Chapter 1 Safety and Attentions
Definition of Safety:
In this manual, safety precautions will he presented as following two categories:
10 danger I Dangers caused hy operations beyond requirements may lead to serious
injury,and even death.
l&.attentionl Dangers caused by operations beyond requirements may lead to moderate
damages or minor injuries, as well equipment damages.
1.1 Safety Matters
I. Before installing:
10 danger I
Please do not use damaged and shot-part drives. There are risks of being hurt.
II. In installation:
10 danger I
Please install it on metal and other inflaming retarding objects: to keep away
from combustible, or it may give rise to fire alarm!
IA attention I
* More than two AC drives shall be placed in a same cabinet. Please pay
attention to the installation site (refer to Installation in Chapter 3) and
guarantee heat dissipation effects.
* Wires or bolts shall not fell into AC drive, or it will lead to the damages of
AC drive!
fil. In wiring
10 danger I
* It shall be constructed by professional electric engineering personnel, or
it will give rise to electric shock hazard!
* AC drive and power supply shall be separated by breaker, or it will cause
fire alarm!
* Before wiring, please confirm power off, or it will cause electric shock
hazard!
* Please make ground connection as standard requests, or it will cause electric
shock hazard!

IA attention I
* The input power line cannot be connected to output end, U, V, W, or it will
damage AC drive!
* Please confirm the equipped wires will accord with EMC requirements and
regional safety standards. For the adopted wire diameter, please refer to the
suggestions in manual, or it will lead to accidents!
* Brake resistor cannot be connected directly to the two ends of DC bus ( +)
and terminal(-), or it will cause fire alarm!
IV. Before power on
IA attention I
* Please confirm whether supply voltage class is in accord with the nominal
voltage of AC drive: whether connection location of input and output is
correct, and pay attention to check whether short circuit phenomenon exists
in peripheral circuit and whether the connected circuit is tight, or they will
cause damages to AC drive!
* Power on is permissible only AC drive is covered with plate, or it will give
rise to an electric shock!
IA attention I
* Pressure-tight test is not necessary for AC drive, and the product has been
maked relevant test before leaving factory, or it will give rise to accidents!
* Confirm whether all peripheral equipments have been connected correctly
as the circuits provided in this manual, or it may give rise to accidents!
V. After power on
10 danger I
* Please do not open the cover plate after power on, or it will give rise to
electric shock hazard!
* Do not touch AC drive and peripheral circuit with wet hands, or it will give
rise to electric shock hazard!
* Do not touch AC drive terminal, or it will give rise to electric shock hazard I
* After power on, AC drive will make security detection over external strong
electricity circuit. For the time being, please do not touch U, V and W
connection terminal or motor connection terminal of the AC drive, or it
will give rise to electric shock hazard!
