2.5 Electrical Connection
Electric shock
Dangerous voltages can be present at the mains input and all power connection terminals (e.g. motor
connection terminals, link circuit) even when the device is not in operation.
•
Before starting work, check that all relevant components (voltage source, connection cables,
connection terminals are free of voltage using suitable measuring equipment.
• Use insulated tools (e.g. screwdrivers).
• DEVICES MUST BE EARTHED.
Temperature sensor and PTC (TF)
As wi
th other signal cables, thermistor cables must be laid separately from the motor cables
Otherwise the interfering signals from the motor winding that are induced into the line affect the
device.
Ensure that the device and the motor are specified for the correct supply voltage.
