1.2 Safety instructions
Please read these instructions, carefully and completely, before putting the device into
operation. Please also comply and follow the safety instructions, specially the safety
regulations related to the devices being operated on mains supply.
The product should be installed and used only for the intended applications as
described in these instructions. Any other application is not advised and shall lead to
loss of guarantee and exclusion from liability. This also applies to any changes or
other modifications carried out on the device by the user.
Defective safety devices should be replaced with same type of items in respect of trip
current rating, tripping characteristics, and mechanical fitment dimensions. Bypassing
protections lead to a considerable safety risk and are not allowed under any
circumstances.
The connection terminals can be wired to mains voltage. Contact with live parts lead
to fatal dangers. The mounting and maintenance operations should be carried out by
only trained personnel, who are authorised on the basis of technical training in this
field. The applicable safety regulations should be followed. The switching device must
be assembled in a switchgear cabinet or a fully closed plastic housing. Mounting and
servicing operation should be carried out only after switching off the voltage.
The product is not meant for controlling electrical systems, which perform safety
related functions. In normal operation also, there is always a danger of malfunctioning
due to failure of any component or any other disturbance. The user has to ensure that
there are no consequential damages due to malfunctioning or undefined switching
status of the relay. This is all the more possible, if heavy loads like heaters or motors
are triggered with the relays.
