Control Cable Connections - Siemens COMBIMASTER Reference Manual

COMBIMASTER & MICROMASTER Integrated
REFERENCE MANUAL

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.
