Connection To Energy Sources; Connection To Electrical System; Connection To The Hydraulic System - OMAC B Series Operation And Maintenance Manual

• prepare aqueous solution of sodium hypochlorite (5%);
• clean all surfaces in contact with the chemical process fl uid carrying out the operation for at least 15 minutes;
ATTENTION
Sanitise all surfaces in contact with the chemical product proceeding for at least 15 minutes.
• with cold running water, rinse all the previously cleaned surfaces, making sure all traces of sanitiser are removed.
e) Reassemble the previously removed mechanical elements following the indications contained in Chapter 5, section 5.8, 5.9, 5.10 of this UMM. After
having assembled the clean pump components, remove the protective sheets, placed on the electric panel, electric motor and cable shunt/connection
boxes and subsequently connect to the energy sources, disconnected before starting manual cleaning.

3.5 Connection to energy sources

Below there are the procedures for connecting the LDPU to the energy sources, needed for its proper operation.
3.5.1 Connection to the electrical system
Connection to the electrical mains must be carried out by the operator responsible for the assembly/installation activities, in compliance with the strictest
technical standards, the connection must be carried out after the hydraulic connection. This personnel must have full knowledge of the rules for use and
operation of electrical equipment supplied with the LDPU.
The Customer must organise the plant layout so as to provide:
• a manual supply sectioning device,
• over-current and overload protection,
• devices that prevent spontaneous restarting.
Before carrying out the connection one must ensure that:
• the frequency and voltage of the Customer plant corresponds to the data carried in the "technical sheet" of the LDPU;
• The material used for the electrical connection has an IP degree suitable for the environment in which it is installed, in order to prevent the
conductors from overheating.
The connection of cables to the terminal board can be carried out both in triangle or star, complying with the data carried on the motor nameplate accor-
ding to the mains voltage.
The connection of electric wiring can take place as follows:
1) LDPU with electric panel;
2) LDPU without electric panel;
In particular, in case 1), in presence of the electric panel, the operator must carry out the following operations:
• section the electric mains in order to insulate the sockets from the industrial electricity supply;
• connect the plug;
• power the electricity sockets;
this way even the LDPU electric control panel is powered.
ATTENTION
Operate with caution: the LDPU and the control actuators are powered electrically.
In case 2), in absence of the electric panel, the operator must see to power the electric motor on the basis of the indication contained in the electric motor
Use and Maintenance Manual (UMM available in electronic version on the Internet websites of the relative manufacturers).
One must also provide earthing for the motor, using the jack provided on the motor and an adequate section conductor: the connection must be carried
out with a type NO7Vk mm
ATTENTION
Before carrying out any operation, check that the features of the distribution network (voltage and frequency) correspond to the data on the motor plate
or electric panel.
ATTENTION
O.M.A.C. s.r.l. is NOT responsible for damages caused by incorrect installation of the electric energy supply, in case of failure to comply with the technical
standards in force.

3.5.2 Connection to the hydraulic system

Before going further one must check compliance with the indications of section 3.3.2 of this chapter.
If the indications above have been observed, one can proceed with the following activities:
a) connection of mechanical seals fl ushing;
b) connection of pumping chamber cover heating/cooling;
c) connection of pumping body heating/cooling.
ATTENTION
It is essential, as indicated in section 3.3.1, before carrying out the hydraulic connections, to wash the plant - in order to clean the pump -, and the hydrau-
lic connection lines, from dirt residues such as dust, sand, process scraps, etc.
