Installation steps
Carefully read this manual prior to installation and follow the instructions of the warnings on the labels of the equipment and in this manual at all times:
Warning: Switch off all power supply equipment before you start to install SAM4 in the control cabinet.
Notice: Wait at least ten minutes after switching off all the power supply equipment before starting activities. Internal capacitors of the Variable Frequency Drives (VFD) may need a discharge period after having been switched off. The risk of suffering serious electric shocks continues to be present within this period.
Warning: Use an approved and certified multimeter to confirm that the control cabinet is voltage-free.
Notice: Do not connect the device to a voltage that is greater than specified on the product label of the power supply adapter.
Notice: Do not install the device in atmospheres that fall outside the atmosphere specifications of humidity and temperature.
Warning: Always ensure that the equipment is not in the vicinity of moisture. Do not pour any liquid over or in an opening of the equipment. This will cause a fire or electrical shocks.
Warning: Never open the equipment.
Notice: The openings in the housing of all equipment are for air cooling. Do not cover the openings since this may lead to overheating.
Warning: All equipment uses low voltage up to 690 Volt alternating current (AC) which can cause serious electrical shocks and/or fire and may lead to serious injuries and even death. Taking extreme care is always recommended.
Notice: The equipment may only be installed by qualified engineers who are familiar with the safety, electrical engineering and EMC guideline requirements and this manual.
After completing all the steps of this chapter (install hardware) and the subsequent chapter (connect to motor), your SAM4 setup will be consistent with the below wiring diagram.
For medium-voltage assets, the SAM4 measurements take place in a low-voltage compartment. This is realized by using voltage and current transformers that transform the current and voltage to lower values. Therefore the sensors are not directly placed on the phase wires of the motor, but on the secondary side of the transformers.
