In a standard PowerWave 3000T the UPS batteries are mounted
within the UPS module. If you require a longer battery autonomy time
than is possible using the standard internal batteries, you can:
• Use one of the larger UPS cabinets – for example, use a
Cabinet ‘B’ or ‘C’ cabinet which have more space for batteries
than the Cabinet A.
• Install the batteries in an external battery cabinet.
Note: It is not permissible to connect an external battery
cabinet in parallel with the UPS internal batteries. If an
external battery cabinet is used no batteries are fitted within
the UPS cabinet.
1.
Disconnect the wires for internal battery at the
bottom of FA3 (shown red in the illustration).
2.
Connect the wires between FA3 and the
External Battery TB at the bottom of the UPS
cabinet (shown in green).
3.
Connect the cables between from the external
battery cabinet and the UPS External
Battery TB.
Key Point:
The UPS is delivered with an optional
external batteries connection terminals only if it has
been ordered without batteries.
CAUTION: The following changes must be carried out by a
qualified electrician or other suitably approved personnel
before the UPS is powered up or commissioned.
