safety recommendations

■warning: every Comet UPS is equipped with its own internal power source, i.e. the backup battery. Consequently the load may energised even if the AC input power supply has been cut;

■the load is supplied with power as soon as the AC input power supply is connected, even if no LEDs are on;

■danger: dangerous voltage levels are present inside the Comet system. Any servicing requiring removal of the protection panels must be carried out by qualified personnel certified by MGE UPS SYSTEMS;

■Comet must be earthed;

■Comet must not be installed near liquids or in an excessively humid environment;

■Comet must be protected from penetration by liquids or extraneous objects;

■ventilation grates must remain free;

■Comet must not be placed in direct sunlight or near a heat source;

■Comet contains sealed lead-acid battery cells that must be disposed of in accordance with applicable environmental regulations;

■prior to installation, store Comet in a dry location. Storage temperatures must be between: –20°C and +45°C ;

■if Comet must remain unused for a long period, monthly re-energising for a

24-hour period is advised to recharge the battery. Otherwise, the battery may be damaged irreversibly;

■in accordance with standard EN 50091-1, Comet UPS users must affix warnings on all primary power isolating devices installed a certain distance from the UPS in order to alert maintenance personnel of the presence of a UPS on the circuit; the warning must display the following text or its equivalent:

"an uninterruptible power supply is present and must be isolated before carrying out any work on this circuit";

■warning: this is a product for restricted sales distribution to informed partners. Installation restrictions or additional measures may be needed to prevent disturbances.
