Page 15: Installation Guide
4.1.3 Overvoltage protection SKOV A/S equipment are protected for high level of surge transient, but in some cases, specially in areas with frequent lightning strikes and power outage, additional protection is necessary. To reduce the risk of damaging the electronic equipment by large surge overvoltage, it is therefore recommended, always to install Surge Pro- tection Devices (SPD) in the mains supply. -
