AC Power Requirements

The Strata CTX670 requires a single-phase, 50/60 cycles power source of 120, 208, or 240VAC, on a dedicated 20 ampere circuit breaker. 208VAC or 240VAC is required for six or seven cabinet systems.

The CTX670 power supply, BPSU672, automatically detects and adjusts for the type of AC voltage (120/208/240) to which it is connected.

Toshiba recommends that a dedicated AC service panel be used for the CTX670. AC outlets must be dedicated to CTX670 use, fused, and grounded. Equipment unrelated to the CTX670 must not be connected to the circuit or service panel dedicated to the CTX670.

Note It may not always be possible to power a complete CTX670 from a single circuit breaker panel. For example, in the case where a cabinet is remotely located.

To avoid accidental turn-off, do not configure the outlet serving the CTX670 with an On/Off switch. AC outlets serving the cabinets must be close enough so that the power cord from the cabinet power supply or power strip can reach the outlet (these power cords are nine ft.).

AC wall outlets for the CTX670 must be on dedicated 20amp breakers. AC outlets must meet National Electrical codes specifications: NEMA 5-20R for 120VAC or NEMA 6-20R for 208VAC/240VAC.

AC power cabling requirements vary, depending on: The method of cabinet installation (floor or wall mount), AC power source voltage (120VAC, 208VAC or 240VAC) and the number of cabinets. Requirements for distribution of AC power within the cabinets of the CTX670 are as described in Cabinet AC Power Distribution section.
