Checking the installation prerequisites
Before you install a main unit or expansion unit, perform the following tasks:
• Determine the location for the BCM50 units, telephones, and other equipment based on space
and electrical requirements.
• Order the required trunks from the central office.
• Ensure that you have all the equipment and supplies you need to install the system.
For information about BCM50 installation prerequisites:
• Environmental requirements on page 77
• Electrical requirements on page 77
• Site telephony wiring requirements on page 78
• System equipment, supplies, and tools on page 79
Environmental requirements
Ensure you meet the installation environmental requirements. The installation area must be:
• a minimum of 4 m (13 ft.) from equipment such as photocopiers, electrical motors, and other
equipment that produces electromagnetic, radio frequency, and electrostatic interference
• within 1.5 m (5 ft.) of a three-wire grounded electrical outlet
• clean, dry, well ventilated, and free of traffic and excess dust
• within the temperature range of 5°C and 50°C (40°F and 120°F)
• from 20% to 80% non condensing relative humidity
• structurally strong and with enough space to support the BCM50 units
• a minimum of 46 cm (18 in.) from the floor
Electrical requirements
Ensure you meet the following electrical requirements:
• Power must be supplied from a non switched, unobstructed outlet within 1.5 m (5 ft.) of the
BCM50 units.
• The supplied power must be a dedicated 110 V to 120 V AC nominal (or 220 V to 240 V AC
nominal), 50 to 60 Hz, 15 A minimum service with a third-wire safety ground. The third-wire
safety ground provides shock protection and prevents electromagnetic interference.
Note: The installation area must be of sufficient height from the floor to prevent water
damage.
