INSTALLATION

Read Operation section to understand user controls and displayed messages before beginning.

Operate UPS in a clean, controlled environment with adequate airflow.

Exposure to excessive dirt or dust adversely affects UPS operation.

Internal fans cool the UPS. The unit intakes air at the front and exhausts it out the rear. Allow at least one foot of space around UPS for air circulation. Operate UPS within specified temperature and humidity limits.

Allow only authorized personnel to service UPS. Allow a minimum of 3 feet access on both sides for rigid conduit installations. Units that can be rolled forward for side service access require no side access in their normal position. Manual UPS operation and connection to UPS receptacles requires rear access.

3.5-6 kVA Connections

See the figure to the right for connection locations.

CAUTION: A qualified electrician must review and approve customer-supplied wiring, circuit breaker(s), power outlet, and intended loads. Ensure correct line, neutral, and ground connections, and that phase rotation is phase A leads phase B. See Site Planning Data and Table NEC Wire Specifications in the Appendix.

3.5- 6 kVA Liebert UPStation S™ systems include the UPS and the AC unit. The unit provides connection to both utility power and UPS output power through the use of a simple Maintenance Bypass Switch. See the

Operation section for instructions on Maintenance Bypass Switch use.

Input

The input power cord includes a NEMA L14-30 plug. The cord is six feet long and rated for 30 Amps. Customer supplied wiring must include an L14-30 receptacle and a 30 Amp circuit breaker.

Output

The POD contains the output receptacles.
