DK424i Installation
Step 4: Install AC Power Components
7-22
Strata DK I&M 6/00
Cabinet AC Power Considerations
The Strata DK424i power supply works with either 120VAC, 208VAC or 240VAC. The first
release of Strata DK424i only requires 120VAC (up to three cabinets if one AC cord is allowed or
five cabinets if two AC cords are allowed – see below).
In the future, the system will support more than five cabinets. In the case where system has more
then five cabinets, 208VAC or 240AVC is required for the primary AC power source. 208VAC or
240VAC can always be optionally used for systems with five or less cabinets for future growth or,
if the electrical code requires.
To determine AC power requirements, it is necessary to check local electrical code requirements
for 120VAC, 208VAC or 240VAC primary power. Some electrical codes stipulate that:
♦
208VAC or 240VAC is required for telephones systems
♦
Only one electrical cord can connect to the telephone system.
♦
Only two electrical cords can connect to the telephone system.
♦
No electrical cord can connect to the telephone system – must use conduit wiring installed by
a certified electrician (example: when system is floor mounted).

Primary AC power components required for Wall Mounted systems.
Important!
The plugs and wall receptacles required by the local electrical code might differ for
208VAC and 240VAC. Thus in some areas of the U.S., the plug used on the Toshiba
240VAC power strip and 240VAC power supply cord (NEMA code 6-20P) can not
be used for 208VAC installations. In this case, when using 208VAC, the AC plugs on
the BPSB240 power strip cord that connects directly to the 208VAC wall outlet must
be changed by a certified electrician per the local electrical code.

One dedicated, isolated, 20 amp. AC circuit breaker with dual outlets is required.
●
N/A= If the system contains more than three cabinets and if the local code allows only one AC cord, the system requires
a BCCB120 conduit box wired by a certified electrician when using 120VAC as primary power. Otherwise, 208VAC or
240VAC should be used as the primary power source (see cabinet power options listed below).
