1.2 Residual hazards
Protection of persons
Before working on the controller, check that no voltage is applied to the power
ƒ
terminals:
– The power terminals U, V, W, +U
after disconnection from the mains.
– The power terminals L1, L2, L3; U, V, W, +U
stopped.
The leakage current to earth (PE) is > 3.5 mA. According to EN 50178
ƒ
– a fixed installation is required.
– a double PE connection is required or, if in single design, it must have a cable
cross-section of at least 10 mm
The heatsink of the controller has an operating temperature of > 80 °C:
ƒ
– Contact with the heatsink results in burns.
During parameter set transfer the control terminals of the controller can have
ƒ
undefined states.
– Therefore the plugs X5 and X6 must be disconnected from the controller before
the transfer takes place. This ensures that the controller is inhibited and all control
terminals have the defined state "LOW".
Device protection
Frequent mains switching (e.g. inching mode via mains contactor) can overload and
ƒ
destroy the input current limitation of the drive controller:
– For this reason at least 3 minutes have to pass between two starting operations.
– Use the "safe torque off" safety function (STO) if safety-related mains
disconnections occur frequently. The drive variants Vxx4 are equipped with this
function.
Protection of the machine/system
Drives can attain dangerous overspeeds (e. g. setting of high output frequencies in
ƒ
connection with motors and machines not qualified for this purpose):
– The drive controllers do not provide protection against such operating conditions.
For this purpose, apply additional components.
