AC Power Requirements
UL Requirement: „
The ADIX-VS system must be connected to an outlet with a protective earth
ground connection.
„
The outlet shall be installed near the equipment and shall be easily accessible.
Clean power and proper grounding for the VS-KSU Control Module is required to maintain problem-
free operation. The customer must provide a dedicated single-phase, 120 volt AC, 60Hz grounded
outlet. A conventional duplex NEMA 5-15R electrical outlet is required. A 15-ampere breaker is
required for the outlet to support the ADIX-VS system. The ADIX-VS System draws a maximum of
2 Amperes.
The AC circuit must conform to National Electrical Code (NEC) standards and be capable of
providing noise-free power to the power supply unit. Line noise such as electromagnetic interference
(EMI) may cause erratic system operation.
)
To protect the ADIX-VS System:
ƒ
If AC voltage fluctuation is greater than the allowable range defined on page 32 install a
computer-grade AC line voltage regulator as illustrated in Figure 2, Example 1.
ƒ
Install a noise filter on the AC power input line to prevent noise interference through the AC line as
illustrated below.
ƒ
Install battery backup to maintain system power in the event of a power outage.
ƒ
Do not place radio frequency, electromagnetic or inductive devices near the ADIX-VS.
ƒ
Use a dedicated 15-ampere AC circuit with an isolated communications ground as defined in EIA/
TIA 607, as illustrated in Figure 2. Do not use AC outlets that are shared with air conditioners or
equipment such as a copy machine.
Use a dedicated electric circuit with a dedicated communications ground.
