LVD Installation Instructions
For more information about LVD, see 73/23/EEC and 93/68/EEC, published by the European
Economic Community (EEC).
Environmental Conditions
Pollution Degree
APEX615n Controller/Drives are designed for pollution degree 2.
Installation Category
APEX615n Controller/Drives are designed for installation category II.
Electrical
Connecting and Disconnecting Power Mains
The APEX615n Controller/Drive's protective earth connection is provided through its power
mains connector. You must reliably earth the APEX615n Controller/Drive's protective earth
connection.
Attach or remove the APEX615n Controller/Drive's power plug only while input power is
OFF.
Using an Isolation Transformer
The APEX615n Controller/Drive's mains voltage is limited to 240 VAC nominal. If your
mains voltage is higher, use an isolation transformer located between the power mains and the
APEX615n Controller/Drive. Your isolation transformer should be insulated to ~2300V rms.
Do not interrupt the protective earth conductor between the source mains and the isolation
transformer's secondary. The core of the isolation transformer and the drive's protective
conductor terminal must both be connected to the main's protective earth conductor.
CAUTION
Do not use an autotransformer.
