Figure 4 – Connection of the refrigerated display cabinets
Before connecting the refrigerated display cabinets to a socket, make sure that the limit values of the supply voltage
correspond to the voltage value indicated on the marking plate of the refrigerated display cabinets (nameplate). To ensure
reliable operation of the refrigerated display cabinets, use the mains with the range of voltage supply deviations from -10%
to +10 % of the rated value. The refrigerated display cabinets must be connected to a properly grounded mains socket. The
compliance with this requirement is MANDATORY for safe operation of the equipment.
The cross-section of conductive wires to the connecting point of the refrigerated display cabinets is rated for the operating
current of the refrigerated display cabinets. The socket must be located in an easily accessible place for quick connection
of the product and must ensure a reliable contact of the conductive parts of the plug and the socket (Fig. 4). An inadequate
contact may cause a malfunction of the refrigerated display cabinets or a fire.
ATTENTION! Do not connect the refrigerated display cabinets to the mains via extension cords or tees that can
not provide a reliable contact connection and have insufficient cross-section of wires for operating the refrigerated
display cabinets.
