1.8 Maintenance
1.8.1 Routine Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause
the aging of the devices in the AC drive, which may cause potential faults or
reduce the service life of the AC drive. Therefore, it is necessary to carry out
routine and periodic maintenance.
(1) Routine maintenance involves checking:
• Whether the motor sounds abnormally during running
• Whether the motor vibrates excessively during running
• Whether the installation environment of the AC drive changes.
• Whether the AC drive's cooling fan works normally
• Whether the AC drive overheats
(2) Routine cleaning involves:
• Keep the AC drive clean all the time.
• Remove the dust, especially metal powder on the surface of the AC drive, to
prevent
the dust from entering the AC drive.
• Clear the oil stain on the cooling fan of the AC drive.
1.8.2 Periodic Inspection
Perform periodic inspection in places where inspection is difficult.
Periodic inspection involves:
• Check and clean the air duct periodically.
‐19‐
VM1000 Series
• Check whether the screws become loose.
• Check whether the AC drive is corroded.
• Check whether the wiring terminals show signs of arcing;
1.8.3 The Replacement of Vulnerable Components
The vulnerable components of the AC drive are cooling fan and filter electrolytic
capacitor. Their service life is related to the operating environment and
maintenance status. Generally, the service life is shown as follows:
Components name Lifetime
Fan 2 ～ 3 Year
Electrolytic capacitor 4 ～ 5 Year
Table 1-5 Lifetime of Wearing Parts
User can decide the replacing time according to its operation
(1) Cooling Fan
Damage causes: bearing wear, leaf aging
Judge standard: whether there is crack on the fan blase; whether there is abnormal
vibrating when turn on
(2) Filter Electrolytic Capacitor
Damage causes: the quality of input power is bad; the ambient temperature is relatively high;
frequent load jump, electrolyte aging
Judge standard: Whether there is liquid leakage or protrusion of safety valve or not,
electrostatic capacitance and insulation resistance measurement.
‐20‐
1.8.4 Storage of the AC Drive
For storage of the AC drive, pay attention to the following two aspects:
(1) Pack the AC drive with the original packing box provided by SAJ
(2) Long-term storage degrades the electrolytic capacitor. Thus, the AC drive
must be energized once every 2 years, each time lasting at least 5 hours. The input
voltage must be increased slowly to the rated value with the regulator.

Installation
places and
Precaution
AC drive need to be installed on the surface of incombustible object such as
support, panel and solid architectural facade, and fix the AC drive with
screws and bolts.
Since a great amount of heat will be generated when VFD is running there
needs to have sufficient space around for heat dissipation. If necessary, it also
needs to equip with mandatory ventilation and heat dissipation devices.
Because the channel for ventilation and heat dissipation is designed
vertically, the VFD needs to be installed horizontally other than horizontally
or transversely.

380VAC，50/60Hz
Voltage：Three phase 380VAC, permitted fluctuation range ±15%，
Frequency：50/60Hz, permitted fluctuation range ±5%
The protective earthing,signal ground should be separately wired
With the VFD installed, power distribution line, it can not use circuit
breaker with leakage protection etc.As for the VFD application, please
complete equipment grounding measures to ensure the security.
VFD power supply need to connect with the circuit breaker with short
circuit protection or rapid fuse protector
Under normal situation, VFD conduct start /stop control by its panel, control
terminals and other methods.
Usually, it is not suggested to adopt contactor as the switch device at VFD
power-supply side, nor use it as motor’s start/stop control device at VFD output
side. If it is done and contactor is disconnected when operating, it will easily
damage VFD.
Notes: Some industries or equipment (such as elevator) is required to use
contactor as security isolation device at VFD power-supply side and output
side, which is in conformity with the above requirements.
