The motor must be wired up in
accordance with the motor manufacturer's
INSTRUCTIONS (normally supplied within the
terminal box), including any temperature, earth
leakage, current, and other protective devices as
appropriate. The identification nameplate should be
checked to ensure the power supply is appropriate.
4.6.3 Emergency stopping
A device to provide emergency stopping shall
be fitted.
4.6.4 Rotation direction
Check required direction of rotation
