical control cabinet, it is necessary to ensure that there is enough space for heat dissipation and avoid being too close to other heating components.
Wiring specification:
Strictly follow the wiring diagram of the thermostat to make sure that the connection is correct.
For high-current lines, wires with sufficient cross-sectional area should be used to reduce line resistance and heat.
The terminal must be securely secured to avoid loose contact or heat.
Distinguish the input and output lines, as well as the terminals of different functions, to prevent wrong connection.
Ground protection:
Ensure that the thermostat is reliably grounded to improve safety and anti-interference capability. The grounding resistance must meet the requirements of relevant standards.
Insulation treatment:
After the wiring is complete, insulate the exposed part of the wire and use insulation tape or heat shrink pipe to prevent short circuit and electric shock.
Third, check after installation
Appearance inspection:
Check whether the thermostat is firmly installed, without loosening or tilting.
Check that the shell is not damaged or deformed.
Electrical inspection:
Use tools such as a multimeter to check whether cables are correctly connected and whether there is short circuit or open circuit.
Measure the input and output voltage to ensure the stability of the thermostat power supply.
Functional test:
After the installation is completed, a preliminary functional test is carried out, and different temperature values are set to observe whether the thermostat can normally control the load on or off.
Check whether the temperature display of the thermostat is accurate and consistent with the actual temperature.
Safety protection:
Set up necessary protective measures around the thermostat, such as guardrail, warning signs, etc., to prevent personnel from touching or accidents.
