CAUTION
Wear adequate personal protective equipment (protective gloves, safety glasses,…)
when installing, maintaining or servicing the system.
WARNING
Tear apart and throw away plastic packaging bags so that nobody, especially
children, can play with them. Possible risk: suffocation.
2.1.2 Installation site
Do NOT install the equipment in a potentially explosive atmosphere.
2.1.3 Electrical
DANGER: RISK OF ELECTROCUTION
▪Turn OFF all power supply before connecting electrical wiring or touching
electrical parts.
▪Disconnect the power supply for more than 10minutes, and measure the voltage
at the terminals of main circuit capacitors or electrical components before
servicing. The voltage MUST be less than 50VDC before you can touch electrical
components. For the location of the terminals, see the wiring diagram.
▪Do NOT touch electrical components with wet hands.
▪Do NOT leave the unit unattended when the service cover is removed.
WARNING
A main switch or other means for disconnection, having a contact separation in all
poles providing full disconnection under overvoltage categoryIII condition, shall be
installed in the fixed wiring.
WARNING
▪ONLY use copper wires.
▪Make sure the field wiring complies with the applicable legislation.
▪All field wiring must be performed in accordance with the wiring diagram
supplied with the product.
▪Make sure to install earth wiring. Do NOT earth the unit to a utility pipe, surge
absorber, or telephone earth. Incomplete earth may cause electrical shock.
▪Make sure to use a dedicated power circuit. NEVER use a power supply shared by
another appliance.
▪Make sure to install the required fuses or circuit breakers.
▪Make sure to install an earth leakage protector. Failure to do so may cause
electric shock or fire.
WARNING
▪After finishing the electrical work, confirm that each electrical component and
terminal inside the electrical components box is connected securely.
▪Make sure all covers are closed before starting up the unit.

2.2 Daikin system equipment
The installation requires:
-The gateway MCS341-DS1-111, spare part number EU.SB.5000072. The wiring
to connect to the power convertor is included here.
-An AC/DC power convertor (PWD-90AW24), spare part number 999175A.
And one of the following:
-iTM controller, product number DCM601A51
-LC8 controller, product number DLC602B51
For more information on this equipment, see "4 To commission the iTM or LC8
controller"[421].
If there is a missing or defective part, contact the dealer where you purchased this
product.
2.3 System description
The Security gateway allows the iTM and LC8 to connect through the Security
gateway to the Daikin Cloud Service.
Now, instead of sending the report to the router directly, the iTM or LC8 controller
sends the report to the Security gateway first. The Security gateway transforms the
report format from http to https and then sends the transformed https report to
the Daikin Cloud Service via the router.
