• of safety technology standards.

• in the installation, commissioning and

operation of the device and the components.

WARNING

Risk of injury due to electric voltage or electrical

current!

When handling electrical currents or voltages, serious

personal injuries or death can occur due to:

· Touching live exposed or stripped cores.

· Device inputs that are dangerous to touch.

Before starting work on your system:

· Disconnect it from the power supply!

· Secure it against being switched back on!

· Verify disconnection from power!

· Ground and short circuit!

· Cover or block off neighboring parts that are

INFORMATION

Before starting with the DIN rail assembly and

wiring for your UMG 801, make sure that the

bus connector is mounted on the bottom of your

UMG 801. Up to 10 modules are connected via

the bus connector.

Incoming goods inspection

The prerequisites for trouble-free and safe

operation of the devices and their components

include proper transport, storage, setup and

assembly, as well as careful operation and

maintenance.

Exercise caution when unpacking and packing

the device, without using force and only using

suitable tools.

Mount the measurement device in switch

cabinets or small distribution boards according

to DIN 43880 (any installation position) on a

data), as follows:

1. Insert the bus connector included in the scope

of delivery in the socket on the bottom of the

measurement device.

2. Slide your measurement device with the bus

connector laterally on the DIN rail or press it

frontally onto the DIN rail until the bottom latch

engages.

• Keep the usage information accompanying

the product accessible through its service life

and hand it over to the subsequent owner

where applicable.

• Please refer to www.janitza.de for information

concerning device revisions and the

associated adjustments to the usage

information accompanying the product.

Disposal

Please observe the national regulations. Dispose

of individual parts, where necessary, depending

on the properties and existing country-speciﬁ c

regulations, e.g. as:

• Electronic waste

• Batteries and accumulators

• Plastic

• Metals

or commission a certiﬁ ed

disposal company with the scrapping.

Relevant laws,

applied standards and directives

Please refer to the Declaration of Conformity

on our web site (www.janitza.de) for the laws,

standards and directives applied by Janitza

electronics GmbH for the device.

ATTENTION

Property damage due to noncompliance with

the connection conditions or impermissible

overvoltages

Noncompliance of the connection conditions

or exceeding the permissible voltage range can

damage or destroy your device.

Before you connect the device to the supply

voltage, please observe the following:

· The voltage and frequency must comply with the

speciﬁ cations on the rating plate. Observe the limit

values as described in the user manual.

· In building installations, secure the supply voltage

with a UL/IEC-listed circuit breaker/fuse.

S1 S2

· The circuit breaker

S1 S2

- must be easily accessible for the user and

S1 S2

located in the vicinity of the device.

S1 S2

- must be labeled for the respective device.

· Do not tap the supply voltage at the voltage

transformers.

Fig. "Current measurement" connection example.

· Provide a fuse for the neutral conductor if the

neutral conductor connection is not grounded to

the source.

WARNING

Electrical currents and voltages!

Open current transformers that are operated on the

secondary side (high voltage spikes) can result in

serious personal injuries or even death.

Avoid the open operation of the current trans-

formers and short-circuit unloaded transform-

ers.
