Externally soundproofed cab made of steel and coated with epoxy powder paint to ensure optimal corrosion resistance. The cab is RAL6017 green, while the roof, base, and front panel are RAL7012 gray. It is equipped with sound-absorbing material that provides high acoustic insulation. Access for routine and non-routine maintenance is facilitated by sturdy, lockable access doors. Inside the enclosure is a residential-grade muffler with a noise reduction of 35 dB(A). The central lifting hook is certified. Fresh air intake and hot air exhaust occur vertically through special sound-insulating ducts.

ELECTRICAL PANEL
AUTOMATIC
The EY-R20P model’s electrical panel is designed to ensure a high level of control and safety. At the heart of the system is the ComAp AMF25 control unit, featuring an ON/OFF selector switch and protected by a viewing window for safety and visibility. It includes an integrated battery charger and periodic testing to monitor the system, with connection instructions for the power grid.
Housed in a durable IP44-rated metal enclosure, the panel features 8 configurable outlets: 2 5-pole 400V CEE 32A outlets, 2 5-pole 400V CEE 16A outlets, one 3-pole 230V CEE 16A outlet, and 3 230V Schuko outlets, each with thermal-magnetic protection and a general residual current device (RCD).
Additional features include a USB port and a 230V 16A CEE plug for the battery and heater. Circuit breakers protect the auxiliary circuits, while an emergency stop button and grounding terminal ensure safety.
An electronic float switch monitors the fuel level, and an alarm system signals anomalies such as voltage and frequency fluctuations, low oil pressure, high water temperature, alternator failures, and low fuel. Finally, digital gauges are provided for oil pressure and engine temperature.
