Electrical Installation; Power Supply; Earth Leakage Circuit Breaker (Elcb); Service Switch - Ecolab Hybrid Foamatic MA2CM Mode D'emploi

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 MA
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 MA and 1st & 2nd MAPD
The slave comes with a bracket so that it can be
mounted on the wall if desired. The 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 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 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 impurities 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 external
(ø35mm internal).
• The unit must be fitted with a clos-
ing valve for water on the inlet (see
drawing 110005285 on page 14).
