• Make sure to shut down the power supplies of all phases on the outside before starting
installation or wiring.
If the power supplies are not shut down, you may get electrical shock or the unit may be
damaged.
Caution
• Units should not be installed in areas subject to the following conditions: excessive or
conductive dust, corrosive or flammable gas, moisture or rain, excessive heat, regular
impact shocks or excessive vibration.
• Take special care not to allow debris to fall inside the unit during installation e.g. cut
wires, shavings etc. Once installation is complete remove the protective paper band: to
prevent overheating.
General notes
• Always ensure that mounted units and blocks are kept as far as possible from high-volt-
age cables, high-voltage equipment and power equipment.
• Wiring cautions
• Do not run input signals in the same multicore cable as output signals or allow them to
share the same wire.
• Do not lay I/O signal cables next to power cables or allow them to share the same trunk-
ing duct. Low voltage cables should be reliably separated or insulated with regard to high
voltage cabling.
• Where I/O signals lines are used over an extended distance consideration for voltage
drop and noise interference should be made.
