Note
Operation with uninterruptible power supply
An uninterruptible AC power supply (UPS) must be used when this device is operated with a
PFC (Power Factor Correction) circuit that supplies a sinusoidal output voltage in normal and
buffer mode.
UPS characteristics are described and classified in the standards EN 50091-3 or
IEC 62040-3. Devices with sinusoidal output voltage in the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
Note
The power supply of the device contains a PFC (Power Factor Correction) circuit to conform
to the EMC directive.
Country-specific information on supply voltage
230 V supply voltage outside of the USA and Canada
This device is equipped with a safety-tested power cord which may only be connected to a
grounded shockproof power outlet. If you do not use the power supply cable, use a flexible
cable with the following features:
● Conductor cross- section ≥ 0.82 mm
2
● Grounded safety plug 15 A, 250 V
The power supply cable must conform to the safety regulations of the country in which the
devices are installed and bear the marks required in each case.
230 V supply voltage for the USA and Canada
Use a CSA or UL-listed power supply cable for operation in the United States and Canada.
The connector must be compliant with NEMA 5-15.
120 V supply voltage
Use a flexible cable with UL approval and CSA marking as well as the following features:
● Type SJT with three conductors
● Conductor cross- section ≥ 18 AWG
● Cable length ≤ 4.5 m
● Parallel grounding-type plug 15 A, ≥ 125 V
240 V supply voltage
Use a flexible cable with UL approval and CSA marking as well as the following features:
● Type SJT with three conductors
● Conductor cross- section ≥ 18 AWG
● Cable length ≤ 4.5 m
● Tandem grounding-type plug 15 A, ≥ 250 V
