Checking the installation prerequisites

Before you install a main unit or expansion unit, do the following:

•Determine the location for the BCM50 units, telephones, and other equipment based on spacing 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.

Refer to the following sections for information on BCM50 installation prerequisites:

•“Environmental requirements”

•“Electrical requirements”

•“Site telephony wiring requirements” on page 76

•“System equipment, supplies, and tools” on page 77

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, free of traffic and excess dust, dry, and well ventilated

•within the temperature ranges of 5°C and 50°C (40°F and 120°F)

•between 20% and 80% non-condensing relative humidity

•structurally strong enough and with enough space to support the BCM50 units

•a minimum of 46 cm (18 in.) from the floor

Note: The installation area must be of sufficient height from the floor to prevent water damage.

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), 50/60 Hz, 15 A minimum service with a third-wire safety ground. The third-wire safety ground provides shock protection and prevents electromagnetic interference.
