Installation and operating instructions Salmson SXS / NSB-S 35
English
• Install appropriate flat gaskets between pump and counter flanges.
• Tighten the flange bolts across diagonals in two steps to the prescribed tight-
ening torque (see Table 7.1.2).
• Step 1: 0.5 x permissible tightening torque
• Step 2: 1.0 x permissible tightening torque
• Check the flange connections for leaks.
7.2 Electrical connection
DANGER! Danger of death!
Improper electrical connections pose a risk of fatal injury due to electric shock.
• Only allow the electrical connection and all associated activities to be made
by an electrician approved by the local electricity supplier and in accordance
with the local regulations in force.
• Before working on the pump, all poles of the power supply must be discon-
nected. Because voltages hazardous to persons persist for some time
(in capacitors), no work may be commenced on the module until 5 minutes
have elapsed (applies only to 1~ systems). Check to ensure all connections
(including potential-free contacts) are voltage-free.
• If the module/terminal box is damaged, do not operate the pump.
• If the setting and operating elements on the module/terminal box are unduly
removed, there is a danger of electric shock by touching the electrical com-
ponents located inside.
CAUTION! Risk of damage!
An incorrect electrical connection can cause damage to property.
If the wrong voltage is applied, the motor can be damaged!
• The current type and voltage of the mains connection must correspond to the
specifications on the name plate.
• The electrical connection must be established via a fixed connection line
equipped with a connector device or an all-pole switch with a contact opening
width of at least 3 mm.
