If you mount products in a rack, ensure that the rack has sufficient load capacity and
stability. Observe the specifications of the rack manufacturer. Always install the prod-
ucts from the bottom shelf to the top shelf so that the rack stands securely. Secure the
product so that it cannot fall off the rack.
Connecting the product
Before connecting the interfaces and measuring inputs of the product to other products
or electrical circuits, make sure that the other products or electrical circuits provide
special protection against electric shock. This protection principle is referred to as
SELV (safety extra-low voltage) and is based on a low voltage level and increased
insulation. Exceptions are indicated by a measurement category on the product and
given in the specifications document.
Connecting to power and grounding
The mains power supply input of the instrument complies with overvoltage category II.
Connect the product to a fixed installation used to supply energy-consuming equipment
such as household appliances and similar loads. Keep in mind that electrically pow-
ered products have risks, such as electric shock, fire, personal injury or even death.
Take the following measures for your safety:
●
Do not use an isolating transformer to connect the instrument to the mains power
supply.
●
Before switching on the product, ensure that the voltage and frequency indicated
on the product match the available power source. If the power adapter does not
adjust automatically, set the correct value and check the rating of the fuse.
●
If a product has an exchangeable fuse, its type and characteristics are indicated
next to the fuse holder. Before changing the fuse, switch off the product and dis-
connect it from the power source. How to change the fuse is described in the prod-
uct documentation.
●
Only use the power cable delivered with the product. It complies with country-spe-
cific safety requirements. Only insert the plug into an outlet with protective conduc-
tor terminal.
●
Only use intact cables and route them carefully so that they cannot be damaged.
Check the power cables regularly to ensure that they are undamaged. Also ensure
that nobody can trip over loose cables.
●
If you connect the product to an external power supply, use the one delivered with
the product or recommended in the product documentation. The external power
supply must conform to the country-specific regulations.
●
Ensure that you can disconnect the product from the power source at any time.
Pull the power plug to disconnect the product. The power plug must be easily
accessible. If the product is integrated into a system that does not meet these
requirements, provide an easily accessible circuit breaker at the system level.
●
Replace parts that are relevant to safety only by original parts, e.g. power cables or
fuses.
