Mitel SX-2000 - Manual (Page 239)

Specifications
50003510 Revision A 225
Electrical Characteristics
All power is derived from either a commercial ac source or an uninterruptible power supply
(UPS). All reserve power in the peripheral cabinet can have its own standard reserve power
in the base of the SX-200 system or can also be supported by an additional UPS. The UPS
assembly is not manufactured by Mitel Networks.
Power and Grounding
The system requires a single-phase, 115 Vac, 15 A circuit. A separate ground wire (size 6
AWG) must be installed between the equipment cabinets and the building ground. The ground
wire should be a separate ground wire from the hydro.
In addition to proper grounding, an AC surge suppressor is recommended between the SX-200
system and the 115 Vac outlet for each cabinet. This will protect the equipment from power
surges.
All trunks and off-premises extensions should be protected against lightning by gas tubes.
