User's Manual

• Power supplies — The control unit has an internal power supply unit. Each external
expansion module is supplied with an external power supply unit. Additional power supply
units may also be required for IP phones and some phone add-ons.
• Power cords — Depending on the locale, different power cords need to be ordered for
each control unit, external expansion module, and any phones or devices using external
power supply units.
• Mounting kits — The control unit can be used free-standing, with external expansion
modules stacked above it. With optional rack mounting kits, the control unit and external
expansion modules can also be rack mounted. Alternatively, with an optional wall
mounting kit the control unit can be wall mounted. However, the control unit cannot
support any external expansion modules when wall mounted.
• Surge protectors and barrier boxes — Where the installation includes extensions in
other buildings, additional protective equipment is required. This equipment may also be
required in areas where the lightning risk is high.
