1 General Description

1.1 Introduction

This chapter describes the purpose, principle of operation and user controls of the Hinet series on-line Uninterruptible

Power Supply (UPS).

The Hinet series UPS is connected between a critical load, such as a computer, and the mains. Its purpose is to provide

the load with regulated power under all rated load and input supply conditions; i.e. the power provided by the UPS will

be protected from any voltage or frequency variations on the input power supply, or variations in the supply due to

electrical noise, and will continue during periods of input power supply failure. A battery provides a standby power

source for the UPS when the input power supply fails.

1.2 Equipment construction

The equipment is constructed around a steel frame with removable panels. The door can be open to give easy access to

the input, bypass, output, reserve line circuit breakers and battery C.B. fused switch, while protecting them from

accidental operation.

An LCD control panel on the front of the cabinet permits the operator to monitor the UPS.

The cabinet houses both the power components and the batteries.

It is carried on four wheels. Jacking feet help to support the UPS, and also prevent it from moving once it has been

wheeled into its final position. These feet are also used to secure the equipment to its shipping pallet during transit.

Cooling is by internal fan. Air is drawn in from beneath the UPS and exhausted through ventilation grills of the front

panel. These areas must be kept free of anything that may avoid the air flow into and out of the unit.

1.2.1 Principle of operation

Normal operation

During normal operation, i.e. when the UPS input supply is present and within specification, both the converter and

inverter sections are active and the automatic by-pass is turned on to connect the inverter output to the critical load

terminals. The battery fuse-holder switch is also closed and the battery is therefore permanently float charged at the d.c.

terminals voltage level.

Mains Failure

If the mains has a failure or is out of tolerance the converter will be supplied from the battery, while the inverter will

continue to operate for a period of time which depends on the load and the capacity of the battery. If the mains supply

has not returned within this time, the inverter will go off automatically and an alarm condition will appear on the UPS

operator control panel.

Critical load will not be interrupted in the event of a drop or return of the AC power mains.

Return of power mains

When the mains returns within the required tolerance, the converter will be automatically supplied from mains,

supplying power to the inverter and recharging the battery at the same time. There will be no interruption of the critical

load.

UPS fault

In the event of an inverter failure, the automatic by-pass will automatically transfer the load onto the mains with no

interruption. In such an event, request qualified technical assistance.

The load will be transferred with no interruption if the inverter is synchronised with the mains; if this is not the case,

there will be an interruption of some milliseconds.

The intervention of the automatic by-pass line is shown on the front panel by the yellow led on.

WARNING

CAUTION: When the load is being supplied from the bypass line through the automatic bypass, it is connected

directly to the mains supply and is therefore no longer protected against main faults.

Maintenance Bypass

A second bypass circuit contained in the UPS cabinet, identified as the ‘Maintenance Bypass’ line is included to enable

the reserve supply to be made available to the load while facilitating a safe working environment for carrying out

scheduled UPS system maintenance or trouble shooting. The circuit is manually selected by the Manual Bypass Switch

(3) which can be padlocked in the OFF position.

WARNING

CAUTION: If an automatic circuit breaker device is not present in the input distribution panel, there remains a

dangerous voltage at the output terminals and also on the input terminals of the UPS module that is switched off.

Note: The load is not protected from main aberrations when operating on the maintenance bypass mode .

1.2.2 UPS Power Configuration

Figure 1-2 illustrates the Hinet UPS in what is known as the “Common Bypass” configuration. In the “Split Bypass”

configuration the static bypass line is connected by a separate power switch to a dedicated `bypass' power source that

also feeds the maintenance bypass line. Where a separate power source is not available the Reserve and Converter input

supply connections would be linked together.

With the exception of the maintenance bypass switch (3), all the isolators shown must be closed during normal UPS

operation.

1.2.3 Battery fuses switch

The battery is connected to the d.c. bus through a battery fuses switch (5) fitted inside the UPS cabinet.

2 Installation (Mechanical)

2.1 Preliminary Checks

Before installing the UPS hardware the following preliminary checks must be carried out:

1. Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification, paying

particular attention to the ambient temperature and air exchange system.

2.1.1 Material admittance

1. Remove any packaging debris, then visually examine the UPS and battery equipment for transit damage, both

internally and externally. Report any such damage to the shipper immediately.

2. Afterwards ascertain that the material supplied is as that reported on the freight bill.

2.1.2 Identification

The equipment supplied is provided with an adhesive identification label placed on the UPS rear panel reporting type of

UPS model and power.

The cases utilised to transport the equipment must be unpacked as specified by the procedure stated below.

2.1.3 Packing material removal

During this operation observe the indications (FRAGILE, UP) printed on the case to avoid damaging the UPS Hinet.

To remove the packing material proceed in the following manner:

- Place the equipment on the floor as instructed on the outer case (UP, DOWN).

