3 Safety
3.1 General safety instructions
Read and observe the user manual and safety instructions in this chapter before
taking any further action (transportation, storage, connection, startup, etc.).
Since the UPS equipment uses mains voltage and incorporates an appropriate
energy accumulator (high-capacity batteries) either on the inside or outside of
the device, the instructions in this chapter are very important for all users and
personnel. For this reason, safety information on batteries and battery packs is
also provided here. When using external battery packs, you must also follow the
safety instructions in the accompanying manual.
Work on the UPS equipment may only be performed by authorized technical
personnel.
3.2 Transportation and storage
The UPS may only be transported to its destination in the original packaging.
The same applies for removals or returns.
The equipment may not be transported or stored upside down.
Position the equipment securely during transportation taking the centre of
gravity into account. Due to their weight, UPS equipment with built-in batteries
may drop suddenly if their position shifts slightly.
During storage, secure positioning of the equipment must also be ensured.
3.3 Setup
The UPS is intended for use in ventilated rooms.
During setup or installation, the installation location prescribed by the
manufacturer must be observed.
If the UPS is exposed to extreme and rapid temperature changes, there is a
risk of condensation. Before taking any further steps, the equipment should be
allowed to acclimatise for at least 2 hours.
Never set up or operate the equipment in a damp environment.
Keep fluids away from the equipment.

UPS RMH700/1000/1500 Instruction Manual
RMH Series Page 8 of 37
The UPS must not be set up near heat sources.
Ensure that the vents of the equipment are not blocked and that the air
circulation is not impeded.
3.4 Connection
Only connect the UPS to an earthed shock-proof socket or, where a terminal
clamp is used, connect the protective earth conductor without fail. Under no
circumstances should the equipment be operated without a protective earth
conductor.
The house installation socket must be easily accessible and located in the
vicinity of the UPS. In the case of a fixed connection, ensure that the shortest
possible cable lengths are used.
If a generator is used to operate the equipment, the correct poling must be
observed when connecting the UPS.
To connect the UPS to the house installation socket, only a VDE-tested and
CE-labelled mains cable may be used. In the case of a fixed connection, a
suitable cable must be used.
To connect the consumer to the UPS, only use VDE-tested and CE-labelled
electrical cables. In the case of a fixed connection to the consumer, a suitable
cable must be used.
The fuse protection for the consumer must always be installed directly in front
of it, and never centrally in front of the UPS.
Do not operate any household appliances and power tools, e.g. fan heaters,
vacuum cleaners, drills, hairdryers, toasters, etc., via the UPS.
Do not connect any consumers to the UPS which could overload the
equipment (e.g. laser printers).
The sum of the earth fault currents of all consumers connected to the UPS
must not exceed 3.5 mA.
Keep the connecting cables as short as possible and always lay these
correctly. Avoid the dangers associated with laying connecting cables where
they may be tripped over, crushed or torn open, etc.
3.5 Operation
The mains power cable must never be disconnected during the operation of
the UPS, otherwise the protective earthing of the UPS as well as the
connected consumers will be lost.

UPS RMH700/1000/1500 Instruction Manual
RMH Series Page 9 of 37
The UPS equipment contains an energy accumulator (batteries). This means
that the output of the UPS can be live even if it is not connected on the line
side.
To completely switch off the UPS, first press and hold the "ON/OFF" button for
more than 3 seconds, wait until the UPS switches off and only then disconnect
the equipment from the mains (remove input fuse or disconnect mains supply
cable from the equipment).
Make sure that no fluids or foreign bodies enter the UPS.
3.6 Handling batteries
Warning – danger of electric shocks and burns.
Batteries can cause electric shocks and are capable of producing high short-
circuit currents which can also inflict burns.
Unauthorized persons must be kept away from batteries.
Do not place batteries against heat sources and do not throw them into a fire.
They might explode!
Do not open or destroy batteries. The electrolyte released is extremely
dangerous to people and the environment (danger of chemical burning to skin
and eyes, toxic).
Defective batteries must be disposed of in an environmentally-friendly manner.
Never throw batteries into the household refuse.
The local waste disposal regulations must be observed.
3.7 Maintenance, servicing and faults
Warning – danger of electric shocks.
The UPS remains connected to the battery circuit even after it has been
disconnected from the mains power supply, and has a dangerous voltage
potential. Therefore always disconnect the battery circuit before carrying out
servicing or maintenance work and make sure that the equipment has been
disconnected from the supply.
Work on batteries may only be performed and monitored by personnel with
appropriate technical knowledge about the required precautions.
Unauthorized persons must be kept away from batteries.
When working on the UPS, the following precautions must be taken:

