The power cord connection of the muffle furnace
The power cord connection of the muffle furnace:
1. The wire diameter of the user-supplied power cord should not be less than 6mm2, with an external 40A insurance.
2. For safety, the grounding wire must be connected to the ground near the laboratory and well grounded.
3. Connect the power cable of the muffle furnace to the air switch (or knife) of the power supply (AC220V±20V, 50Hz±1Hz), and check that the wire connection is correct, and there is no short circuit or open circuit.
4. Install the pallet, put the muffle furnace backing plate into the furnace body, and turn on the power. So far, the smart muffle furnace is installed.
