IMTP 2.2 - ITTP 2.2/4/5.5/7.5
ENG
§
Optional 4 - only for IMTP-ITTP2.2:
flow switch connection
to detect the minimum flow stop in
mechanical mode: connect the two terminals of the flow switch on +15V (1 of J8, fig. 5) and PS2 (3 of J8,
fig.5) on the Logic board; the two contact can be inverted;
§
Optional 5: for IMTP-ITTP2.2 there is relay output contact (1, 4 of J11 fig.5, MOT.ON-COM) 2Ampere Ð
250Vac max. that close when the motor is working; for ITTP4.0-5.5-7.5 between contacts MOTOR ON
and ÒÐÒ of J10 (fig.8) there is a 12Vdc 200mA max. signal when the Motor is working;
§
Optional 6: for IMTP-ITTP2.2 there is relay output contact (2, 4 of J11, ALARM-COM, fig.5) 2Ampere Ð
250Vac max. that close when there is an Alarm condition; for ITTP4.0-5.5-7.5 between contacts ALARM
and ÒÐÒ of J10 (fig.8) there is a 12Vdc 200mA max. signal when there is an Alarm;
§
Optional 7: for IMTP-ITTP2.2 you can supply a 12Vdc - 200mA max. external Fan, connecting it between
5, 6 of J8 (FAN-GND, fig.5); for ITTP4-5.5-7.5 you can supply a 12Vdc - 200mA max. external Fan,
connecting it between contacts VENT and ÒÐÒ of J10 (fig. 8);
§
Connect the two
line wires
and ground on L, N, GND for single-phase Inverter IMTP2.2 (fig. 6) or the
three line wires and ground on L1, L2, L3, GND for ITTP2.2 /../7.5 (fig. 7, 9); use the up-level connector
extension for ITTP4.0W, ITTP5.5W, ITTP7.5W;
§
Reconnect J1 and J2 connectors for IMTP-ITTP2.2 (fig.5) and J9 for ITTP4/../7.5 (fig.8) if previously
disconnected, making sure they are firmly fixed; donÕt forget the clamp on J9 for ITTP4/../7.5 (fig. 8);
·
Replace and close the box using the previously removed screws;
·
Connect the power supply plug to the electric line.
Before a possible reopening of the inverter box, after functioning, switch off the voltage supply
and wait at least 1 minute to be sure that the capacitors are completely discharged (danger:
contact with electric high voltage parts).
