Connection of an extension unit
Up to 3 extension units (optional) can be connected to a single recorder. Use the dedicated cable (provided with the extension
unit) to connect between the extension unit and the recorder.
When connecting multiple extension units (WJ-HDE400) or when newly adding extension units, connect as follows. Refer also to
the operating instructions of the extension unit.
Important:
• Make sure to use the dedicated cable provided with the extension unit to connect.
• Fix the connection cable firmly using the cable clamp provided with the extension unit. When the cable is not connected firm

• Do not loop and bundle the cable in a circle.
• When installing the recorder or the extension unit in the rack, make a space of 1U (44 mm) above and below each of them
for ventilation.
