Installation

Siting considerations

Before unpacking and installing the unit, consider the following:

■

DO NOT expose the UPS to high temperatures, water ingress, flammable or corrosive gas, dust, direct sunlight or explosives.

■

Locate the UPS indoors on a level surface as close as possible to the equipment it will be powering to minimise cable voltage drops. Allow enough spare cable to move the UPS and access the rear and side panels during servicing.

■

Maintain a gap of at least 20 cm between the ventilation holes/slots at the front and rear of the unit, and walls or other equipment. When rack mounted in a cabinet, ensure there is adequate airflow.

■

For maximum battery life and improved product reliability ensure cool air is available at the front of the unit. As an approximation, battery life is halved for every 10K (10°C) rise in temperature.

■

Ensure the ambient temperature is in the range 0 to 40°C. If you need to operate the UPS above

40°C, derate the output by 2.4% per °C increase in temperature. The maximum operating temperature is 50°C.

Wiring considerations

To ensure a safe installation please follow these instructions and the local electrical code of the area or country in which you are installing the equipment:

■

If the UPS is to be supplied from a local transformer, ensure the transformer kVA rating is at least

50% greater than the UPS output kVA rating.

■

Use the cables provided to wire up the input and output. The cables are fitted with the appropriate female and male connectors for input and output respectively.

■

If using external batteries, you will be supplied with a separate battery box that includes a battery breaker, or you may be supplied with a set of battery leads and a breaker (50 A MCB single-pole).

Caution: As a minimum you must fit a 50 A single pole MCB in the battery line. However, you can use a double pole breaker if you prefer.

■

If supplying your own external battery, do not exceed 56 Ah. The use of higher capacity batteries is possible with additional charging capacity. Consult your distributor for details.

■

DO NOT connect inductive loads such as motors, fluorescent lamps and photocopiers to the UPS, as damage may occur.

■

Ensure the mains supply has over-current protection and a good ground.

■

When connecting a laser printer to the UPS, ensure the capacity of the UPS is equal to or greater than the highest power rating of the laser printer plus any other loads.

Operation from a generator

As a guide we recommend that the load capacity should be less than 30% of the generator capacity, and the generator rating should be 1.5 to 2 times the rating of the UPS, depending on the type of generator used.

Caution: Ensure that the neutral line from the generator is permanently connected to the mains neutral line. Do not use an MCB or any other type of switch in this line.

User Manual

Operation

Secure Power Ltd

Working modes

The UPS has four distinct modes of operation:

■

On-line mode

■

Bypass mode

■

Battery mode

■

ECO mode

Each operating mode is described below.

On-Line mode

This is the default mode of operation in which the load is supplied via the AC/DC converter and inverter when the a.c. input and load are within their normal ranges. In this mode the green inverter LED is on and the battery is trickle charged.

During fault conditions the UPS automatically switches to either bypass mode or battery mode without interruption to the load.

Bypass mode

In bypass mode the load is supplied directly from the a.c. input and the battery is charged. The UPS switches to bypass mode when any of the following conditions occur:

■

An output overload – the unit beeps twice every second, indicating that the load must be reduced to within its normal range as soon as possible. Once the overload is removed the inverter re-starts after a 5 minute delay. If the UPS is overloaded too many times in any one hour it will eventually remain in bypass mode.

■

The UPS is too hot – the UPS reverts to on-line mode as soon as the unit temperature returns to normal.

■

The UPS fails – a serious fault has occurred within the UPS that must be repaired.

■

The UPS is turned off.

In bypass mode the inverter LED is off and the amber bypass LED is on.

Battery mode

In battery mode the load is supplied from the battery via the DC/DC converter and inverter, the UPS beeps every 3 s, and the AC/DC converter and charger are turned off. The UPS switches to battery mode when there is no a.c. input or the a.c. input is outside its normal range. On the front panel the inverter and battery LEDs are on.

When the battery reaches a preset low limit, the system gives a low battery voltage alarm signal, the LCD provides a low battery alarm, and the UPS beeps every second. Eventually the UPS shuts down to prevent damage to the batteries.

When the a.c. mains is restored the inverter starts automatically and the UPS reverts to on-line mode.

ECO mode

If specified, your UPS may be set to operate in ECO mode instead of on-line mode. In ECO mode the load is supplied via the bypass circuit and not the AC/DC converter and inverter, allowing the UPS to work at higher efficiency. The battery is trickle charged in this mode. If the a.c. input is lost or goes beyond its normal range the UPS automatically switches to battery mode, however, the transfer speed is slower than on-line mode and may not be suitable for all applications.

Note: Do not use ECO mode when the mains is of poor quality.

Maintenance

SP200R series units use sealed lead acid, maintenance free batteries and require minimum maintenance in general. To keep the batteries fully charged and in good condition, ensure the UPS is plugged into the mains at all times. The UPS battery charger guards against over-charging and deep discharge.

Fan

At normal room ambient temperature the fans will operate continuously for 20,000 to 40,000 hours.

Increased ambient temperatures will shorten this lifetime.

Periodically ensure that there is air is blowing out of the rear of the unit.

Battery

For units with external batteries we recommend the use of sealed lead acid, maintenance free batteries.

Units with internal batteries are fitted with this same type of battery. Battery life depends on the ambient temperature and the number of discharge/charge cycles. Battery life is shortened with high ambient temperature and deep discharges.

To maximise the life of your batteries, maintain them as follows:

■

Maintain the ambient temperature in the range 15 to 25°C

■

Avoid discharge currents of less than 10% of full load current.

■

Do not operate the UPS in battery mode continuously for more than the specified autonomy (hold-up time).

■

Charge the battery for at least 12 hours every 3 months if it has not been used. If the ambient temperature is higher than 25°C, charge the battery every 2 months.

■

Maintain external batteries at least once a year.

If the backup time has significantly reduced, or a battery fault is displayed on the LCD screen contact your distributor to find out if the batteries need replacing.

WARNING

DON'T SHORT CIRCUIT THE BATTERY AS IT CAN CAUSE A FIRE.

DON’T OPEN THE BATTERY AS THE ELECTROLYTE INSIDE IS HARMFUL TO SKIN AND

EYES.

External battery change

Caution: We strongly recommend you switch off the whole UPS when you need to change an external battery group.

Visual check

Ensure there is adequate ventilation to maintain the UPS at the correct temperature.

UPS status check

Check the following:

■

Ensure there are no faults or alarms indicated.

■

If the UPS is working in bypass mode, investigate the cause.

■

If the UPS is working in battery mode, make sure it is normal, if not, investigate.

You can connect to a 9 pin D-type connector on the card or to a 16-way terminal block mounted internally on the card.

Note: If you want to connect to the Remote shutdown and the Operation indication or other N/C signals you will need to connect to the relay card using both connection methods described above.

User Manual

To use the 9 pin D-type connector:

1. On the UPS, plug your signal cable into the D-type connector and secure with the screw locks.

2. On the other end of the cable, wire the signals as required in your system (see the connection table on the previous page and the pin out information below).

D-type socket pin-outs looking at the socket on the UPS

To connect to the 16-way terminal block:

Note: There is limited space between the terminal block and the edge of the mounting slot. It is therefore advisable to use fine wire (0.5 mm

2

max.) to make it easier to bend and dress the wires out of the way.

1. Using a PH2 Phillips screwdriver, remove the two screws holding the relay card in place, and remove the card.

2. Feed your signal wires through the hole in the cover plate and wire to the appropriate terminals (see the connection table on the previous page).
