INSTALLATION AT HIGH ALTITUDE
There is a risk for overvoltage. Isolation between components and critical parts could be insufficient and may not comply with
PELV requirements.
Use external protective devices or galvanic isolation. For installations above 2000 m (6500 ft) altitude, contact Danfoss re-
garding protective extra low voltage (PELV) compliance.
