Safety Instructions

Each PSU complies with Safety Class 1 of IEC60950, EN60950, UL60950,
CAN/CSA-C22.2 No.60950, and AS/NZS60950; therefore a protective earth connection exists between the
mains outlet ground and the PSU case. To ensure the PBX chassis is safely grounded, it is essential that
the PSU case be securely fastened to the PBX chassis with the 4 screws provided with each PSU.
When installing or replacing PSU, basic safety precautions should always be followed to reduce the risk of
fire, electric shock and injury to persons, including the following:
1.
Never install or replace PSU during a lightning storm.
2.
Never install or replace PSU in wet locations.
3.
Never install or replace PSU unless at least 20 s has elapsed after the AC supply is disconnected.
