Removal of 'Y' Capacitor Link
To use the inverter on
ungrounded supplies the 'Y'
capacitor (cap) link must be
removed as follows:
1. Ensure the inverter has
been disconnected from
all power supplies.
2. Locate the 'Y' Cap cover
on the left side of the unit
near the rating label.
3. Carefully remove the 'Y'
Cap cover.
4. Cut the 'Y' Cap link with
an appropriate pair of
wire-cutters.
5. After removal of the cover
the degree of protection is IP00.
Access to the power and motor terminals
Please refer to the photographs showing the
Power Terminal connections and the Control
Terminal connections on the inside of the
back cover of this manual.
Connect the power and motor connections
as shown below.
For access to the DC+/DC- terminals the cut-
out cover must be removed. The terminal
connection consists of two spades
measuring 6.3 mm by 0.8 mm. With the cut-
out cover removed and not connections fitted
to the spades, the inverter has only IP00
protection.
The connection of the DC link can be used
for two inverters, with two motors which work
on a revolving advertising media or similar
application:
one inverter is in motor mode and the other
is in regenerative mode.
