4.5 Control Cable Connections
CAUTION
The control and power supply cables must be laid separately. They must not be fed through
the same cable conduit / trunking.
Use screened cable for the control lead.
Feed the control cable into the inverter via
the appropriate gland hole
.
Connect the
control wires in accordance with the
information in Figures 4, 5 and 6, having first
unplugged connector block PL800 from the
PCB (CS B only).
IMPORTANT:
A wire link
must
be fitted
between control terminals 5 (DIN1) and 1
(P10+) if it is required to start the inverter
from the control potentiometer R314, or the
analogue input.. The wire link must be
removed when operation via a run/stop
switch is required.

Note that the optional
potentiometer fitted as an
analogue set point shown in
Figure 4 & 5 assumes that
jumper JP304 is connecting 0V
(pin 2) to AIN- (pin 4).
+15V can be used as an
alternative to P10+ for the
digital inputs.
Plug the connector block back into the PCB
(CS B only), refit the cover and tighten the
four securing screws.
