Removing a module from an installed system
The ability to permanently reduce the number of modules in the UPS is an option available by
special order.
(The LCD screen images in this section are from a 240 kW system, and show eight modules.
The screen for a 120 kW system shows four modules.)
To remove a module in an operational system:
1.
Refer to section 6.1 “Safety considerations”.
2.
The
Centric
controller must be informed of the change in the output capacity of your system. On the
LCD control panel, from the main menu navigate to
"Setup > System > System type". Determine the new capacity of the system by multiplying the
remaining number of modules by 30 kW.
For example, if you remove one module from a 240 kW system (8 modules) you have 7 modules left
and should choose 210 kW as the new system type (see Figure 55 and Figure 56).
A password is required to perform this function. If you do not have the required password, contact
your distributor or sales agent.
There is an exception to this step, and it depends upon the type of license you have. For example, If
you have removed a 30 kW module from a 240 kW system giving you a 210 kW system, and your
license type is defined as “up to 240 kW”, then you can skip to the next step. Another example: if you
remove a 30 kW module from a 90 kW system giving you a 60 kW system, and your license type is
“up to 120 kW”, skip to the next step.
