lation Category II (transient voltage 2500V) and Meas-
urement Category II (control output, transient voltage
2500V). Reinforced insulation (Modbus or control out-
put or feedback resistance to power: 300V and Modbus
or feedback resistance to control output: 250V) is main-
tained. Prior to installation, check that the insulation
class of this unit satisfies the system requirements.
• The equipment must be mounted inside a suitable fire
enclosure.
• Altitude up to 2000 meters.
