Connecting and disconnecting the internal battery
Air transportation regulations require that battery products are disconnected while in
transit. The RT-UPS is shipped with the internal battery disconnected. The battery will
need to be connected before the RT-UPS can be used. These instructions can be used to
connect and disconnect the battery.
There are two versions of the RT-UPS. Newer models can be identified by the large
battery isolation switch on the top panel. This switch connects and disconnects the
internal battery. In normal operation the switch should remain in the on position “I”,
however, when being transported by air, the switch should be set to the off position “0”
to isolate the battery.
Older versions of the RT-UPS require some disassembly in order to access the battery.
Although the RT-UPS does not need to be opened in a full electrostatic free
environment, you should take care to discharge yourself by touching the metal case
before touching any of the internal components.
To open the older model RT-UPS, undo the four front panel screws using a No.1
Philips screwdriver as shown in Figure 1. Occasionally the two screws on the rear panel
also need to be undone to remove the lid.
