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:
