Installing a single CU
After the CU is connected the unit can be operated straight away without any configuring.
Installation with 2 CUs
If an installation is carried out providing 2 new CUs, it is important when powering these up
for the first time, that this is done sequentially, to allow the CUs to acquire their individual
identity on the SPARC II bus:
2 newly installed CUs:
• Power on VHF
• Power on first CU
• Power on second CU
If an additional CU is installed in a system already working with a single CU, the
already existing CU must be switched on prior to the first power-on of the new CU.
Adding a CU in an installation already providing one CU:
• Power on VHF
• Power on the existing CU
• Power on the newly installed CU
This procedure is also followed if a CU is moved from another installation to this installation.
Always turn on the existing CU before turning on the last acquired one - when powering for
the first time after installation.
