Capacitive load
The relays cannot be used for the direct connection of capacitive loads
such as LEDs and on/off control of EC motors.
All loads with a switch mode power supply must be connected with a suit-
able contactor or similar.

Installation considerations
Accidental damage, poor installation, or site conditions, can give rise to
malfunctions of the control system, and ultimately lead to a plant break-
down.
Every possible safeguard is incorporated into our products to prevent this.
However, a wrong installation, for example, could still present problems.
Electronic controls are no substitute for normal, good engineering prac-
tice.
Danfoss will not be responsible for any goods, or plant components, dam-
aged as a result of the above defects. It is the installer's responsibility to
check the installation thoroughly, and to fit the necessary safety devices.
Special reference is made to the necessity of signals to the controller when
the compressor is stopped and to the need of liquid receivers before the
compressors.
Your local Danfoss agent will be pleased to assist with further advice, etc.
