Chapter 7 Peripheral Equipments and Options
7.1 Safety Precautions
User must obey to the following safety rules and related requirements while using the peripheral equipments and
selecting components.
●
No operation under power connected state. Otherwise, there is danger of electric shock.
●
Before operation, please cut all related equipments power, ensure that the main circuit
DC current has droped to safe range. And please operate after 5 mins.
●
No operation while cover/panel is dismantled. Otherwise, there is danger of electric
shock.
●
Do not dismantle the cover or PCB under power connected state. Otherwise, there is
danger of electric shock.
●
Only professional person can install, debug or maintain the peripheral equipments and
options. Otherwise, there is danger.
●
Do not ware loose clothes when install, debug, maintain. Rated protective tools and
safeguard should be adopted.
●
Do not change wire, dismantle jumping wire, optional card, or change cooling fan while
the inverter is running. Otherwise, there is danger of electric shock.
●
Tighten screw according to named torque. If main circuit wire connection is loose, there is
danger of overheat fire.
●
Earth of the peripheral equipments and options must be reliable to prevent human body
injury.
●
While operation, please follow the ESD regulations. Otherwise, the inverter maybe
damaged.
●
Do not cut the power supply while the inverter is outputting voltage. Otherwise, the
inverter maybedamaged.
7.2 Peripheral equipments
Normal peripheral equipments are showed as follows. To order the peripheral equipments, please consult our dealer or
sales department.
Peripheral equipment
Functions
Breaker
Protect power system and prevent malfunction impact other
equipments working when short-circuit happens. And
over-load protection.
Leakage current breaker
Earth protection prevent electric shock(suggest to use the
type which can prevent high-frequency leakage current)
Electromagnetic contactor
Separate power and inverter indeed and realize basic relay
control.
AC input reactor
Improve power side factor and isolate the noise disturbance
to the frequency inverter from the power side.
