• The remote controller cord may be extended up to 500 m. Since the remote
controller cord supplied with the unit is 10 m-long, use those electric wires or
(two-core) cables of 0.3 mm
2
to 1.25 mm
2
for extension. Do not use multi-
conductor cables to prevent possible malfunction of the unit.
(1) Connect the remote controller cord to the terminal block for the lower
case.
Caution:
Do not use crimp-style terminals for connection to the remote controller ter-
minal block to eliminate contact with the boards and resultant trouble.
(2) Set the dip switch No.1 shown below when using two remote controller’s
for the same group.
Setting the dip switches
The dip switches are at the bottom of the remote controller. Remote controller
Main/Sub and other function settings are performed using these switches. Ordi-
narily, only change the Main/Sub setting of SW1. (The factory settings are all “ON”.)

(1) Put the upper latches (at two locations) first then fit the upper case into
the lower case as illustrated.
(2) To remove the upper case, put a slotted screwdriver tip in the latches as
shown in the diagram then move the screwdriver in the direction of ar-
row.
Caution:
• Do not move the screwdriver while inserting the tip far into the latches to
prevent broken latches.
