Mains cable connections
Ensure that the power source supplies the correct voltage and is designed for the rated current. Use a circuit-breaker with a 10A
current rating between the power supply and Trio. Use Class 1 60/75°C copper wire only with a cross sectional area of 1mm. If
crimp terminals are used they must be insulated. If crimps are not used, the strip length must not exceed 5mm. Feed the power
cable into the inverter via the gland hole nearest to the motor shaft using a PG16 gland. Connect the power leads to terminals L1,
L2 and the separate earth. Use a 4-5mm cross head screwdriver to tighten the terminal screws.

Ensure that the following tightening torques are used: Access cover retaining screws:
2.5Nm, Gland hole covers: 1.0Nm, Mains connector screws: 1.0Nm, Control connector PL700: 0.4Nm.
Check the supply voltage is correct for the inverter used by referring to the rating label.
Control cable connections
The control and power supply cables (max 1mm diameter) 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 (see Fig. 2). Connect the control wires in accordance with the
information in Fig. 3 and 4 (also see Fig. 1).
IMPORTANT:
A wire link will have been factory fitted between control terminals 5 (DIN1) and 1 (P10+) to enable the Trio to
operate when control potentiometer R314 is used. 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 Fig. 3 assumes that jumper JP304 is connecting 0V
(pin 2) to AIN- (pin 4). Also, P15+ can be used as an alternative to P10+ for the digital inputs.
