3.10 INPUT/OUTPUT CONTROL CONNECTIONS
To avoid 'interference pick up' all input and output control cables should be kept as short as
possible and should wherever possible, be shielded. If noise free lines cannot be
guaranteed, an interposing relay with suitable suppression must be used, this should be
mounted as close to the
EnviroStart
as possible.
3.11 EMISSIONS
EnviroStart
units produce relatively low Radio Frequency Interference (RFI) compared with
frequency inverters and no external filters are required in normal circumstances. (See also
Section 3.3 – Harmonics).
3.12 CABLE AND INPUT FUSE RATINGS
Incoming fuses and power cables should generally comply with the ratings as shown in the
table below. It is recommended that all cable be tri-rated compliant with BS 6231 and that all
fuses be motor rated, bolt fitting, compliant with BS 88 Part 2. (It is not necessary to use
motor rated fuses if the unit is being used in DPR Mode).

The above detail refers to new installations, where the
EnviroStart
is fitted into an existing
installation; cable should be rated according to the fuses already fitted.
