8.3.1 Safety
This manual contains clearly marked cautions and warnings which are intended for your personal
safety and to avoid any unintentional damage to the product or connected appliances.
Please read the information included in dangers carefully.
The optional heater allows the drive to operate in low temperature conditions down to -40°C. This
option is intended to be installed inside the drive.
Only VACON

authorized, trained and qualified personnel are allowed to install and maintain this
component.
8.3.2 Dangers
8.3.3 Technical data
The optional heater has to be supplied with single-phase 230V. The thermal element is always sup-
plied and if the drive is connected at -40°C the drive will be heated up until the temperature of -10°C
is exceeded. The heating is temperature controlled and an internal fan ensures that the air is equal-
ly distributed inside the enclosure.
The integrated relay output (switching capacity: 24VDC / 3A, 250VAC / 3A) can be used to control the
power-up of the drive. The contact is closed when the internal temperature is higher than the min-
imum allowed value for the power-up (~ -10°C). This can be included and manage in the logic of the
entire system. A bi-color LED (on the enclosure of this option), shows the status of the drive, ready
or not-ready.
The components of the optional heater are live when the element is connected to
mains potential. Coming into contact with this voltage is extremely dangerous
and may cause death or severe injury.
The heater can be used only inside the drive and in combination with only the
VACON
®
100X. Before connecting the heater to mains, make sure that the
VACON
®
100X drive is closed firmly.
