Connecting
5
Connect a jumper wire (the same wire gauge as the other AC wires) between the termi-
nals labeled “L2/L” and “L2/N”.
6
Connect the third AC hot wire, typically blue, to the input terminal labeled “L3/N”.
Single-phase operation
Single-phase input power requirements for SYNRAD’s PS-96 DC power supply are 208–264
VAC, 1Ø (single phase), 20 A maximum, 47–63 Hz. Table 1-5 provides recommendations for
single-phase input wiring and fusing.
Table 1-5 Single-phase AC electrical recommendations
Parameter Recommendation
Input voltage 208–264 VAC, 1Ø
Input current, max. 20 Amperes
Wire gauge 10 AWG
Fuse/circuit breaker 30 Amps
There are two possible circuit congurations for single-phase connections: (1) one circuit
where the voltage between hot conductors measures 208–264 VAC (recommended), or (2)
an alternate case using two individual circuits where the voltage between the hot and neutral
conductors from each individual circuit measures 120–264 VAC. To connect single-phase AC
input power to the PS-96 power supply, refer back to Figure 1-14 and perform the following
steps:
Note: Because AC input connections and requirements vary from facility to facility, custom-
ers must provide the AC power cable or wiring.
One single-phase circuit (208–264 VAC)
1
Follow your facility’s Lockout/Tagout procedures and verify that input AC power to the
DC power supply is physically locked out or disconnected.
2
Connect the safety ground (earth) wire, typically green, to the input terminal labeled
“GND”.
3
Connect one AC hot wire, typically black, to the input terminal labeled “L1/L”.
All AC input wiring and fusing to the DC power supply must be
sized and connected in accordance with applicable local, state, and
national requirements.
Local, state, and national code requirements (like NEC, CSA, and
IEC 60364) supersede any recommendations provided in this manual.
