HYDRAULIC CONNECTION OF THE CONDENSATE DRAIN

The connection of the condensate drain must be carried out as decided during the design
stage.
SUPPLY
The condensate drain pipe is connected to the collection tank.
The piping is wound and the bottom of the machine.
The length of the piping brings the drain just outside the machine. A circular cut-out shape
must be opened on the base. (Round cut-out shapes can be found on the right and the left.
It's for the installer to decide which side to use).
The piping is made of plastic, with an internal diameter of Ø 19 mm.
The condensate drains by gravity.
BY THE INSTALLER
Set up a trap (A) in the vicinity of the machine, as shown in the figure.
Fill the trap with water.
Ensure a 2 - 3% gradient of the pipe down towards the drain.
Keep the same internal diameter for drain pipes of up to 4 - 5 metres. For greater lengths,
increase the section of the drain.
UNDER
OVER
A
The condensate drain can be identified from the plate affixed directly
inside the machine
The connection pipes must be suitably supported so that they do not weigh down on the
machine.
OBLIGATION
NO PART OF THE DRAIN LINE SHOULD BE UPHILL.

ELECTRICAL CONNECTIONS

The electrical connections of the machine must be defined during the system design.
DANGER
The electrical connections must only be designed and
completed by personnel with precise technical competence or
particular skills in the field of activity.
Before proceeding, personnel must disconnect all power supply
sources, making sure that no one may inadvertently re-connect
them.
UM_w-MEXT_01_Z_10_20_ML
The characteristics of the power supply network must comply with the IEC 60204-1
standards and the local standards in force, and be adequate for the absorption
requirements shown in the wiring diagram.
The machine must be connected to a single-phase power supply, or to a TN(S) type three-
phase power supply (optional). Refer to the electrical diagram.
Should the installation of a circuit breaker be envisaged in the electrical system, it must be
type A or B.
Refer to local bylaws. Only power the system if the hydraulic circuit is charged.
In accordance with the IEC 60204-1 standard, the handle of the circuit breaker must be
easy to access and at a height between 0.6 and 1.9 metres from the floor. The power
supply must never be excluded, except during maintenance.
2.5.1
Use a multipole conductor with protective sheath. The cable section depends on the
DL
maximum absorbed current of the machine (A) as shown in the dedicated wiring diagram.
For feeding the power cables inside the machine use the holes provided at the base by the
Manufacturer (UNDER/OVER/DISPLACEMENT version).
Fix the cables to the internal machine riser using cable ties. Do not touch hot or sharp
surfaces.
Connect the power cable to the terminals of the door locking switch and to the ground
terminal.
The power cable must not be placed into the machine cable ducts.
A
2.5.2
The control circuit is shunted off the power circuit from inside the switchboard.
The auxiliary connections can be found in the terminal board contained in the electrical
panel of the machine.
Connections required:



It is recommended that any auxiliary connection cables are separate from power cables.
Otherwise, screened cables should be used.

OBLIGATION
The electric power supply line must include a general circuit
breaker for the disconnection of the machine from the power
source.

MACHINE POWER SUPPLY

The electrical panel is always positioned in the upper section of the machine
as shown in the figures.
