In case the unit is moved at a temperature of approx
or below 0°C (32°F), you must always make sure that
the the unit has been fully emptied for water. If this is
not the case, you may damage the unit.
6.3. Electrical installation
6.3.1. Power supply
Connection instruction is mounted on the cables.
The phase order is subordinated.
6.3.2. Earth leakage circuit breaker (ELCB)
When using an earth leakage ircuit breaker (ELCB) also
known as a residual current device (RCD) or a residual
current circuit breaker (RCCB) in a system that incorpo-
rates a variable speed drive connected to 3 phase 400 V.
The trip level of the ELCB has to be 300 mA.
(30 mA used in house hold will malfunction due to earth
leakage).
6.3.3. Service switch
The unit must always be connected to the main sup-
ply through a separate service switch.
NB! Installation must always be in accordence with
local legistration.

Connecting cable.
Observe the following when using E.l.c.b:
• Installation of E.l.c.b only between supplying mains and controller.
• The E.l.c.b can be activated by:
- capacitive leakage currents between the cable screens during operation (especially with long,
screened motor cables)
- connecting several controllers to the mains at the same time
- RFI filters
6.4. Safety relay
The mainstation is equipped with a safety relay. The
relay breaks the main supply to the motor inverter
when activated. Please see enclosed electrical sche-
matic for connection terminals. If a safety/emergency
stop of the unit is needed, connection S_in1, S_IN2
and S_Reset must be used.

6.5. Mounting of slave for additional I/O´s
1st slave
The slave comes with a bracket so that it can be
mounted inside the cabinet of Hybrid Foamatic Main-
station. Furthermore it comes with an Ethernet plug
that has to be mounted at the bottom of the electrical
box, an Ethernet cable for connection between the
slave and the plug at bottom of the electrical box, and
an Ethernet cable from the plug at the bottom of the
electrical box to the switch (K108) inside the electrical
box.
The 1st slave shall have its electrical connection at
terminal X1.1, X1.2 and PE as illustrated in drawing
number 110005376 page 1 of electrial diagrams.
The Ethernet cable must be connected on the switch
(K108) as shown in drawing number 110005376 page
8 of electrical diagrams.
2nd slave
The slave comes with a bracket so that it can be
mounted on the wall if desired. The 2nd slave has
its own power supply and must be connected to a
nearby power source. It too comes with an Ethernet
plug that has to be mounted at the bottom of the elec-
trical box, an Ethernet cable for connection between
the slave and the plug at bottom of the electrical box,
and an Ethernet cable from the plug at the bottom
of the electrical box to the switch (K108) inside the
electrical box.
The Ethernet cable must be connected on the switch
(K108) as shown in drawing number 110005376 page
8 of electrical diagrams.
6.6. Water connection
• Before the unit is connected to
the water supply pipe, the supply
line should be rinsed carefully in
order to remove coarse impuri-
ties and metal shavings.
• The connection for water must
be made at the top of the unit.
(see layout drawing).
• Minimum diameter of the supply
pipe must be at least Ø38 exter-
nal (ø35mm internal).
• The unit must be fitted with a
closing valve for water on the
inlet (see drawing 110005285 on
page 14).
