Programming and Scaling
The KWH-400 is direct connected up to
500V with 5 Amp CT inputs. The CT ratio
is field programmable without any
special tools via DIP switches mounted
on the underside of the unit behind a
tamper proof label.
Once the CT ratio has been
programmed, the scale factor should be
adjusted on the front display. A self-
adhesive decimal point can be affixed in
the appropriate position on the
mechanical counter.

It is recommended that all voltage lines are fitted with 1 Amp HRC fuses. For safety
reasons, CT secondary connections should be grounded according to local codes of
practice.
