2-7.3. Connecting the Power Equipment
Proceed as follows:
• External Mains
o Connect Mains power to the Mains Circuit Control Box (MCC)
• Uninterruptible Power Supply (UPS)
o Connect the MCC to the UPS.
• If any doubt concerning grounding arises, ask for a ground test performed by a qualified
electrician.
2-7.4. AC Power Supply Setup
CFN PLUS can be fed either 110 VAC or 220 VAC. The Mains cable is first connected to the
terminal block. Between the terminal block and transformer the system uses a Line Filter in order to
attenuate conducted radio frequencies - RFI, electromagnetic interference (EMI) - between the line
and the equipment (see Figure 2-8). AC power is then supplied to an AC/AC High to Low
Transformer – 110/220 VAC to 25 VAC. The transformer requires jumpers' setup for either 110
VAC or 220 VAC Mains input, as shown in Figure 2-9. A settings label is also found on top of the
transformer.
