14. Disposal 20

Before beginning installation procedures, these in­stallation and operating instructions should be stud­ied carefully. Furthermore, the enclosed installa-

tion and operating instructions for the standard
pump should be studied carefully. The installation

and operation should also be in accordance with lo­cal regulations and accepted codes of good practice.

1. General

GRUNDFOS E-pumps are pumps fitted with frequency-controlled
standard motors for single-phase or three-phase mains connec­tion.
The pumps have a built-in PI controller and can be connected to
an external sensor enabling control of for instance pressure, dif­ferential pressure, temperature, differential temperature or flow in
the system in which the pumps are installed. The pumps can be
set to uncontrolled operation, i.e. the pump performance can be
set according to the demand.

The pumps are typically used as circulator pumps in large heating
or cooling water systems with variable demands.

The desired value (setpoint), e.g. the desired differential pressure
if a differential pressure sensor has been installed, can be set di­rectly on the pump control panel, via an input for external setpoint
signal or by means of the GRUNDFOS wireless remote control
R100.

All other settings are made by means of the R100.
Important parameters such as actual value of control parameter,
power consumption, etc. can be read via the R100.

The pump incorporates inputs for external potential-free contacts
for start/stop and digital function. The digital function enables ex­ternal setting of max. curve or min. curve.
The pump incorporates an output for a potential-free fault, operat­ing or ready signal.

Furthermore, the pump has an input for bus communication. Via
the bus communication input, the pump can be controlled and
monitored by a building management system or another external
control system.

1.1 Twin-head pumps

Single-phase twin-head pumps do not require any external con­troller.

Three-phase twin-head pumps usually require an external con­troller. The GRUNDFOS Delta Control 2000 ME has been devel­oped for this application.

For further details about the setting and connection of three­phase twin-head pumps, see installation and operating instruc­tions for the Delta Control 2000 ME.

2. Installation

To ensure cooling of motor and electronics, the following must be
observed:

• Place the pump in such a way that sufficient cooling is en­sured.

• The temperature of the cooling air must not exceed 40°C.

• Motor cooling fins and fan bl ades must be kept clean.

When installed outdoors, the motor must be provided with a suit­able cover to avoid condensation on the electronic components,
fig. 1.

For further installation, see installation and operating instructions
for the standard pump.

2.1 Electrical connection – single-phase pumps

Note: The user or the installer is responsible for the installation of

the correct earthing and protection according to valid national and
local standards. All operations must be carried out by a qualified
electrician.

Never make any connections in the pump terminal
box unless the electricity supply has been switched
off for at least 5 minutes.

2.1.1 Mains switch

The pump must be connected to an external all-pole mains switch
with a contact separation of at least 3 mm in each pole according
to IEC 364.

2.1.2 Protection against electric shock – indirect contact

The pump must be earthed and protected against
indirect contact in accordance with national regula­tions.

Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.

2.1.3 Additional protection

If the pump is connected to an electric installation where an earth
leakage circuit breaker is used as additional protection, this cir­cuit breaker must be marked with the following symbol:

Note: When an earth leakage circuit breaker is selected, the total
leakage current of all the electrical equipment in the installation
must be taken into account.

The leakage current of the pump can be found in section

12.2 Leakage current.

2.1.4 Motor protection

The pump requires no external motor protection. The motor incor­porates thermal protection against slow overloading and blocking
(IEC 34-11: TP 211).

2.1.5 Overvoltage protection

The pump is overvoltage-protected through built-in varistors be­tween phase-neutral and phase-earth.

2.1.6 Supply voltage

1 x 200-240 V ±10%, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump

nameplate. Please make sure that the motor is suitable for the
electricity supply on which it will be used.

The wires in the pump terminal box must be as short as possible.
Excepted from this is the protective earth conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.

2.1.7 Start/stop of pump

The number of starts and stops via the mains voltage must not
exceed 4 times per hour.
When the pump is switched on via the mains, it will start after ap­prox. 5 seconds.

If a higher number of starts and stops is desired, the input for ex­ternal start/stop must be used when starting/stopping the pump.
When the pump is started/stopped via an external on/off switch, it
will start immediately.

2.2 Electrical connection – three-phase pumps

Note: The user or the installer is responsible for the installation of

the correct earthing and protection according to valid nation al and
local standards. All operations must be carried out by a qualified
electrician.

