disconnected from grid/mains and solar modules. Wait at least 20 min. before
proceeding, after having disconnected from grid and PV panels.
operating the inverter:
Before connecting the AC grid to the inverter, make sure that the installation cover is
mounted again. The inverter must not be open during operation.
Maintenance and modification:
Only authorized personnel are allowed to repair or modify the inverter. To ensure
optimum safety for user and environment, only the original spare parts available from
your supplier should be used.
Functional safety parameters:
Unauthorized changes of functional safety parameters may cause injury or accidents to
people or inverter. Additionally it will lead to the cancelling of all inverter operating
approval certificates. The Trannergy inverters in the TRM range are all designed
according to international safety requirements.
If non-original spare parts are used, the compliance with CE guidelines in respect of
electrical safety, EMC and machine safety is not guaranteed.
1.5. General Safety Rules for Working on Electrical Equipment
All persons installing, maintaining or servicing inverters should be trained in and have experience
with the general safety rules to be observed when working on electrical equipment.
Installation and service personnel should also be familiar with local requirements, rules and
regulations as well as safety requirements.
To provide a general guideline for safety precautions, five well-known and widely accepted rules are
repeated below. The list should by no means be considered as exhaustive.
The person performing work on electrical equipment is responsible for the safety of
persons and property!
Disconnecting
Disconnect all cables supplying voltage to the working place before starting any work.
Please note that a lack of voltage is no guarantee that disconnection has been performed.
Protecting against reconnection
Prevent the system from reconnecting by marking, closing or locking off the work area.
Unintentional reconnection may result in severe accidents.
Checking that system is voltage free
Ascertain conclusively by means of a voltage tester that the system is voltage free. Check
all terminals to ensure that the system is voltage free (on each individual conductor).
Covering adjacent voltage-carrying components and preventing persons from gaining
access to them
Cover up all voltage-carrying system components that can harm you while working.
Make sure that danger areas are clearly marked.
