2.8 Installation of the PowerServices TelPac external unit for Comet UPSs

For this installation it is necessary to de-energise the UPS. The various PowerServices TelPac components do not present an electrocution hazard for the installer.

It is necessary to initially check:

◗That the UPS is equipped with a JBUS/RS485 communication card 16 in one of its slots situated at the back or that such a card is available for installation (ref. 6761294 JOJO).

◗That a UPS-secured outlet is available near to the UPS (L < 1m) as well as a telephone outlet (L < 4m).
