• Main disconnecting switch with door lock;
• Transformer for power supply of auxiliary circuits;
• Contactor (for each motor);
• Exchanger;
• Protection degree IP 55

INPUTS
• No. 6 extra low voltage inputs for:
– Emergency stop SL / SP STOP (e.g., float switches for protection from dry operation), active in
both AUTOMATIC and MANUAL modes;
– Functional start and stop SL / SP 1 (e.g..: control float switches);
– Maximum level alarm SL / SP MAX;
– Engine block due to temperature sensor tripping

CONTROLS AND SIGNALS
• Selector switch for OFF-AUTOMATIC-MANUAL operation;
– No. 5 indicator lights for the signaling of:
– Presence of power supply;
– Motor pump 1 or 2 running;
– Motor protection tripping 1 or 2

PROTECTION AND ALARMS
