Safety Instructions Precautions severity Follow this advice for good practice. Not following can lead to malfunctioning or possibility of injury to the user. High risk of malfunction or damage to the inverter or installation, possibility of injury to the user. Earth and grounding. Potential risk of electric shock or damage to inverter or installation. High inmediate risk of serious injury to the user, inverter or installation. Risk if manipulated by unqualified personnel WARNINGS AND CAUTIONS Instruction manual Read throuhfully this instruction manual before using the Variable Speed Drive, VSD Mains voltage selection The variable speed drive may be ordered for use with the mains voltage range listed below. SX-V-4: 230-480 V SX-V-6: 500-690 V IT Mains supply The variable speed drives can be modified for an IT mains supply, (non-earthed neutral), check manual and contract your supplier in case of doubt. EMC Regulations In order to comply with the EMC Directive, it is absolutely necessary to follow the installation instructions. All installation descriptions in this manual follow the EMC Directive. Transport To avoid damage, keep the variable speed drive in its original packaging during transport. This packaging is specially designed to absorb shocks during transport. Handling the inverter Installation, commissioning, dismounting, taking measurements, etc, of or on the variable speed drive may only be carried out by personnel technically qualified for the task. The installation must be carried out in accordance with local standards. Omron SX inverter manual 1
Condensation If the variable speed drive is moved from a cold (storage) room to a room where it will be installed, condensation can occur. This can result in sensitive components becoming damp. Do not connect the mains voltage until all visible dampness has evaporated. Grounding the inverter Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire. Power factor capacitors for improving cos Remove all capacitors from the motor and the motor outlet. Incorrect connection The variable speed drive is not protected against incorrect connection of the mains voltage, and in particular against connection of the mains voltage to the motor outlets U, V and W. The variable speed drive can be damaged in this way. Stop motion mechanical device to ensure safety The inverter controls the motor electrically, but has no means to stop it mechanically under some types of failures... In applications where mechanical stop is required to a degree of safety, a safety assurance study should be carried out to determine the need of additional mechanical braking devices. Braking resistor and regenerative braking units In case the application needs it, be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a burn due to the heat generated in the braking resistor/regenerative braking unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is detected in the braking resistor/regenerative braking unit. Electric protection of installation Take safety precautions such as setting up a molded-case circuit breaker (MCCB) or fuses that matches the Inverter capacity on the power supply side. Not doing so might result in damage to property due to the short circuit of the load. Wiring works and servicing the inverter Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious injury due to an electric shock. Do not dismantle, repair or modify this product if you’re not authorised and qualified for it. Doing so may result in an injury. DC-link residual voltage After switching off the mains supply, dangerous voltage can still be present in the VSD. When opening the VSD for installing and/or commissioning activities wait at least 10 minutes. In case of malfunction a qualified technician should check the DC-link or wait for one hour before dismantling the VSD for repair. Opening the variable speed drive cover Only qualified technician can open the inverter. Always take adequate precautions before opening the inverter. Although the connections for the control signals and the switches are isolated from the main voltage, do not touch the control board when the variable speed drive is switched on. Do not manipulate inverter under power Do not change wiring , put on or take off optional devices or replace cooling fans while the input power is being supplied. Doing so may result in a serious injury due to an electric shock. Inspection of the Inverter must be conducted after the power supply has been turned off. Not doing so may result in a serious injury due to an electric shock. The main power supply is not necessarily shut off even if the emergency shutoff function is activated. 2 Omron SX inverter manual
