Input and Output Connections
WARNING Only a qualified electrician should make the hardwired connections.
NOTE 5.5 kVA, 30A PowerTrust UPS products that are sold in Europe are
shipped without a line cord. It is the responsibility of the customer to get the
correct power cord for the particular country and electrical code, and to have
the power cord wired to the UPS input terminals.
5.5 kVA, 40A PowerTrust UPS products are equipped with two cords, one
with an IEC 309 receptacle for output power and one with an IEC 309 plug
for AC input power.
This section describes the hardwired input and output connections to the PowerTrust UPS.
In the worldwide version, the connections are made to the terminal block located behind
the access panels at the rear of the Service Bypass Unit (see Figure 3-10). The Worldwide
version is shipped without a line cord and without the L6-30R output receptacle; input and
output wiring connections must be hardwired. The North American version is prewired at
the factory with an input line cord terminated with an 6-50P plug and an L6-30R output
receptacle; no hardwiring is required.
CAUTION
It is recommended that you do not place intervening power conditioning
equipment between the PowerTrust UPS and the AC mains power source.
Such power conditioning equipment might interact with the PowerTrust UPS
or the connected load, causing faulty operation. If you must use power
conditioning equipment between the PowerTrust UPS and the AC mains
power source, the output of the nonferro-resonant power conditioning
equipment should be capable of supporting 3% voltage regulation for an
additional dynamic input current surge to the PowerTrust UPS of four times
the PowerTrust's operating input current rating. When in doubt, consult a
qualified site-preparation expert.
Wire Gauge Requirements
Always use the following wire gauge guidelines when making input or output connections
to the mains input and output terminal blocks.

Input: (L1 IN, L2/N IN): minimum 8 AWG (6 mm
2
) stranded copper wire
Ground: minimum 8 AWG (6 mm
2
) stranded copper wire
• Output Wiring:
The output terminals can accommodate stranded copper wire with a range of 14 AWG
to 4 AWG (2.5 mm
2
- 16 mm
