CAUTION!
• Wiring must be performed by qualified professional personnel.
• Before wiring or making any electrical connection, ensure the power supplied to the input and output of the UPS is cut off
completely and the internal battery connectors are disconnected.
• When connecting the UPS to the utility AC power and bypass source, protective devices and 3-pole connectors must be
installed. The protective devices and 3-pole contactors must use approved components that meet safety certifications. The
thermo-magnetic circuit breakers should be IEC 60947-2 trip curve C (normal). Refer below for required protective devices:
25kVA UPS: 100A input circuit breaker required.
30kVA UPS: 125A input circuit breaker required.
50kVA UPS: 200A input circuit breaker required
60kVA UPS: 250A input circuit breaker required
80kVA UPS: 320A input circuit breaker required
100kVA UPS: 400A input circuit breaker required
• When connecting the critical loads to the UPS, a listed certified breaker must be installed between them. Refer to the below
for the required breakers:
25kVA UPS: 100A input circuit breaker required.
30kVA UPS: 125A input circuit breaker required.
50kVA UPS: 200A input circuit breaker required
60kVA UPS: 250A input circuit breaker required
80kVA UPS: 320A input circuit breaker required
100kVA UPS: 400A input circuit breaker required
• Check that the size, diameter, phase and polarity of each cable connecting to the UPS is correct. For the specifications of
input/output cables, refer to the table in section 3.10.1 Power Cables.
