7.3 SETTING OF DIP SWITCHES AND RSW SWITCHES

7.3.1 Outdoor unit RAS-(2-3)WHVRP1, RAS-(4-10)WH(V)NPE and RASM-(2-6)(V)(N/R)E

7.3.1.1 Location of DIP switches and rotary switches
The PCB in the outdoor unit is operating with DIP switches and push switches. The location is as follows:
RAS-(2/2.5/3)WHVRP1 and RASM-(2/3)VRE

N O T E
DIP-IPM or PCB2 (depending on model) has a DSW1. When pin number 1 is set to ON position, the electrical current detections is cancelled. Pin
number 1 should be to OFF position after electrical work.

D A N G E R
Before setting dips switches, first turn the power source off and then set the position of the dips switches. In case of setting the switches
without turning the power source off, the contents of the setting are invalid.

DSW1 (Only RAS-(2/2.5/3)WHVRP1 and RASM-(2/3)VRE): No setting is required
When set pin number 1 to ON, the electric current detection is cancelled. Pin number 1 should be set back to OFF
after electrical work

DSW1 (RAS-(4-10)WH(V)NPE and RASM-(4-6)(V)NE): For Test run
