In Finland, Norway, and Sweden, you must install the Branch Gateway in a restricted access location (RAL), due to unreliable earthing concerns. Only service personnel who have been instructed about the restricted access, and safety precautions can access RAL. Service personnel can access Branch Gateway using a tool, such as a lock and key, or other means of security.
Warning:
For installations in Finland, Norway, and Sweden, the AC powered Branch Gateway relies on two ground connections: the mains plug with an earth contact and a supplementary ground conductor.