UPS RMH700/1000/1500 Instruction Manual

4 Introduction
This manual is intended to provide basic information on single-phase online
UPS equipment including their functional principle, application of the various
functions and troubleshooting. In addition, this manual contains information on
transportation and storage as well as handling and installation of the UPS
equipment.
The planning guidelines in this handbook relate only to the specific
requirements for UPS equipment. During installation, the national and local
regulations for electrical installations must be followed without fail.
This equipment description contents may change as a result of technological
developments. We have endeavoured to make these contents as accurate and
clear as possible. However, we would be grateful for information on any errors
which are noted.
We accept no liability for errors in this description and their consequences.
The UPS equipment (Uninterruptible Power Supply) is to protect sensitive
electrical devices such as computers, workstations, electronic points of sale,
mission-critical instruments, telecommunications equipment, process controls,
etc. from faults which may arise as a result of poor power supply quality or
even power failures. Sensitive devices such as these require comprehensive
protection against electrical faults. These may be external faults (e.g. bad
weather, operating faults) or faults caused by neighbouring devices (e.g.
motors, air conditioning units, processing machines, welding equipment, etc.).
The power supply faults can be summarised as follows:
oFast and slow voltage spikes and fluctuations;
oMains power failure;
oFast and slow frequency spikes and fluctuations;
oMains heterodyning or transient voltages
The UPS equipment prepares the mains voltage and ensures that the voltage
values at the output to the consumer load remain constant. Faults in the mains
voltage are thus prevented from reaching mission-critical devices and cannot
cause any damage to software and hardware, data loss or operating faults.

5 System description
The UPS operates continuously according to the double converter principle. It
ensures the preparation of the line current and delivers an uninterrupted and
fault-free single-phase voltage to mission-critical consumer loads In addition to
supplying consumer loads, the equipment also keeps its internal batteries in a
fully charged state. In the event of a power failure or power fault, the UPS
continues to deliver a clean uninterrupted voltage supply to the UPS output.
During support operation, energy is drawn from the batteries.

Block diagram
RMH series
700/1000/1500
The block circuit diagram shows the individual modules of the equipment and
provides a general impression of how they interact.
When the mains power failure exceeds the bridging time of the UPS, it shuts
down to prevent deep discharging of the batteries. When the mains power
supply is restored, the UPS restarts automatically, supplies the consumer
loads and controls the charging of the battery pack.
Notable performance features of the RMH series online UPS include:
oAbsolutely no interruption or signal modification in event of primary
mains power supply failure.
oPerfect sine voltage at the UPS output. Greatly enhanced quality of
output voltage when compared to the mains voltage of the house
network.
oProcessor-controlled bypass operation;
oInput-side “power factor” correction (>0.95);

6 RMH700/1000/1500 – description of equipment
In this chapter, you will be introduced to the various elements of the equipment
and will be provided with instructions on its operation as well as all information
on equipment connections.
6.1 Display and operator control elements on the front panel
Fig. 2:
Front view
RMH700/1000/
1500
All of the operator control and display elements required for normal operation
are positioned on the front of the equipment.
6.1.1 UPS operator control elements

panel for
RMH700/1000/1500
UPS "ON/OFF" switch: (3-way function)
by pressing the button (hold down for approx. 2 seconds) when the UPS is
switched off, it is switched on. (LEDs flash)
If the UPS has already been started and the button is pressed again (one-
touch operation), the UPS switches to “test” operation. (Line LED goes out).
by pressing the button (hold down for approx. 2 seconds) when the UPS is
switched on, the UPS is switched off (LEDs go out).
Warning: The equipment will not be completely started or switched off if the
“ON/OFF” button is not pressed for a sufficient amount of time.
Providing the mains power supply remains on via the fuse (positioned at the
rear of the UPS), the charging unit also continues to operate even after the
UPS has been switched off.

