Mounting and installation
The PLC should be secured to an enclosed cabinet while mounting. For
heat dissipation, make sure to provide a minimum clearance of 50mm
between the unit and all sides of the cabinet. (See the figure.)
Rail Mounting: Use standard 35 mm rail.
Screw Mounting: Each MPU or extension module has two positioning
screw holes, the diameter of the hole is 4.5mm. Please refer to the
dimension figure for the location of the positioning holes and their
spacing.
To avoid over temperature and for a better heat dissipation, do not
mount PLC to a position near to the bottom/top of the cabinet. Do not
mount PLC in vertical direction.
Extension Module Wiring: Connections between extension modules and connections between module and MPU are
achieved through bus.An extension cable will be configured to every extension module, for the connection between two
different modules.
Connection methods: turn the right side of extended interface (the last MPU or extension module) over, plug the extension
cable in the extended interface, then press down the cover of the extended interface to reset the interface, the extended
interface at the right side of the module will be reserved for extension of the next module. Connect all extension modules in turn
in the same way.

11. Address Setting
Haiwell PLC with Ethernet port, the default IP address is : 192.168.1.111, subnet mask: 255.255.255.0,
gateway: 192.168.1.1. Hardware DIP dial switch address range: 1-15, the default address is 1. If you
need to set a bigger adress range, you can set on the software after connection with PLC, it can be set
on the PLC parameter option in the sofware menu by checking on the "soft address" with the range of
1-254(the soft address is prior to the hardware dial address).
12. Power Supply Wiring
There are two kinds of power supplies for PLC: AC input and DC input. Please pay particular attention to the following notes:
AC input voltage is 100~240VAC 50/60Hz unless otherwise stated. Connecting any one of the AC input wires to the
terminal-L and terminal-N on the MPU will be OK, but for safety's sake, please connect the two wires (Live Wire & Neutral
Wire) of AC input to terminal-L and terminal-N respectively.
Any AC110V or AC220V connected to the +24V terminal or input points will permanently damage the PLC.
Please use wires of 2.5mm or above for the grounding of the MPU.
