9. Network wiring Copeland XWEB serial address • Connect to the ModBUS network using cable with shielded wires, minimum section 0.75mm2 (e.g. BELDEN8761). • Do not connect shield to ground. • Do not connect the "Gnd" terminal. • Remember to draw a map of the line. This will help you to fnd an error if something is wrong.

(JMP2 on the back side of the unit). Do not add the jumper if XWEB is placed in the middle of the RS485 line. Large ZX CDU connected to XWEB Large ZX CDU connected to the Copeland XWEB with the intelligent store solution module using RS485 Modbus. Connect the ZX CDU to the ModBUS network as shown on fgure 11.

11. Installation, system processing and commissioning Utmost care must be taken while handling the large ZX condensing unit. Please go through the contents below to ensure proper handling. a. Location and fxing Large ZX should always be installed in a location that ensures clean air fow. The minimum operating space for unit is described in below fgure.
b. Refrigeration piping installation All interconnecting pipes should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation. Even during installation, if the system is left for any reasonable period (say two hours), pipes should be re- capped to prevent moisture and contaminants from entering the system. Do not assume that the service connection sizes on the unit (at the service valves) are the correct size to run your interconnecting refrigeration pipes.
Page 31
e. Brazing recommendation Maintain a fow of oxygen-free nitrogen through the system at a very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system. If copper oxidization is allowed to form, the copper oxide material can later be swept through the system and block screens such as those protecting capillary tubes, thermal expansion valves, and accumulator oil return holes.
g. Start-up & operation Initial pressure test (by vacuum and nitrogen) Step-by-step • Use a 4-port gauge manifold with 3/8” hose and connections to the vacuum pump. The vacuum gauge does not have to be connected for this part of the process. •...

Additional oil charing in the system Copeland large ZX units are supplied with oil charge in the compressor as well as the oil separator / reservoir. However, depends on the length of interconnecting piping and the refrigerant charge in the system, there might be additional oil requirement.
i. Checks before starting and during running the system • Check all the valved are fully opened. • Check the oil level of compressor and the reservoir after running the unit for some time. • Check the discharge line temperature which is to be below 125°C. •...