UPS RMH700/1000/1500 Instruction Manual
RMH Series Page 15 of 37
6.1.2 UPS display elements
Most of the display elements only become active when the UPS is powered up
(started).
Line operation:
the UPS is operating using mains power. If the mains voltage tolerances have
been exceeded or if the mains fails completely, this indicator goes out
immediately. The same applies if the fuse is tripped.
The energy required to continue supplying the UPS output during support
operation is drawn from the battery pack.
Inverter operation:
the UPS inverter is working normally and the UPS output voltage is available.
Bypass operation:
the UPS is using the bypass operation. The UPS output is directly connected to
the mains input. This function is mainly active during the UPS startup process.
Damage to the UPS caused by high starting currents in a consumer load is thus
prevented.
The startup procedure for the UPS is complete when the bypass function
changes over after approx. 20 seconds. Then the bypass indicator light goes
out.
The bypass function is also activated if a serious equipment fault develops and
the UPS cannot continue to operate normally. This ensures that the power
supply to the UPS output is uninterrupted.
Fault operation:
Operating fault in the UPS.
The indicator light goes on if an operating fault exists in the UPS or if a short-
circuit develops at the UPS output.
Warning: the indicator bar described below operates within a dual function!
Battery level:
Capacity status of the battery pack.
As long as the UPS support operation is enabled, the capacity status of the
battery pack is displayed here. If the battery pack is fully charged, all indicators
on the indicator bar light up during support operation. As the capacity reduces,
the indicator bar goes out from right to left. When the minimum level is reached,
only the red indicator light remains on.
Load level:
UPS load status.
During on-line operation of the UPS, the indicator bar shows the load present at

UPS RMH700/1000/1500 Instruction Manual
RMH Series Page 16 of 37
the UPS output. If no load exists, the indicator bar goes out completely. As the
load increases, the bar lights up from right to left in 20, 50 and 100%
increments. If the red indicator light also goes on, then the UPS is overloaded.
6.2 Equipment elements on the rear panel

Danger!
Mains voltage exists at all plug connections on the rear panel (exception:
RS232 interface) have mains power potential when connected.
Even when disconnected, dangerous high voltages can exist at the plug
connections due to charged capacities inside the equipment.
a) Fuse at mains power input:
The mains input is enabled when the fuse is inserted. The fuse is triggered in
the event of high overcurrents or an equipment defect (e.g. internal short-
circuit) and the device is immediately disconnected from the connected mains
power supply.
To simulate a mains power failure, simply remove the fuse or disconnect the
plug connection for the mains power supply.
If all UPS connections have been established and the fuse has been inserted,
the charging unit automatically becomes active, i.e. charging of the internal
battery pack is already underway, without having to start the UPS.
a) Mains power

The protective earth conductor must be connected without fail!
Please always observe the max. possible power output of the equipment
indicated on the identification label or in the technical data of this manual.
d) Communication
(9-pin D-Sub jack) All relevant UPS data are transmitted to an appropriate primary control unit (e.g. PC) via the serial interface. In
addition, a defined shutdown signal can be sent to the
UPS. For this, corresponding software packages are
available (see software chapter).
In addition, the interface with the "mains power failure"
and "low battery" contact signals (LAN) is assigned so
that these signals are available for direct processing.
As a safety precaution, always compare the voltages indicated for the UPS and
the battery pack prior to connection. These values must always be the same.

8 Installing and connecting the UPS
All requirements in the technical data regarding environmental and operating
conditions must be observed to ensure trouble-free functioning of the UPS.
The following must be observed when setting up / installing the UPS
equipment:
oAvoid extremes of temperature and atmospheric humidity. A maximum
service life, also in relation to the accumulators, is achieved at an
ambient temperature of 15 – 25°C.
oAlways ensure that sufficient space is available behind the UPS to
make the necessary connections and, as the UPS is heavy, use
suitable guide rails during installation. The load-bearing capacity of the
base must be ensured without fail.
oObserve the specified installation location and only mount the
equipment using the screw-in positions shown (Fig. 5).
Fig. 5: Front view,
showing installation
position and
mounting points
oMake sure that the equipment is ventilated. As this UPS is ventilated in
a crosswise and lengthwise direction, a minimum clearance of at least
50 mm between the UPS and the cabinet in which it is installed must be
maintained on the right and left sides as well as at the front and back.
Ensure an appropriate flow channel.
oPay attention to the arrangement of the equipment. When installed in
parent systems (e.g. machine, control cabinet), you must ensure that
the UPS operates within the specified temperature range. Sufficient
forced ventilation must be used to remove excess heat that builds up in
the space where the UPS is installed.
