measured, it may be necessary that the power installation to the unit includes a transient limiting device.
Mains Filtration
If there is risk of power spikes or breaks, it is recommended that an Uninterruptable Power Supply (UPS)
is used to provide continued power and mains filtration. This should be rated according to the
HygroGen2 power specifications (see Appendix B3 ) and the time required to run/shut down during
power outage.
Conductive Pollution
The unit is rated Pollution Degree 2 and must not be operated in environments where conductive
pollutants (for example, carbon) may enter the unit. This includes excessive moisture ingress.
