Electrical Connections
For products supplied without pre-fitted plugs, it is recommended
that all electrical connections are carried out by a qualified
electrician.
The product covered by this manual normally requires a single phase A.C. supply,
which may be "Live to Neutral non-reversible", "Live to Neutral reversible" or "Live to
Live". Some models may be ordered for 3-phase use, which may be with or without
neutral.
Check the product rating label before connection. The supply voltage should correspond
with the voltage on the label and the supply capacity should be sufficient for the current
on the label.
The supply should be fused at the next size equal to, or higher than the current on the
label. This manual contains a table of the most common fuse ratings.
l
When the mains cable is factory-fitted / supplied, internal fuses are also fitted. It is
essential that the operator ensures that the power supply is correctly fused.
l
Products with a factory fitted supply cable but without a plug are designed to be
wired directly to an isolator or fitted with a line plug compliant with the customer's
local regulations and supply.
l
Products without a factory-fitted supply cable require a permanent connection to a
fused and isolated supply. The product's electrical component access panel should
be temporarily removed, and connections made to the internal terminals / fuse
holder.
When connecting the product to the power supply, the plug or
isolating switch should be accessible, easy to remove / operate,
and within reach of the operator.
Note:
The supply MUST incorporate an earth (ground).
