3. Connecting PZ-01RC
4. Connecting Lossnay unit
Securely connect the transmission cable from the remote controller to the input terminal block (TM104). (No polarity)
Wire type: two-core sheathed cable
Wire diameter: 0.3 mm

Keep the overall length of the transmission cable between Dx-coil unit and the remote controller within 200 m.
Note:
• Do not tighten screws of terminal block with a torque larger than 0.5 Nm. It could damage the PCB.
• Do not connect the power supply cable.
• Remote controller cable should be rotated 3 times around the ferrite.
• Single wires such as PVC wires cannot be connected.
Connect the lead wire cable (accessory) to CN120 (GREEN) on PCB B of Dx-coil unit and CN20 (GREEN) on PCB of Lossnay unit.

Pass the power supply cable through the bush* and connect to the TB6 terminal
block using the round terminals. Connect the ground wire to the screw and secure
tightening the bush.
(* Use an item that can firmly secure the cable such as a PG connector.)

F Dx-coil unit
*1: If the installed earth leakage circuit breaker does not have a function to protect over-current, install a breaker with
that function along the same power line.
*2: A breaker with at least 3.0 mm contact separation in each pole shall be provided. Use earth leakage breaker (NV).
The breaker shall be provided to ensure disconnection of all active phase conductors of the supply.
2. Connecting the power supply cable
<CAUTION>
• Always separate the power supply cable and transmission cable by 5 cm or more to prevent malfunctioning of the unit.
• If the length of the stripped Power supply cable is too long, the conductors may touch and short out.
• Do not tighten screws of terminal block with a torque larger than 0.5 Nm. It could damage the PCB.