Never make any connections in the pump terminal
box unless the electricity supply has been switched
off for at least 5 minutes.

2.2.1 Mains switch

The pump must be connected to an external all-pole main s switch
with a contact separation of at least 3 mm in each pole according
to IEC 364.

2.2.2 Protection against electric shock – indirect contact

The pump must be earthed and protected against
indirect contact in accordance with national regula­tions.

Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.

Note: As the leakage current of 4 kW to 7.5 kW motors is
> 3.5 mA, these motors must be connected to especially
reliable/sturdy earth connections.

The leakage current of the individual motor size can be found in
section 13.2 Leakage current.

EN 50 178 and BS 7671 specify the following:

Leakage current > 3.5 mA:

The pump must be stationary and installed permanently. Further­more, the pump must be connected permanently to the electricity
supply or may be connected via an industrial type of plug (CEE).
The plug must comply with EN 60 309 or IEC 309.

• The earth connection must be carried out as duplicate conduc­tors.

2.2.3 Additional protection

If the pump is connected to an electric installation where an earth
leakage circuit breaker is used as additional protection, this cir­cuit breaker must be of the type:

• which is suitable for handling leakage currents and cutting-in
with short pulse-shaped leakage.

• which trips out when alternating fault currents and fault cur­rents with DC content, i.e. pulsating DC and smooth DC fault
currents, occur.

For these pumps an earth leakage circuit breaker type B m ust be
used.
This circuit breaker must be marked with the following symbols:

ELCB

2.2.6 Supply voltage

3 x 380-415 V ±10%, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump

nameplate. Please make sure that the motor is suitable for the
electricity supply on which it will be used.

The wires in the pump terminal box must be as short as possible.
Excepted from this is the protective earth conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.

2.2.7 Start/stop of pump

The number of starts and stops via the mains voltage must not
exceed 4 times per hour.
When the pump is switched on via the mains, it will start after ap­prox. 5 seconds.

If a higher number of starts and stops is desired, the input for ex­ternal start/stop must be used when starting/stopping the pump.
When the pump is started/stopped via an external on/off switch , it
will start immediately.

2.3 Other connections – single-phase pumps

Note: For single-phase TPED pumps, see section 2.4 Other con-

nections – single-phase TPED pumps.
The connection terminals of external potential-free contacts for

start/stop and digital function, external setpoint signal, sensor sig­nal, GENIbus and relay signal are shown in fig. 8.

Note: If no external on/off switch is connected, short-circuit termi­nals 2 and 3 using a short wire.

Note: As a precaution, the wires to be connected to the following
connection groups must be separated from each other by rein­forced insulation in their entire lengths:

1. Inputs (external start/stop, digital function, setpoint and sen­sor signals, terminals 1-9, and bus connection, B, Y, A).

All inputs (group 1) are internally separated from the mains­conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied by protective extra-low volt­age (PELV), thus ensuring protection against electric shock.

2. Output (relay signal, terminals NC, C, NO).
The output (group 2) is galvanically separated from other cir-

cuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.

3. Supply voltage (terminals N, PE, L).

A galvanically safe separation must fulfil the requirements for re­inforced insulation including creepage distances and clearances
specified in EN 50 178.

2.4 Other connections – single-phase TPED pumps

The connection terminals of external potential-free contacts for
start/stop and digital function, external setpoint signal, sensor sig­nal, GENIbus, relay signal and communication cable are shown in
fig. 9.

Note: If no external on/off switch is connected, short-circuit termi­nals 2 and 3 using a short wire.

Note: As a precaution, the wires to be connected to the following
connection groups must be separated from each other by rein­forced insulation in their entire lengths:

1. Inputs (external start/stop, digital function, setpoint and sen­sor signals, terminals 1-9, and bus connection, B, Y, A).

cuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.

3. Supply voltage (terminals N, PE, L).

4. Communication cable (8-pin male socket).
The communication cable is connected to the socket in group

4. The cable ensures communication between the two pumps,
whether one or two pressure sensors are connected, see sec­tion 2.6 Signal cables.

The selector switch in group 4 enables changeover between
the operating modes “alternating operation” and “standby op­eration”. See description in section 3.2.1 Additional operating
modes – single-phase TPED pumps.

A galvanically safe separation must fulfil the requirements for re­inforced insulation including creepage distances and clearances
specified in EN 50 178.
