Refer to Chapter 11: “Technical Specifications” - Environmental Details. (For operation above
the quoted temperature, derating of the converter may be necessary. Refer to Eurotherm Drives
for further information.)
The drive is force-cooled using the fan units supplied with the drive.
The Converter gives off heat in normal operation and must therefore be mounted to allow the
free flow of air through the air entries and exits. Maintain the minimum air clearances (as a
general rule allow at least 150mm (6 inches) of clear space above and below the drive for free air
flow) to ensure that heat generated by other adjacent equipment is not transmitted to the
Converter, be aware that other equipment may have its own clearance requirements. When
mounting two or more 590 Series Converters together, these clearances are cumulative.

The fan unit supplied should be installed on the cubicle, with or without ducting (refer to the

A 3-phase contactor should be connected in the main ac power supply
connections with a rating suitable (AC1) for the controller concerned.
The contactor does not switch current and is primarily for disconnection and sequencing of the
power bridge. The main contactor must be energised directly from the controller by connecting
the coil to terminals D5 (Line) and D6 (Neutral). No additional series contacts or switches are
permitted since they will interfere with the sequencing of the controller and cause unreliability
and possible failure.

Refer to Figure 3-3.
The main ac power is connected to busbar terminals L1, L2 and L3, there
is no specific phase connection to these three terminals as the controller is phase rotation
independent. The connections must be made via the main contactor and the ac line choke.
High speed, semi-conductor fuses are provided in the unit to protect the thyristor stack in case of
direct ouput short circuits. You should provide suitable branch protection fuses to protect
cabling.
Fit a 3-phase ac line choke in series with the incoming main 3-phase ac power supply.
(Eurotherm Drives can provide suitable choke for this duty, mechanically designed to connect
directly to the controller ac supply terminals.) The choke should be connected between the
controller and the ac contactor for optimum protection and safety.
The choice of ac or dc contactors is a user preference. Eurotherm Drives prefer ac contactors as
they isolate the converter and motor when not in use. The only restriction on the use of a dc
contactor is that an interlocking contact should be provided into the Enable input.

The motor armature is connected to busbar terminals A+ and A-. If a DC
contactor is used the poles should be interposed between the controller
terminals and the motor terminals.
When the controller is operating in a regenerating mode for extended periods acting as a load
generator for another machine, it is advisable to fit additional protection in the armature circuit.
A DC fuse or a high speed circuit breaker will provide this protection, if in doubt consult the
Eurotherm Drives Engineering Department.

An external field supply is required to the controller under all
circumstances. Connect this supply to terminals FL1 and FL2. The
magnitude of this voltage is determined by the desired field voltage. The

supply from the Red and Yellow phases of the main power supply, with the
Red phase connected to terminal FL1 and the Yellow phase connected to
