Before operating the METRA GPC, the user must comply with the following safety requirements:
Check the reliability of the connection of visible ground (protective earth) conductors to the equipment, availability and
reliability of grounding contacts fastening, plugs, sockets, and connectors;
Total resistance of earthing devices: all re-grounding neutral conductor transmission line shall not exceed 10 Ohms.
The construction of connector plugs must be so that they cannot be plugged in with a higher nominal voltage than the
rated METRA GPC voltage. Prior to connecting, make sure that suitable voltage is applied according to the connector base
diagram. Avoid pulling and twisting of cables or power cords when connecting the equipment. Do not subject them to
mechanical stress & do not put loads on them. Avoid direct contact between the wire and cable with hot, wet, oily surfaces
or objects.
CAUTION!
Mounting (dismounting) of the METRA GPC is to be performed only when equipment is de-energized.
Mounting (dismounting) of the METRA GPC is to be performed only by following all the mounting (dismounting) rules
and requirements.
FORBIDDEN!
•
Do not operate the METRA GPC without reading the operating instructions.
•
Do not operate the METRA GPC without grounding.
•
Do not operate the METRA GPC when the power supply voltage is non-compliant with electrical installation code
requirements, namely for voltage 220V + - 10%.
•
Do not operate the METRA GPC without any protective elements of the rotating parts.
•
Do not open units and blocks under voltage.
•
Do not make changes in the program of the frequency converter.
•
Do not operate the METRA GPC in places where precipitation may fall on it (rain, snow, fog, dew etc.).
Mounting of the Pre-Cleaner should be performed by staff trained by the manufacturer.
8.1.Recommendations for mounting of the Metra GPC
When mounting the Pre-Cleaner, the fitter needs to have at least 47.2 in. of free space from all sides to provide ease of
maintenance.
8.2. The Metra GPC mounting procedure before operation:
Mount the METRA GPC to the location of further operation.
1.
When mounting the METRA GPC on the METRA Grain Cleaner's hopper, the METRA GPC is to be mounted on the top
of the hopper using fixing bolts.
2. When installing the METRA GPC as a single unit, it is to be mounted on a specially prepared area or bunker.
3. Install feed and discharge conveyor so as to provide a continuous separation process (The conveyors will be available
as an option, if necessary).
