5. Electrical work

sConsult all related regulations and power companies beforehand.

Warning:

Electrical work should be handled by qualified electric engineers in accord-

ance with all related regulations and attached instruction manuals. Special

circuits should also be used. If there is a lack of power capacity or a defi-

ciency in electrical work, it may cause a risk of electric shock or fire.

sConnect all wires without looseness.

•Fix power source wiring to control box by using buffer bushing for tensile force

(PG connection or the like).

sNever connect the power cable to the terminal board for control cables.

(Otherwise it may be broken.)

sBe sure to wire between the control wire terminal boards for indoor unit,

outdoor unit and BC controller.

Transmission cables are of crossover wiring method by non-polarized 2-wires.

Use 2-core shielding cables (CVVS, CPEVS) of more than 1.25mm2 in diameter

for transmission cables.

6. Setting addresses and operating units

The address switch of each BC controller is set to “000” when shipped from the

factory. Check it.

•Set the address switch to 1 + the address of the outdoor unit.

sThe BC controller address should generally be set to 1 + the address of

the outdoor unit. However, if this would result in it having the same ad-

dress as another outdoor unit, set the address between 51 and 100, mak-

ing sure that it is different from the address of other controllers.

•Please refer to the outdoor unit installation manual.

7. Test run

Before getting test run checked

sAfter installing, piping and wiring the indoor units and BC controllers,

check to see again that there is no refrigerant leakage or no slack on

power and control cables.

sUse a 500 V megger to check that there is an insulation resistance of

more than 1.0 MΩ between the power terminal bed and the ground. If it is

less than 1.0 MΩ, do not get operated.
