those described above, otherwise the Inverter may break or malfunction due to imperfect contact.
2. Never attach the front cover to the Inverter with the Digital Operator attached to the front cover. Imperfect
contact can result.
Always attach the front cover to the Inverter by itself first, and then attach the Digital Operator to the front
cover.
