1.3 General instructions
Safety risks (read carefully!)
After disconnecting power, wait 10 minutes before removing the drive
enclosure.
Before operating and maintenance work always check that all voltages at the
terminals are zero or at levels which are harmless.
Always make sure the compressor has stopped completely before removing
the drive enclosure.
As soon as the drive is connected to the power supply the input terminals will
be at line voltage even when the compressor is not rotating.
Do not measure insulation resistance or dielectric rigidity directly via the
input terminals with power supply connected.
Review relevant safety standards concerning installation of high voltage
devices, as well as the regulations for the correct use of personal protective
equipment.
The drive can only be used for purposes specified by the manufacturer.
This product can cause both AC and DC earth leakage current. To protect
against both kinds of leakage current an AC/DC sensitive RCD must be
installed in front of the EV3 drive.
Do not make any modifications or replace any components as these actions
may lead to consequences including but not limited to fire and electric shock
and will void the warranty. Product modifications are not allowed. The
manufacturer is not responsible for any unauthorized modification made to
the product by the user.
A proper earth connection of the drive must be ensured to avoid the risk of
electric shock.
The IP20 protection is only given after all terminals are connected with
isolated ring and isolated blade terminals!
In special cases of using the drive without the IP20 enclosure, which is in
general forbidden, the protection against direct and indirect touching must be
part of the system design to avoid any risk of electric shock!
DC/AC chokes must be covered on system side to avoid any risk of electric
shock!
Use safety shoes to avoid foot injury.
Handle the drive carefully.
Protect the drive from dust. During installation make sure to clean off the
debris caused by drilling. Remove any conductive debris inside the drive
which can cause damage or malfunction.
Before touching the heatsink or unpowered chokes, make sure that the
temperatures are within safe limits to avoid burn injury.
In general, the drive cannot be used in an environment where a direct
contact with flammable or explosive substances can occur. Furthermore, use
in a transcritical system is not allowed. Use with A2L flammable refrigerants
is only foreseen in systems based on the IEC 60335-2-40:2018-05 standard
with some restrictions shown in these guidelines.
Table 2: Safety risks
1.4 Use with A2L refrigerants
The EV3 drive is not designed or qualified based on the ATEX directive! Use
with A2L flammable refrigerants is possible if the system design is based on
the IEC 60335-2-40:2018-05 standard.
The EV3 drive has been assessed in accordance with IEC 60335-2-40, and does not represent a
source of ignition for A2L if the following points are respected:
▪ The drive mounting area must be in Zone 2 or outside any ATEX zone and in line with "Pollution
Degree 2" classification.
▪ No airstream guided over the drive itself.
