Safety Precautions
EJM9BE-SF-01N-21 Page S-7
Observe the following precautions in handling linear motors.
Magnetic force may cause injuries and accidents. It may also cause burns.
z
NPM uses linear motors for driving along its X- and Y-axes.
z
Since extremely powerful permanent magnets are used in the linear motors, wrong handling can be
extremely dangerous even if the main power supply is in the OFF state.
In working inside the safety covers (e.g. in maintenance), follow the rules below.
1. Those who wear pacemakers must not work inside the safety covers.
2. In working, do not wear any metals such as watches, pierced earrings, and necklaces.
3. Since the movers of linear motors become hot (80°C under 25°C environment, 90°C under 35°C
environment), take care not to suffer burns.
z
After shutdown, it may be three hours or more before they reach room temperature.
4. Do not disassemble the linear motors.
z
Since the attractive power of the stators (the magnets) is extremely powerful, disassembling
them can be extremely dangerous.

Do not put your hands in the openings between feeders installed.
Your hands may be injured by the moving parts in the machine.
z
We recommend installing all feeders so that you will not accidentally put your hands into the machine.

In maintenance, be careful not to receive an electric shock.
Even if the main power supply switch is OFF in maintenance, the power is still supplied as
far as its primary line; therefore, you may receive an electric shock.
