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 a 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 a PSU during a lightning storm.

2.Never install or replace a PSU in wet locations.
