Chapter 1 Safety Information and Precaution
High-voltage AC drive units are high-voltage rated products with dangerous voltages of 6kV
or 10kV inside the cabinet. Therefore, the user must read and understand the ACH200 High Voltage
AC drive Operating Instructions carefully before installing and putting the equipment into operation,
and strictly comply with the operating procedures. Failure to operate in accordance with the
provisions of this manual may result in injury or death and property damage, for which the offender
is responsible.
1.1 Description of Safety Information

accidents or even death.
Warning: Failure to observe the relevant safety instructions may result in personal injury or
abnormal functioning or damage to the equipment.
Caution: Matters requiring attention or operating procedures in order for the equipment to function
properly.
Trained professional:
This product must be installed, wired, operated and maintained by trained personnel. The term
"trained professional" in this manual means that the person working on the equipment must be
trained in the installation, wiring, operation and maintenance of the equipment and must be able to
respond correctly to any emergencies that may arise during use.

Dangers
◆The AC drive unit and bypass cabinet of this product are in a high-voltage hazardous area,
do not open the cabinet door when high voltage is applied.
◆Operation of the AC drive unit or bypass cabinet must be in accordance with high voltage
operating procedures and the operator must wear insulated shoes and gloves; and the site
must be supervised by another operator.
◆When the input mains power is switched on, the terminals of the high voltage AC drive unit
remain energised even when the universal high voltage AC drive unit is switched off, so do
not touch them.
◆Maintenance checks on the Universal High Voltage AC drive Unit must be carried out only
after the high voltage power supply has been de-energised and it has been confirmed that
the power modules have been de-energised for 10 minutes.
◆Do not touch any part of the cabinet if you cannot verify the presence of voltage in the
cabinet.
◆Maintenance checks and component replacement must be carried out by trained
professionals.
◆A non-compliant ground resistance can be dangerous and needs to be checked regularly
(weekly is recommended) for a ground resistance of less than 4Ω.
◆When the system is shut down and maintenance is required for loads such as high-voltage
motors or fans and pumps, ensure that the circuit breakers in the front-level switchgear of
the high-voltage frequency-controlled device have obvious mechanical breakpoints and
that all isolation cutters in the bypass cabinet are in the disconnected position. When the
system is in continuous operation and maintenance is required for the standby motor or
load, safety measures should be taken on the standby motor side.
◆Verify that the input power supply meets the requirements of the product specifications.
◆Input and output cables to meet requirements for insulation, capacity, etc.
Warning
◆When moving, transporting and placing the equipment, it is important that the equipment is
placed horizontally and level.
◆When lifting the AC drive, it is strictly forbidden to use the top ring of the cabinet, and to
ensure that the lifting force of the equipment is sufficient and that the lifting and lowering
process is gentle.
◆Do not drop (leave) foreign objects such as wires, paper, metal shavings or tools in the cabinet.
◆Do not put into installation and operation if the components of the high voltage AC drive unit

Chapter 1 Safety Information and Precaution ACH200 Series High Voltage Variable Frequency Speed Control System Operating Manual

are damaged.
◆Install protective barriers (marked with a high voltage hazard symbol) at the necessary
locations and do not remove them while the equipment is in operation.
◆Do not disconnect the power to the cooling unit while it is in operation as this can lead to
overheating and damage to the system equipment.
◆Do not control the operation/stopping of the high voltage AC drive by switching the input
power on/off.
◆The order of power up and down should follow: when starting, turn on the control power first
and then turn on the high voltage power. When stopping, stop the stable motor first, then
disconnect the high voltage power supply, then disconnect the control power supply.
◆During operation, the user should monitor the load operation at all times and stop the machine
in case of irregularities.
◆It should be ensured that the ambient room temperature where the system is installed is within
the range of 0°C to 40°C.
◆After a period of operation, mechanical vibrations may cause loosening of the electrical contact
parts, resulting in poor contact and, in serious cases, damage to the components and the whole
machine. It is recommended that regular maintenance and cleaning checks be carried out as
required to avoid damage.
◆A system for recording the operating condition of the equipment and applying maintenance
systems should be developed.
◆Do not place flammable and explosive substances in or near the cabinet of the high voltage AC
drive unit.
◆The input and output cables should be wired according to the terminal markings, do not connect
them incorrectly as this may cause damage to the unit.
1.3 Safe Operation
This series of products is suitable for 3kV~11kV power supply system, the equipment is
directly connected to the high voltage grid, please take the following safety precautions when
operating:
1) The operator must wear high-voltage insulated shoes before entering the operating position of
high-voltage equipment.
2) Insulation mats shall be laid around the equipment.
3) High pressure operation by a single person is strictly forbidden.

1.3.1 Pre-power Check after Initial or Maintenance Overhaul
◆Make sure the high voltage input and output cable connection terminal screws are tight.
◆Make sure that the cables between the cabinets, which have been separated due to transport,
are properly and tightly connected.
◆Make sure that all control and signal cables are correctly and tightly connected.
◆Make sure that the system ground wire between all cabinets separated by transport is reliably
connected to the plant ground.
◆Make sure that the series cables between the units and the neutral cable are correctly and tightly
connected.
1.3.2 Pre-routine Power Supply Check
󰵛Remove all grounding protection wires before sending power.
󰵛Check that the filters do not need replacing.
󰵛Check that the AC drive fault message has been processed correctly.
󰵛Close and lock the cabinet door of the AC drive.
1.3.3 Power Outage Operation
1. Notify all relevant work stations to prepare for power failure.
2. Press the "stop" button of the high-voltage AC drive to stop the operation of the equipment.
3. Disconnect the circuit breaker of the user switchgear.
1.3.4 Inspection Operation
◆Take the necessary measures when repairing the line: disconnect the user's switchgear circuit
breaker, disconnect the disconnecting switch in question and at the same time hang a warning
sign to prevent others from delivering power midway.
◆Make sure that it is stopped and that the high-voltage live indicator does not display.
◆After the high and low voltage power failure, the power must be tested before work; for high
voltage testing, the corresponding voltage level of the detector should be used and insulating
protective equipment must be worn.
◆After verifying that there is no electricity, ground the three-phase incoming wires of the
construction equipment to ensure the safety of the staff.

Chapter 1 Safety Information and Precaution ACH200 Series High Voltage Variable Frequency Speed Control System Operating Manual

◆Grounding wires should be installed in all possible places of the construction equipment, and
for two-way power supply units, when servicing a busbar cutter
◆In the case of disconnect switches or load switches, the two busbar cutters should be
disconnected and the two ends of the construction cutter should be grounded.
◆When installing the grounding wire should first be grounded, after hanging the grounding wire,
remove the grounding wire in the opposite order, removal, connection should wear insulated
protective equipment.
◆The grounding wire should be hung in a place where it is readily visible to staff and a "man at
work" warning sign should be placed at the grounding wire.
