Precaution during the wire connection:
●
The dashed line as shown in the fi gure must be conducted on spot by construction personnel.
●
Please use the switch, its contact point separate distance is above 3 mm.
●
Please use the switch, its rate current is above 10A..
●
Recommended to use the wire for connecting power supply cord and switch, its rate voltage is
300V/500V as stipulation of 60227 IEC 53 (soft wire).
At this time, please use the three-core wire containing green/yellow wire for power supply cord;
besides, use the two-core wire for connecting SW1, SW2 and switch inside the unit; use the
two-core wire for Air-con operation(please omit the connection if it’s not used the Air-con
operation);use the four-core wire for connecting other terminal parts and switch, the nominal
cross-section area for above-mentioned wire is 2.5 mm
2 .
When it’s used the remote control for
switch, the wire connected with switch, its cross-section area is 1.5 mm
2
.
●
Please use the torque below the 1.2 N to fi rmly connect the lead wire and terminal parts, no
loosen of connection. Please note the power supply cord in connection is not adhesive with solder.
●
Air volume can be adjusted to two modes of high/low and strong/low. Factory setting is mode of
high + low. Please adjust it as customer required if necessary.
●
When adjusting the air volume from high to strong, please separate the connector of the red line
and the blue line, and link the connector of red wire and white wire (shown as chain dotted line).
●
If several units operate together, the total current for all equipment must be less than the half rate
current of switch.
●
Ground connection is required.
●
After completing the wire connection, please fi x the cover of switch box by the screws.
●
When the power supply cord is damaged, in order to avoid the danger, please entrust the
authorized personnel to conduct the changing work, and get the contact with the sale shop and
