Installation and Maintenance
Installation and Maintenance
9. Electrical Installation
●
Use an ELB (Electric Leakage Breaker). If not used, it may cause an electric shock or a fire.
●
Do not operate the system until all the check points have been cleared.
(
A
)
Check to ensure that the insulation resistance is more than
2MΩ,
by measuring the
resistance between ground and the terminal of the electrical parts. If not, do not operate the
system until the electrical leakage is found and repaired.
(
B
)
Check to ensure that the stop valves of the outdoor unit are fully opened and then start the
system
.
NOTES
:
1
)
Follow
local
codes
and regulations when selecting field wires , and all the above are the minimum size.
2
)
The wire sizes marked in the table are selected at the maximus current of the unit according to the
European Standard, EN60335
-
1. Use the wires which are not lighter than the ordinary polychloroprene
Place the round crimp-style terminals on the wires up to the
covered part and secure in place.
When
connecting
the terminal block using a single core
wire, be sure to perform curing.
3
)
When transmitting cable length is more than 15 meters, a larger wire size should be selected.
4
)
Use a shielded cable for the transmitting circuit and connect it to ground.
Flexible cord
sheathed flexible cord (code designation H07RN-F).
When
connecting
the terminal block using flexible cord, make sure to use the round crimp-style terminal
for connection to the power supply terminal block.

In the case that power cables are connected in series
,
add each unit maximum current and select
wires below
