General notes￭ Static electricityWARNING!Use a grounding wrist band when you handle printed circuit boards. Do not touchthe boards unnecessarily. The boards contain components sensitive to electrostaticdischarge.￭ Optical componentsWARNING!Obey these instructions. If you ignore them, damage to the equipment can occur.• Handle the fiber optic cables with care.• When you unplug the fibre optic 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 sensitiveto dirt.• Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is35 mm (1.4”).Checking the insulation of brake resistor and resistor cableWARNING!Obey the safety instructions of the drive. If you ignore them, injury or death, ordamage to the equipment can occur.If you are not a qualified electrician, do not do installation or maintenance work.1. Stop the drive and do the steps in section Electrical safety precautions (page 38) beforeyou start the work.2. Check that the resistor cable is connected to the resistor and disconnected from thedrive output terminals.3. At the drive end, connect the R+ and R- conductors of the resistor cable together.Measure the insulation resistance between the conductors and the PE conductor witha measuring voltage of 1000 V DC. The insulation resistance must be higher than1 Mohm.R-R+ohmPE1 kV DC,> 1 MohmElectrical installation 3911
