Devices and Solutions for Protection
Passive Safety Devices
The equipment includes the following safety devices and features:
• Fixed guards close to the moving parts
•
External fairing with fixed access doors (if equipped)
• Safety signs corresponding to the guards on the equipment
Active Safety Devices
The equipment includes the following active safety devices:
•
Maximum safety pressure switch for each automatic reset compressor (PSH) or for specific versions with
safety pressure switch for each manual reset compressor (PZH)
•
Safety valve on the MT and LT circuit low-pressure side (if equipped)
• Safety valve(s) on the intermediate receiver
•
Safety valve on the high-pressure side, (if equipped)
The valve calibration is shown on the valves themselves and is based on the EN 13136 standard.
ATTENTION: It is strictly forbidden to modify the calibration of the safety pressure switch and/or to
inhibit its operation.
Protection Systems
The system is equipped with protections to safeguard against anomalous situations affecting either the pressure
or voltage circuits.
Notifications
The unit is equipped, in addition to the signals and instruments installed on the electrical panel, with indicator lights
on the inside. To access them, it may be necessary to remove one or more covering panels. For further information,
refer to the wiring diagram and to the documentation attached to this manual.
ATTENTION: Operating the equipment with the panel removed should only be performed by
authorized/qualified personnel. Observe all safety precautions and use the necessary PPE. At
the end of such operation, always carefully replace all panels removed.
ATTENTION: All work requiring access to the compressor compartment and machine display
can be done with power on and the right-hand compartment door open.
ATTENTION: DO NOT access the gas cooler zone by opening the fan panel with power on.
ATTENTION: DO NOT access the electrical enclosure with power on.
ATTENTION: DO NOT work on the inverter or the electronic components with power on.
