Safety Precautions
This manual is about installation and operation of MUST400 modular UPS (Hereinafter referred as UPS).
Please carefully read this manual prior to installation.
The UPS must be debugged and maintained by an engineer commissioned by the manufacturer or the
agent. therwise, human safety may be endangered and the damage of UPS shall not belong to the
warranty scope.
APPLICABLE STANDARDS
This product complies with 2006/95/EC- CE 73/23 & 93/68 (low voltage safety) and 89/336 – 2004/108/EC
(EMC) , and EMC standards of Australia and New Zealand (C-Tick) , and the following UPS product
standards:
*IEC62040-1-1-General and safety requirements for use in operator access area
*IEC/EN62040-2 EMC requirements CLASS C3
*IEC62040-3 Performance requirements and test methods
WARNING- High earth leakage current
Earth connection is critical before connecting the input supply (include both utility supply and battery). This
equipment must be earthed in accordance with local electrical authority codes of practice.
Earth leakage current exceeds 3.5 mA and is less than 1000 mA.
Transient and steady-state earth leakage currents, which may occur when starting the equipment, should
be taken into account when selecting instantaneous RCCB or RCD devices.
Residual Current Circuit Breakers ( RCCBs) must be selected insensitive to DC unidirectional pulses
( class A ) and transient current pulses ( RCCBs).
Note it that the earth leakage currents of the load will also flow across RCCB or RCD.
Components that can be maintained by user
All the equipment maintenance and servicing procedures involving internal access need special tools and
should be carried out only by trained personnel. The components that can only be accessed by opening
the protective cover with tools cannot be maintained by user.
This UPS full complies with “IEC62040-1-1-General and safety requirements for use in operator access
area. UPS dangerous voltages are present within the battery box. However, the risk of contact with these
high voltages is minimized for non-service personnel. Since the component with dangerous voltage can
only be touched by opening the protective cover with a tool, the possibility of touching high voltage
component is minimized. No risk exists to any personnel when operating the equipment in the normal
manner, following the recommended operating procedures in this manual.
Battery Voltage Higher Than 400Vdc
All the battery maintenance and servicing procedures involving internal access need special tools or keys
and should be carried out only by trained personnel.
SPECIAL CARE SH ULD BE TAKEN WHEN W RKING WITH THE BATTERIES ASS CIATED WITH
THIS EQUIPMENT. WHEN C NNECTED T GETHER, THE BATTERY TERMINAL V LTAGE WILL
EXCEED 400Vdc AND IS P TENTIALLY LETHAL.
Battery manufacturers supply details of the necessary precautions to be observed when working on, or in
the vicinity of, a large bank of battery cells. These precautions should be followed implicitly at all times.
Particular attention should be paid to the recommendations concerning local environmental conditions and
the provision of protective clothing, first aid and fire-fighting facilities.

Chapter 1 Installation
This chapter introduces the installation of RM series UPS (hereby referred to as UPS), including
initial checking, sitting, positioning, cabling and installation drawings.
1.1 Introduction
This chapter introduces the relevant requirements for positioning and cabling of the UPS.
As each site has its requirements, this chapter provides step-by-step installation instructions, which
acts as a guide to the general procedures and practices that should be observed by the installing
engineer.
Warning-Installation can only be done by authorized engineers
1. Do not apply electrical power to the UPS equipment before the approval of commissioning
engineer.
2. The UPS should be installed by a qualified engineer in accordance with the information contained
in this chapter.
Note: 3-Phase 4-Wire Input Power is required
The standard UPS can be connected to TN, TT and IT AC distribution system (IEC60364-3) of
3-phase 5-wire
WARNING: battery hazards
SPECIAL CARE SH ULD BE TAKEN WHEN W RKING WITH THE BATTERIES ASS CIATED
WITH THIS EQUIPMENT. When connecting the battery, the battery terminal voltage will exceed
400Vdc and is potentially lethal.
 Eye protection should be worn to prevent injury from accidental electrical arcs.
 Remove rings, watches and all metal objects.
 nly use tools with insulated handles.
 Wear rubber gloves.
 If a battery leaks electrolyte, or is otherwise physically damaged, it must be replaced, stored in a
container resistant to sulfuric acid and disposed of in accordance with local regulations.
 If electrolyte comes into contact with the skin, the affected area should be washed immediately
with water.
1.2 Initial Checking
Perform the following checking operations prior to the UPS installation.
1. Visually examine if there is any damage inside and outside the UPS rack and battery equipment
due to the transportation. Report any such damage to the shipper immediately.
2. Verify the product label and confirm the correctness of the equipment. The equipment label is
attached on the back of front door. The UPS model, capacity and main parameters are marked on
the label.

1.3 Positioning
1.3.1 Distribution Room
The UPS is designed for indoor installation, which shall be located in a clean environment with
adequate ventilation to keep the environmental temperature within the required specification. The UPS
uses forced convection cooling by internal fans. Cooling air enters the module through ventilation grills
located at the front part of the cabinet and exhausted through grills located in the rear part of the cabinet.
Please do not block the ventilation holes.
If necessary, a system of extractor fans should be installed to aid cooling-air flow. An air filter should
be used when the UPS is to operate in a dirty environment and should be regularly cleaned to maintain
airflow.
Note: The UPS should be installed on a cement surface or other surface that is not
combustible
1.3.2 Battery Room
The battery will generate some amount of hydrogen and oxygen at the end of charging, so the
fresh air volume of the battery installation environment must meet EN50272-2001 requirements. The
ambient temperature of the battery must be stable. Ambient temperature is a major factor in determining
the battery capacity and life. The nominal operating temperature of battery is 20°C. perating above this
temperature will reduce the battery life, and operation below this temperature will reduce the battery
capacity. If the average operating temperature of battery is increased from 20ºC to 30ºC, then the
service life of the battery will be reduced by 50%. If the operating temperature of the battery is above
40ºC, then the battery service life will be decreased in exponent rate. In a normal installation, the battery
temperature is maintained between 15°C and 25°C. Keep batteries away from heat sources or air
outlets.
If external batteries are to be used, a battery protection device (a DC circuit breaker) must be
mounted as close as possible to the batteries, and the connecting cables should be as short as possible.
1.3.3 Storing
If the equipment is not installed immediately, it must be stored in a room so as to protect it against
excessive humidity and heat sources. The battery needs to be stored in dry and cool place with good
ventilation. The most suitable storage temperature is 20 ºC to 25ºC.
1.4 Disassembly, Initial Checking and Positioning
Check the packaging first upon the arrival of product to see if there is any damage; open the
packaging to check the equipment; report any such damage to the shipper immediately.
1.4.1 System Packaging:
pen the wooden case first, the open method is shown in fig 1-1:
