4.3 Accessories
The following options can be ordered :
• Motor protection circuit breaker • pressure measurement kit •
round mating flanges for welding • anti-vibration sleeves, etc...
5. INSTALLATION
5.1 Assembly (See FIG. 1)
- Make sure that the circulator is accessible.
- Direct connection to vertical or horizontal piping.
- Motor shaft must be horizontal.
- Respect flow direction indicated by an arrow on the flanges (or on
casing).
- Install valves on either side of the inlets/outlets to facilitate
removing the circulator or any other intervention.
Do not insulate the motor casing. If the body is insulated,
make sure that the condensation drainage holes are free.
5.2 Electrical connections (See FIG. 2)
The electrical connections must be made by a qualified
electrician in compliance with local regulations.
All electrical information relating to the circulator are given on the
rating plate.
- Install a main switch.
- Respect the required operating voltage and install 10 A protection
for the motor.
- Connection of the connection box via stuffing box, entry on left or
right.
Use a 3- or 4-wire cable (2 or three phases + ground) to connect the
power supply to the terminals.
• THREE-PHASE: L1 – L2 – L3 + GROUND.
Terminals 10 and 15 (dry contact with 250 V – 1 A opening) for
remote indication of fault information.
The power supply cable must not be in contact
CAUTION !
with the piping or the pump: make sure that it is
not exposed to any humidity.
The three-phase circulator is supplied set to 400 V. Change of
voltage must be done with POWER DISCONNECTED.
5.3 Voltage selection – three-phase motor
• 3-PHASE 400 V (415 V): standard delivery.
• 3-PHASE 230 V (240 V) (speed selector three-phase 230 V sold as
an additional accessory - see FIG. 2b).
Terminals 10 and 15 (NC dry contact, 250 V, 1 A) for remoting of a
fault reporting signal to a centralized location.
5.4 Speed selection
SXS 32-25M : 3 speeds are possible by revolving selector in the
terminal box.
SXS 40-40M : 2 speeds are possible by plug-in selector in the terminal
box.
Other models : 3 speeds are possible by plug-in selector in the
terminal box.
- Remove the cover of the terminal box.
- put the reference mark of the selector (revolving or plug-in)
opposite selected speed.
- Close again the lid of the terminal box.
Any voltage error would result in damage to the
CAUTION !
motors.
