User manual ML Series 350-1000 VA UPS 1.0 (GB)

1  -  INTRODUCTION

2  -  INSTALLATION   

1.1 Introduction

  

The GE (General Electric) Digital Energy™ ML Series UPS, an uninterruptible power supply, protects  your 

equipment from all forms of power interference, including complete power failures.  

1.2 Safety Rules

CAUTION:

• 

  RISK OF ELECTRICAL SHOCK. 

The UPS contains batteries. The  appliance 

outlets may be electrically live, even when the UPS is disconnected from the  mains.  

The UPS contains potentially hazardous voltages. Do not open the UPS, there are no  

• 

user serviceable parts inside.  

Apart from battery replacement on the ML 350/500/700 models, all maintenance 

• 

and  service work should be performed by qualified service personnel.  
Always isolate the UPS from the mains during battery replacement.   

• 

1.3  Transport / Storage

No liability can be accepted for any transport damage when the equipment is shipped in non-

• 

original packaging.

Before storing, charge the batteries for at least 24 hours.

• 

Store the UPS in a dry location, storage temperature must be within -20 +45 °C. If the unit is 

• 

stored 

for a period exceeding 3 months, optimal battery lifetime is obtained if the storage  temperature 

does not exceed 25°C. Be sure that the UPS is switched off, and that no cable is  connected to the 

interface port.

If the unit is stored for a period exceeding 3 months, the batteries must be recharged  periodically. 

• 

Connect the unit to a wall outlet for a period of approx. 48 hours, minimum every 3  months.   

The shipping box contains a Digital Energy™ ML Series UPS, a power cord, a computer interface  cable, a 

CD ROM and this manual. After unpacking, inspect the UPS for damage. If you find any damage  please 

immediately notify the carrier and place of purchase.  

IMPORTANT:  

Before making any connection and switching on the Digital Energy™ ML Series UPS, please check the  

following conditions:  

your mains supply is 220 - 240 Volts and 50 Hz, and  

• 

the total power demand of the connected equipment does not exceed the rated output power of  

• 

the UPS (indicated on the rear panel).  

2.1 Installation Rules

  

The UPS is intended to be used in normal domestic and office situations.  

• 

Protect the UPS, according to the wiring rules, with a 16A D-type fuse.  

• 

The UPS must be powered from a single phase grounded wall outlet. Do not use extension  

• 

cords.  

Avoid locations that are excessively humid, near water, near heat sources or in direct 

• 

sunlight.  

The ambient temperature should not exceed 40

• 

°

C. Optimal battery lifetime is obtained if the  

ambient temperature does not exceed 30

°

C.  

It is important that ventilation air can move freely around and through the unit. Do not block 

• 

the  air vents.  

Do not plug appliances such as electric heaters, toasters and vacuum cleaners into the UPS.

• 

The UPS output can be used only for electronic loads such as computers and  

• 

telecommunications equipment.  

Be careful when connecting laser printers: be sure that the demanded power does not 

• 

exceed  the capacity of the UPS.
