When this pump unit is used as a stand alone pump it complies with: Machinery Directive
98/37/EC EN60204-1, Low Voltage Directive 73/23/EEC EN61010-1, EMC Directive 89/336/EEC
EN50081-1/EN50082-1.

When this pump unit is to be installed into a machine or is to be assembled with other
machines for installations, it must not be put into service until the relevant machinery has been
declared in conformity with the Machinery Directive 98/37/EC EN60204-1.

T wo year warranty

Watson-Marlow Limited warrants, subject to the conditions below, through either Watson-Marlow Limited, its subsidiaries, or its
authorised distributors, to repair or replace free of charge, including labour, any part of this product which fails within two years of
delivery of the product to the end user. Such failure must have occurred because of defect in material or workmanship and not as
a result of operation of the product other than in accordance with the instructions given in this manual.

Conditions of and specific exceptions to the above warranty are:

• Consumable items such as tubing and rollers are excluded.

• Products must be returned by pre-arrangement carriage paid to Watson-Marlow Limited, its subsidiaries, or its authorised

distributor.

• All repairs or modifications must have been made by Watson-Marlow Limited, its subsidiaries, or its authorised distributors or
with the express permission of Watson-Marlow Limited, its subsidiaries, or its authorised distributors.

• Products which have been abused, misused, or subjected to malicious or accidental damage or electrical surge are excluded.

Warranties purporting to be on behalf of Watson-Marlow Limited made by any person, including representatives of Watson-Marlow
Limited, its subsidiaries, or its distributors, which do not accord with the terms of this warranty shall not be binding upon Watson­Marlow Limited unless expressly approved in writing by a Director or Manager of Watson-Marlow Limited.

Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to
health must be decontaminated before it is returned to Watson-Marlow or its distributor.

A certificate included at the rear of these operating instructions, or signed statement, must be attached to the outside of the shipping
carton.

This certificate is required even if the pump is unused. If the pump has been used, the fluids that have been in contact with the pump
and the cleaning procedure must be specified along with a statement that the equipment has been decontaminated.

Safety

In the interests of safety, this pump and the tubing selected should only be used by competent, suitably trained personnel after they
have read and understood this manual, and considered any hazard involved.

Any person who is involved in the installation or maintenance of this equipment should be fully competent to carry out the work. In
the UK this person should also be familiar with the Health and Safety at Work Act 1974.

Fundamental work with regard to lifting, transportation, installation, starting-up, maintenance
and repair should be performed by qualified personnel only. Make absolutely sure that no voltage
is applied at all whilst work is being carried out on the geared motor. The motor must be secured
against accidental start up.

500 and 600 series close coupled pumps

Details on the use, operation, maintenance and spare parts for the 500 and 600 series close coupled pumps can be found in the
accompanying manual PB 0279.

T rio cose coupled pump operating instructions

Trio close coupled pumps combine a pumphead, motor/ gearbox and integral inverter into a robust IP55 pump.

500 and 600 series Trio close coupled pumps

This equipment contains hazardous voltages (at mains potential) inside the pump. If access is required, turn
the power off and wait one minute so that the dc-link capacitors can discharge. Some parameter settings
can start the motor automatically after a mains failure. The Trio inverter is not to be used as an emergency
stop mechanism, a circuit breaker must be used.

Wiring connection details

Remove the four M4 cross head screws on the Trio’s cover to access the electrical terminals (see Fig. 2).

Note: A ‘drip loop’ is recommended when connecting the mains and control cables (see Fig. 1).

Fig. 1 Connecting mains cables and control cable with a drip loop.

The printed circuit board is particularly sensitive to static electricity. For this reason, avoid touching the
boards or components with your hands or metal objects.

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.

Fig 2. Electrical connection drawing

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.
