7.2.1 Power supply connection
Connect the on-site 4-wire cable (L1, L2, L3, PE)
for the supplying network to the main switch, in
accordance with the wiring diagram.
7.2.2 Fault signal/run signals connection
A signal can be taken from the terminal strip for
the fault signal/run signal via a potential-free
contact in order to indicate a fault/operation
(see wiring diagram).
Potential-free contacts, max. contact load
250 V~/1 A
Warning! Danger of electric shock!
There is a potentially fatal voltage on these ter-
minals, even when the main switch is turned off.
8 Commissioning
WARNING! Risk of fatal injury!
Commissioning by qualified personnel only!
Improper commissioning poses a risk of fatal
injury. Have commissioning performed by quali-
fied personnel only.
DANGER! Risk of fatal injury!
When working on the open switchgear, there's a
danger of electric shock from touching the live
components.
This work must only be carried out by qualified
personnel!
We recommend that you have the switchgear
commissioned by Salmson customer service.
Before switching on for the first time, the on-site
wiring must be checked, in particular the earthing.
Tighten all terminals prior to commissioning!
8.1 Switchgear settings
After switching on the main switch and expiration
of the start sequence in the display and of the sig-
nal lamps, the switchgear is ready for operation
and factory preset.
The factory settings can be restored by Salmson
customer service.
To ensure correct operation it is necessary to
implement and/or check certain settings in the
menu
Menu 1.2.1.1:
Setting of the supply voltage in volts.
Menu 1.2.1.2:
Setting of the pump's rated current. Information
relating to the pump's rated current is to be
inferred from the pump's rating plate.
50
Menu 1.2.1.3:
Display of the pump's capacity. The value used for
the capacity results from the set values for voltage
and current under menu 1.2.1.1. and menu 1.2.1.2.
Menu 5.2.1.0:
Setting of the transformer type (primary current
measuring range). Information relating to the
transformer type can be found on the trans-
former's rating plate.
NOTE:
If the measuring line has not only been run
through the transformer but also wrapped around
it, the current value of the transformer is to be
halved for each wrapping.
Example:
The measuring line has been wrapped twice
around a 100/5A transformer.
1 wrapping = 50/5A transformer
2 wrappings = 25/5A transformer
A 25/5A transformer should therefore be set in the
menu.
Menu 3.1.0.0:
Setting of the operating mode to "Automatic on"
(automatic pump operation).
CAUTION! Risk of malfunctions!
If "Automatic off" is set, automatic mode is not
possible. The pump can only be switched on man-
ually.
8.2 Checking the motor direction of rotation
By briefly switching on the pump, check that the
direction of rotation of the pump is correct. When
the pump motor runs out, compare the direction
of rotation of the fan wheel and the direction
specified on the pump housing.
If the direction of rotation of the pump is wrong,
swap over any two phases of the power cable.
9 Maintenance
Have maintenance and repair work carried out
by qualified skilled personnel only!
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock
when working on electrical equipment.
• The switchgear should be electrically isolated
and secured against unauthorised switch-on
during any maintenance or repair work.
• Any damage to the connection cable should only
ever be eradicated by a qualified electrician.
• The switchbox must be kept clean.
• Visual inspection of the electric system parts in
the switchbox
