4.2.6.1 Installation instructions for side-mounted braking resistors
Fire risk without monitoring!
► The operation without external wiring for the monitoring of the
braking resistor is only permitted with an intrinsically safe braking
resistor!
Destruction of the frequency inverter if the vale has fallen below
the minimum brake resistance value!
► The minimum brake resistance value must not fall below!
Hot surfaces caused by load of the braking resistor!
burning of the skin!
► Cover hot surfaces safe-to-touch.
► Before touching, check the surface.
► If necessary, attach warning signs on the system.
