General

◗local operation. The "Monitor" alphanumeric display (see figure 34) may be installed behind the hinged cover of the hidden panel (see figure 25) on the control panel in all types of cubicles (UPS or Static Switch Cubicle).

◗remote operation. Installed in a special enclosure, the "Tele Monitor" provides the user with remote indications on system status. Two "Tele Monitor" units may be connected to the same system, one as a master for indications and remote control, the other as a slave for indications only.

The "Monitor" can operate in two different modes:

◗mono-cubicle: the option monitors only the cubicle in which it is installed;

◗multi-cubicle: "Monitor" can monitor all system cubicles (up to eight maximum). In this mode, the system is equipped with only one "Monitor" which may be installed in any of the cubicles.
