Connecting
5.2 Connecting the 100 - 240 V AC Power Supply
SIMATIC HMI IPC677C
Operating Instructions, 04/2013, A5E02722710-04
47
Note
The power supply contains an active PFC (Power Factor Correction) circuit to conform to the
EMC guidelines.
Uninterruptible AC power systems (UPS) must supply a sinusoidal output voltage in the
normal and buffered mode when used with SIMATIC PCs with an active PFC.
UPS characteristics are described and classified in the standards EN 50091-3 and IEC
62040-3. Devices with sinusoidal output voltage in the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
Localized information
For countries other than the USA and Canada:
230 V supply voltage
This device is equipped with a safety-tested power supply cord which may only be
connected to a grounded safety power outlet. If you choose not to use this cable, you must
use a flexible cable of the following type: Min 18 AWG conductor cross-section and 15-A /
250-V shockproof connector. The cable set must be compliant with the safety regulations
and stipulated IDs of the country where the system is to be installed.
For the USA and Canada:
For the United States and Canada, a CSA or UL-listed power supply cord must be used.
The connector must be compliant with NEMA 5-15.
120 V supply voltage
A flexible cable with UL approval and with CSA label which has the following features is to
be used: Type SJT with three leads, min. 18 AWG conductor cross-section, max. 4.5 m in
length and parallel ground contact connector 15 A, min. 125 V.
240 V supply voltage
A flexible cable with UL approval and with CSA label which has the following features is to
be used: Type SJT with three conductors, min. 18 AWG conductor cross-section, max.
length 4.5 m, and tandem grounded connector 15 A, min. 250 V.
