Setting of End Terminal Resistance
Before shipment, No.1 pin of DSW10 is set at the “ON” side.
In the case that the outdoor units quantity in the same H-link is 2
or more, set No.1 pin of DSW10 at the “OFF” side from the 2nd
unit. If only one outdoor unit is used, no setting is required.

NOTE:
– Follow local codes and regulations when selecting
field wires.
– The above wire sizes marked with
É
are selected at
the maximum current of the unit according to the
European Standard, EN60 335-1. Use the wires which
are not lighter than the ordinary polychloroprene
sheathed flexible cord (code designation H05RN-F).
– The above wire sizes marked with
Ê
are selected at
the maximum current of the unit according to the wire,
MLFC (Flame Retardant Polyflex Wire) manufactured
by HITACHI Cable Ltd. Japan.
– In the case that the power cables are connected in
series, add each unit maximum current and select
wires below.
– The earth cable size complied with local code:
IEC 245, No. 571.
