Site Preparation | 15If the E300 is connected to a 220 VAC power supply, two power supply modules are required; four powersupply modules are required for full facility redundancy (2 + 2).For installation instructions, see Installing AC Power Modules on page 19 .2500W AC Power RequirementsDC PowerEach E300 system requires at least one load-sharing DC PEM to operate. Two DC PEMs are required forfull facility redundancy.For installation instructions, see Installing DC Power Entry Modules on page 22.DC PEM Power RequirementsCAUTION:• This equipment must be connected directly to the DC supply system earthing electrode conductoror to a bonding jumper from an earthing terminal bar or bus to which the D.C. supply systemearthing electrode is connected.• The DC supply source is to be located within the same premises as this equipment.• There shall be no switching or disconnecting devices in the earthed circuit conductor between theDC source and the point of connection of the earthing electrode conductor.ATTENTION:• Ce matériel doit être reccordé directement au conducteur de la prise de terre du circuitd'alimentation c.c. ou à une tresse de mise à la masse reliée à une barre omnibus de terre laquelleest raccordée à l'électrode de terre du circuit d'alimentation c.c.• La source d'alimentation du circuit c.c. doit être située dans la même pièce que le matérial.• Il ne doit y avoir aucun dispositif de commutation ou de sectionnement entre le point deraccordement au conducteur de la source d'alimentation c.c. st le point de raccordement à la prisede terre.Parameters SpecificationsNominal Input Voltage 100 - 120 VAC Requires a minimum of 3 Power Supplies Installed200 - 240 VAC Requires a minimum of 2 Power Supplies InstalledMaximum AC Power Supply Input 10 A @ 100 VAC per module7 A @ 200 VAC per moduleMaximum System Power Input 4.80 KVA @ 100 VAC4.60 KVA @ 220 VACParameter SpecificationsMaximum DC PEM Input Current 60AMaximum Power Dissipation 2400W
