Important:
 Ensure that the temperature inside the rack does not exceed 45 ºC {113 ºF}.
 During installation, we recommend installing a fan to keep the temperature in the rack  below 30 ºC { 86 ºF}.
 When installing the extension unit in the rack, leave a space of
1 unit (44 mm {1.73}) a bove and below each unit. 
 Leave space  between racks and ensure proper ventilation
around the racks.

Up to 5 extension units can  be connected to one network disk recorder (WJ-ND400).
Connect the extension unit and the net work disk recorder with the connection cable (1 m {39.4 }) provided. 
Follo w the points  below when connecting the system in a ne w installation. Also, refer to the net work disk recorder s Installation Guide. 
Connections 
Important:
 Connecting extension units re quires the included connection ca ble. 
 Be sure to use the ca ble clamp provided with the extension unit to secure the connection ca ble. If the connection is poor or the connector is
not secure, the system may  become unstable and unable to record images. 
 Do not  wind the ca ble in a coil.

When connecting multiple extension units to a network disk recorder ( WJ-ND400), place the recorder in the center of the rack. 
Connect the extension unit and the net work disk recorder with the connection cable (1 m {39.4 }) included  with the extension unit. 
Note:
We recommend installing the net work disk recorder in the middle of the rack  because if you install it at the top or bottom of the rack, the
ca ble may not  be long enough. 
 When installing the extension unit in the rack,  leave a space of 1 unit (44 mm {1.73 }) above and below each extension unit. 
 Be sure to secure the connection cables  with the cable clamp. 
If the connection is poor or the connector is not secure, the system may  become unstable and unable to record images. 
 Keep the ca bles as short as possi ble. Looped cables or large distances  between pieces of equipment may cause malfunctions. Do not  wind
the ca ble in a coil.
