16 Safety instructions

Additional instructions and notes
WARNING! Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•
If you are not a qualified electrician, do not do installation or maintenance work.
•
Do not install a drive with EMC filter E200 on an ungrounded power system or
a high resistance-grounded (over 30 ohms) power system.
•
Do not connect the drive to a voltage higher than what is on the type designation label.
If you do, the brake chopper starts to operate which causes the overheating of the
brake resistor (if present). Overvoltage can also cause the motor to rush to its
maximum speed.
•
We do not recommend that you secure the cabinet by arc welding.
•
Do not do insulation or voltage withstand tests on the drive or drive modules.
Note:
•
The motor cable terminals of the drive are at a dangerous voltage when the input
power is on, regardless of whether the motor is running or not.
•
The DC bus and brake resistor terminals (UDC+, UDC-, R+ and R-) are at a
dangerous voltage.
•
External wiring can supply dangerous voltages to the terminals of relay outputs
(XRO1, XRO2 and XRO3).
•
The Safe torque off function does not remove the voltage from the main and auxiliary
circuits. The function is not effective against deliberate sabotage or misuse.
WARNING! Use a grounding wrist band when you handle the printed circuit
boards. Do not touch the boards unnecessarily. The boards contain components
sensitive to electrostatic discharge.
