Safety instructions 17
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 option +E202 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.
Overvoltage can cause the motor to rush to its maximum speed.
• We do not recommend that you secure the cabinet by arc welding. If you have to, obey
the instructions in section Arc welding on page 50.
• 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 terminals (UDC+, UDC-) 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.
WARNING! Obey these instructions. If you ignore them, equipment malfunction
and damage to the fiber optic cables can occur.
• Handle the fiber optic cables with care.
• When you unplug the cables, always hold the connector, not the cable itself.
• Do not touch the ends of the fibers with bare hands as the ends are extremely
sensitive to dirt.
• Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is
35 mm (1.4 in).
