SPECIFIC INSTRUCTIONS
Do not connect the drive to an isolating transformer.
Do not use mains disconnection devices in conjunction with a drive.
Do not use more than one switch per drive.
Use only mechanical or electro-mechanical switches (e.g.: relays) to
control drives. The relay contacts must not be bypassed by capacitors.
In user mode, do not use electric switches that allow the
▲
and
▼
buttons
to be pressed simultaneously.
The drive must not be driven by a solid-state relay or triac relay.
Always refer to the control system instructions for proper wiring.
For control systems using an “automatic operating time recognition
procedure”, follow the recommendations made by the controller
manufacturer: The controller neutral must be connected to neutral of
each drive.
Continuous orders of at least 200ms must be sent to the drive to ensure
proper execution.
There must be an interval of at least 500 ms between “Down” and “Up”
orders.
The drive can be wired in parallel. In this case, take into account the
maximum load of the switch/controller used (peak starting current:
9 A for 3 ms).
The phases and neutrals of each drive must be connected together
respectively, as shown below:
