Notes:

1.3- or 4-wire provided source.

2.Cables not provided by APC.

3.Recommended input over-current protection (MIB) based on an 80% rated device.

4.All AC cables must be AC 3- or 4-wire 3-phase.

5.Keep UPS input, output and control cables in separate conduits.

6.Installation must comply with all applicable national and local codes.

NOTICE!

Over-current protection and UPS input AC disconnect means must be provided.

See the “Technical Specifications” section in this Installation Guide for recommended UPS input and output over-current protection.

CAUTION!

UPS systems can be connected as 3-phase, a 3-wire plus ground, provided that the load is not connected to the neutral conductor.

NOTICE!

Only authorized electricians may install the UPS and all applicable codes must be observed.

NOTICE!

Always keep AC, DC and communication cables separated.

NOTICE!

The grounding electrode conductor (Protective Earth - PE) must be the same size (ampacity) as the UPS input circuit conductors. Conduit is not an acceptable grounding electrode conductor - see National Electrical Code Section 250-91(a).

NOTICE!

The unit is wired from the factory as a separately derived system. Output neutral is bonded to equipment ground through main bonding jumper inside the UPS. See National Electrical Code Article 250-5(d) and 250-26 for correct installation grounding.

NOTICE!

The maintenance bypass switch must be a 4-pole device switching all three phases and neutral. If you are using a 3-pole device, contact APC Technical Support for instructions on how to convert the unit to a not-separately derived system.
