Check points after installation
1
Before supplying the power, measure the insulation
resistance values between the ground terminals and
individual power terminals (R/S/T/N) on the product,
by using the DC 500V insulation resistance tester.
- Measurement should be over 30MΩ.
2
Before supplying the power, use voltmeter and phase
tester to check the volgage and the phase.
- R, S, T terminal : Check the 460 V
(AG

CAUTION
ŷ
Do not measure the communication terminal. Doing
so, the communication circuit may be damaged.
ŷ
Check the short-circuit of the communication
terminal with a general circuit tester.
3
When N phase is connected to R, S, or T by wrong
wiring, over-voltage protection control will be in
effect and it will cut-off the power of the PCB. Check
the power cable connection of the N phase if the PCB
is not turning on.
4
Check the following after the installation is
completed.
Installation
work
ŷ
Have you checked the external
surface and the inside of the
product?
ŷ
Is there any possibility of short
circuit due to the heat generation
of the product?
ŷ
Is the place well-ventilated and
ensures service clearance?
ŷ
Is the product fixed securely to
withstand the external force?
Water pipe
work
ŷ
Have you completed the drain test?
ŷ
Is the drain pipe properly insulated?
ŷ
Is the strainer (50 Mesh) properly
installed at inlet of plate type heat
exchanger?
Electrical
wiring work
ŷ
Are the power cable and
communication cable tightened
firmly on the terminal block within
the rated torque recommendations?
ŷ
Have you checked for cross
connection of the power and
communication cables?
ŷ
Have you performed the grounding
work 3 to the product?
ŷ
Did you make sure to use 2-core
cable (not multi-core cable) for the
communication cable?
ŷ
Is the length of the wire within
allowed range?
ŷ
Is the wiring route correct?
Option
ŷ
When there's a possibility of
vibration generated from the
product, check if the vibration-
isolation frame is correctly installed.
