request of the Customer

on the customer's request — по просьбе [требованию\] клиента [заказчика\]

On the customer's request, the boat can be furnished with an anchor. — По просьбе клиента лодка может быть снабжена якорем.

request slip — бланк заявки

to be in great request — пользоваться большим спросом

as requested in your letter — как вы просили в вашем письме

he received the information he had requested — он получил информацию, которую запрашивал

услуга, ориентированная на заказчика
(ITIL Service Design)
ИТ-услуга, видимая заказчику. Обычно это услуги, поддерживающие бизнес-процессы заказчика и способствующие получению одного или нескольких конечных результатов. Все ориентированные на заказчика услуги, находящиеся в эксплуатации, включая готовые к развёртыванию, записываются в каталог услуг вместе информацией о результатах, ценах, способах заказа и контактной информацией. Также должны вестись записи о другой информации (например, взаимосвязи с поддеживающими услугами и другими КЕ) для внутреннего использования поставщиком ИТ-услуг.

customer-facing service
(ITIL Service Design)
An IT service that is visible to the customer. These are normally services that support the customer's business processes and facilitate one or more outcomes desired by the customer. All live customer-facing services, including those available for deployment, are recorded in the service catalogue along with customer-visible information about deliverables, prices, contact points, ordering and request processes. Other information such as relationships to supporting services and other CIs will also be recorded for internal use by the IT service provider.

to place a verbal purchase order and later send a confirming purchase order — сделать заказ устно и затем направить подтверждающий документ

to issue a purchase order — выписывать заказ на покупку

A qualified supplier must be identified before a purchase order is issued.

purchase order quantity — количество товара в заказе на покупку

to send the purchase order to the supplier — отправить поставщику заказ на покупку

Once a quote has been accepted, the customer will send the purchase order to the supplier.

If the supplier fills the order from its inventory, it turns the customer purchase order into a pick ticket, a packing list, and an invoice.

For example, a customer wanting to purchase a particular automobile that was not then in stock typically would sign a purchase order for the new car.

blanket purchase order — бланк заказа на покупку

параллельная система ИБП
-
[Интент]

Parallel Operation: The system shall have the option to install up to four (4) UPSs in parallel configuration for redundancy or capacity.
1. The parallel UPS system shall be of the same design, voltage, and frequency. UPS modules of different size ratings shall be permitted to be paralleled together for purposes of increased capacity or UPS module redundancy. The UPSs in the parallel configuration shall not be required to have the same load capacity rating.
2. Parallel Capacity: With N+0 system-level redundancy, up to 2MW of load can be supported by the system.
3. Parallel Redundancy: With N+1 system-level redundancy, up to 1.5MW of load can be supported by the system, and only the UPS being replaced must be isolated from the source (bypass operation is not required for the entire system during the UPS replacement procedure).
4. Output control: A load sharing circuit shall be incorporated into the parallel control circuits to ensure that under no-load conditions, no circulating current exists between modules. This feature also allows each UPS to share equal amounts of the total critical load bus. The output voltage, output frequency, output phase angle, and output impedance of each module shall operate in uniformity to ensure correct load sharing. This control function shall not require any additional footprint and shall be an integral function of each UPS. The static bypass switches shall be connected in parallel.
5. Parallel System Controls: To avoid single points of failure, the UPS system shall have no single dedicated control system designed to control the operation of the parallel UPS system. Control of and direction of parallel UPSs shall take place via a master/slave relationship, where the first UPS to receive logic power asserts itself as a master. In the event of a master failure, a slave UPS shall take the role of master and assume the responsibility of the previous master UPS. Regardless of which UPS is master or slave, user changes to the system status, such as request for bypass, can be done from any UPS connected to the bus and all UPS on the bus shall transfer in simultaneously.
6. Communication: Communication between modules shall be connected so that the removal of any single cable shall not jeopardize the integrity of the parallel communication system. Load sharing communications shall be galvanically isolated for purposes of fault tolerance between UPS modules. A UPS module's influence over load sharing shall be inhibited in any mode where the UPS inverter is not supporting its output bus. Transfers to and from bypass can be initiated from any online UPS in the system.
7. Display: Each UPS multi-color LCD touch screen user interface shall be capable of using an active touch screen mimic bus to show the quantity of UPS(s) connected to the critical bus, as well as the general status of each UPS, such as circuit breaker status information. Any touchscreen display shall support the configuration of the [entire parallel] system and shall provide event and alarm data for all UPSs in the parallel configuration. A Virtual Display Application shall be available for download to the customer’s computer and shalll support remote monitoring of a complete system with up to 4 UPSs in parallel.
8. Battery runtime: Each UPS must have its own battery solution. The battery solution for the entire system can be a combination of standard and third-party batteries, but each UPS must use only one battery solution – either standard or third-party batteries.
9. Switchgear: A custom switchgear option shall be required for parallel operation.