- Use the extractor to remove the top of the crate .

- Remove the extruded elements utilised as packing protection.

- Use the extractor to remove all lateral sides of the crate

- Slide the forks of the lift truck under the UPS and after having lifted it a few centimeters from the floor, back up and

lay it down.

Hinet is provided with wheels to easily move it around.

- Do not throw away the packing material it might be used again to repack the equipment if having to send it back or to

send it to maintenance centres or for removal purposes.

- Check that the equipment has not been damaged. If otherwise immediately contact the Sales Representative.

2.1.4 Moving the cabinets

WARNING

Ensure that any lifting equipment used for moving the UPS cabinet has sufficient lifting capacity.

ENSURE THAT THE UPS WEIGHT IS WITHIN THE DESIGNATED WEIGHT LOADING (KG) OF ANY

HANDLING EQUIPMENT. SEE THE UPS SPECIFICATION FOR WEIGHT DETAILS.

The UPS can be lifted using a fork lift. Take care when using either method not to damage the UPS castors located on

the bottom of the unit.

2.1.5 Placing it in the operative position

The UPS cabinets are fitted with castors on the base to allow ease of movement and positioning.

WARNING

Castors are of sufficient strength for movement across even surfaces only. Castor failure could occur if subjected to

shock loading

When the equipment has been finally positioned ensure the adjustable feet are set so that the UPS will remain stationary

and stable

The place chosen must guarantee:

- easy connection;

Hinet UPS User Manual

Page 6 (12/01)

- enough space to easily work on UPS;

- exchange of air sufficient enough to dispel heat produced by UPS;

- protection against atmospheric agents;

- protection against excessive humidity and very high heat sources;

- protection against dust;

- compliance with the current fire prevention norms.

- operative environment temperature within +20° C and +25° C. The batteries are at maximum efficiency in this

temperature range.

2.1.6 Clearances

Cooling air enters the module through ventilation grills located at the bottom of the cabinet and is exhausted through the

fan grills located on the front panel; you must therefore allow for a minimum gap of 170 mm behind the unit to allow

adequate air flow. Clearance around the front of the equipment should be sufficient to enable free passage of personnel

with the door fully opened.

2.1.7 Raised floor installation

If the equipment is to be located on a raised floor it must be mounted on a pedestal suitably designed to accept the

equipment point loading. Refer to the base view to design this pedestal.

3 Installation (Electrical)

The UPS requires «power» cabling once it has been mechanically installed. All «auxiliary» cables, whether screened or

not, should be run separate from the power cables in metal conduits or metal ducts which are electrically bonded to the

metalwork of the cabinets to which they are connected.

3.1 Power Cabling

WARNING

BEFORE CABLING-UP THE UPS, ENSURE THAT YOU ARE AWARE OF THE LOCATION AND OPERATION

OF THE EXTERNAL ISOLATORS THAT CONNECT THE UPS INPUT/BYPASS SUPPLY TO THE MAINS

DISTRIBUTION PANEL.

CHECK THAT THESE SUPPLIES ARE ELECTRICALLY ISOLATED, AND POST ANY NECESSARY WARNING

SIGNS TO PREVENT THEIR INADVERTENT OPERATION.

3.1.1 Power Cable connections

The terminal block is at the rear of the cabinet.

The bar near the terminals blocks can be used to fasten the cable to the UPS through cable clamps.

3.1.2 Safety earth

The safety earth bus-bar is located near the UPS output terminals. The safety earth cable must be connected to the earth

terminal and bonded to each cabinet in the system.

All cabinets and cable trunking must be earthed in accordance with local regulations.

WARNING

FAILURE TO FOLLOW ADEQUATE EARTHING PROCEDURES CAN RESULT IN ELECTRIC SHOCK

HAZARD TO PERSONNEL, OR THE RISK OF FIRE, SHOULD AN EARTH FAULT OCCUR.

BEFORE ANY OTHER CABLE CONNECTION THE PE SAFETY CONDUCTOR SHALL BE CONNECTED

3.1.3 Protective devices

Input supply protection:

All supplies to the UPS must be provided with three phase power breakers or fuses, a split bypass system will require

two devices. To avoid random tripping on start up due to initial inrush current, a circuit Breaker type C (or slower) is

recommended. Refer to the following table in order to choose site supply fuses, circuit breakers and power isolators

appropriate to the UPS current rating.

Protection against earth faults (RCD devices):

In the event of a differential (RCD) device being installed upstream of the input supply, one must take into account the

transient and steady state earth leakage currents that are produced during start-up of the UPS.

The presence of an RFI suppression filter inside the UPS, determines a residual earth current no greater than 500 mA.

Only RCD delayed device Type A must be used (suited to unidirectional current).
