Model WY5122

General

Infilex ZM (Infilex: named for “Infinity” and “Flexible”) Model WY5122, integrated into savic-net FX BMS (building management system), manages remote units (also called sub-controllers), such as Infilex VC, Infilex FC, and Infilex SC.
Up to 50 remote units can be connected. Infilex ZM can control these units separately as well as per group.
Infilex ZM communicates with the savic-net FX center unit through the transmission trunk line NC-bus and with the remote units through the transmission trunk line SC-bus.

Connections of Data Setter (H-MMI)

1. Connection of Data Setter Model QY5111A
   No conversion cable is required. Directly insert the male connector of the Data Setter into the female connector provided on the Infilex ZM main unit.
   At this time, hold the male connector with the ◄ mark facing left and insert it as the mark points to the ► mark on the Infilex ZM main unit.

2. Connection of Data Setter Model QY7211A
   Convert the D-SUB connector to the mini DIN connector with the conversion cable (Part No. 83104995-001).
   At this time, hold the male connector with the ◄ mark facing left and insert it as the mark points to the ► mark on the Infilex ZM main unit.

Mounting Dimensions

DIN rail mounting
Mount and fix Infilex ZM on DIN rail so that it does not fall from the DIN rail.
Fasten the bilateral sides of Infilex ZM with two DIN rail mounting brackets (Part No. 83104567-001, separate order is required).

Direct screw-mounting

When Infilex ZM is mounted with screws, the screw tab (Part No. 83165861-001) is required.
Mount and fix Infilex ZM on the wall with two M4  8 screws.

Lengthwise mounting

Wiring

Wiring from power supply to terminal block
Attach the crimp terminals for the M3 screw terminal block to the wire ends, and connect them to the terminal block.

Wiring to the NC-bus Terminal Block
Since quick-fit screwless terminal block is used for the NC-bus terminal block, the procedure for wiring is specified as follows.

1. Strip the wire sheath 8 mm. (The gauge for the strip length is located at the front lower part of Infilex ZM main unit. If the stripped part is longer than 8 mm, the conductor will be exposed, causing electrical shock or short circuit between adjacent terminals. If it is shorter, the conductor may not contact the connector.)

2. Make sure that no wire fiber is protruded from the stripped conductor.

3. Press the button on the terminal block deeply enough to insert the wire using a slotted screwdriver.
   (Maximum button-pressing force is 14 N {1.4 kgf}.)

4. Release the button, and gently pull out the wire to make sure that it is tightly fastened. (If you pull out the wire diagonally, it may be disconnected.)
   Make sure that no wire fiber is protruded from the stripped conductor.

Precautions for connected cables
Neatly place the cables connected to Infilex ZM so as not to hide the parts shown in Fig. 8.
Make sure there is no slack in the wires from the cable ducts to Infilex ZM.

System indication label for the controller number
The indication tag has the system indication label on its back.
Turn it over and fill in the controller number on the label.

Protective sheet
After wiring installation, be sure to peel off the protective sheet before turning on the power.

1. Adhesive is applied to the sheet approximately 20 mm from the front edge. Peel off this area.
2. Tear off the sheet along the perforations.

Tube marker

Since Infilex ZM adopts quick-fit screwless terminal block for communication, communication cables are connected to the terminals without crimp terminal lugs. Therefore, if normal tube markers are used, they may come off when the cables are disconnected. To prevent this, use the Flat Tube Marker. It is held on a cable by friction and thus does not come off easily.

Maintenance (Lithium Battery Replacement)

Replace the lithium battery for backup (Part No. 83104934-001) every 5 years.

IMPORTANT:

• Only authorized service personnel is allowed to replace the battery.
• Do not touch the power supply unit when replacing the battery.
• Since the remaining battery capacity cannot be checked by measuring the terminal voltage, be sure to replace the battery every 5 years.
• Replace the lithium battery with the power ON.
• Replace the lithium battery every 5 years if the product is always in use (in ON state).
• If the product has never or hardly been operated (in OFF state) for a year, replace the lithium battery before the product operation.

Battery replacement

1. Pull out the battery holder using a slotted screwdriver.
2. Disconnect the connector and detach the lithium battery from the battery holder.
3. Place a new lithium battery in the battery holder and connect the connector to it.
4. Insert the battery holder into the main unit.
5. Fill in the date for next replacement (5 years after the replacement) on the tag using an oil-based pen.

Precautions for Use

• Do not mount the product under the conditions of high temperature and humidity.
• Do not drop the product.
• For the wire replacement, be sure to shut down the power. (Disconnect the wiring between the power supply and the product power terminals.)
• Before turning on the power, make sure that the wires are correctly connected.
• Several tens of seconds are required for the product normal operation after the power is turned on. During this time, the red LED “ERR1” (major failure) on the front lights up indicating major failure temporarily, but this does not indicate an error.
• Do not connect wires to vacant terminals.
• Leave at least 35 mm clearance between the top/bottom surfaces of the product and other devices.
• Peel off the protective sheet on the top surface of the product before turning ON the power.
