Induction heater JH1500
The placing of the safety sign
The safety sign is placed on the back of the
JH1500, as in the picture.
Safety devices
When the induction heater is in use, the
inductor, cables, electronics and transformer
can frequently become very hot. To protect
the induction heater from overheating, it is
cooled continuously when in operation. The
induction heater is cooled all the time by
water that circulates through the inductor. The
water begins to circulate when the machine is
started. A sensor detects the water flow and
trips the induction heater if the flow is blocked.
The JH1500 must be connected to earth.
It has an inbuilt residual current breaker to
protect the user in case of a ground fault. It
also has an automatic fuse, which trips if the
current exceeds 32 A (for JH1500‑400V) or
63 A (for JH1500‑200V).
In case the JH15000 would get overheated,
the overheating protection automatically
disables the heating function to protect the
machine and its electronic parts. However, the
cooling system continues to cool the machine
to make it ready for operation again.
The inductor handle is insulated to protect the
user from electric shocks.
