(1) ATV<strong>38</strong>HC10N4X to C33N4X: Line choke compulsory.<br />
ATV<strong>38</strong>HU18N4 to D23N4: Line choke if necessary.<br />
(2) Fault relay contacts for remote signalling of <strong>drive</strong> status.<br />
(3) Internal + 24 V. If an external + 24 V supply is used, connect the 0 V from that source to the COM terminal,<br />
do not use the + 24 terminal on the <strong>drive</strong>, and connect the common of the LI inputs to the + 24 V of the<br />
external supply.<br />
(4) R2 reassignable relay.<br />
Note:<br />
Fit interference suppressors to all inductive circuits near the <strong>drive</strong> or connected in the same circuit, such as<br />
relays, contactors, solenoid valves, fluorescent lighting, etc.<br />
Components which can be used in association with the <strong>Altivar</strong>: see catalogue.<br />
