water entering the drive.

SPECIFIC INSTRUCTIONS

Do not connect the drive to an

isolating transformer.

Do not use mains disconnection

devices in conjunction with a drive.

Use only mechanical switches

or electro-mechanical switches

(ex : relays) to control drives. The

contacts of the relays must not be

bypassed by capacitors.

In user mode, do not use electric

switches allowing simultaneous 

and  contact.

The drive must not be driven by a

solid-state relay or triac relay.

Always refer to the control system

instructions to do the proper wiring.

For control systems using

an «automatic running time

recognition procedure», please

consider the recommendations

given by the producer of the

controller : the N wire of the

controller has to be connected to

the N wire of each drive.

Continuous orders of at least

200ms must be sent to the drive to

ensure proper execution.

Intervals between “Down” and “Up”

orders must be at least 500ms.

The drive can be wired in parallel.

In this case take in consideration

the maximal load of the switch/

controller used (starting current

peak of the drive : 9 A in the ﬁrst

3ms).

Phases and neutrals of each drive

must be connected together

respectively as shown below :
