e electrical installation may only be carried out by qualified electricians in compliance with the installation, operating
and maintenance instructions and the applicable national regulations, standards and guidelines:
■ISO, DIN, EN and VDE specifications, including all safety requirements.
■Technical connection conditions.
■Safety at work and accident prevention requirements.
is list does not claim to be complete.
Requirements should be applied under one‘s own personal responsibility.
■e electrical connections must be made as shown in the corresponding wiring diagrams and terminal diagrams.
■e type of cable, size of cable and method of laying should be determined by an authorized electrician.
■Low and extra-low voltage cables should be laid separately.
■If no repair switch is integrated in the device, an all-pole mains disconnecting switch with min. 3 mm contact
opening must be provided in the supply line.
■Use a separate cable inlet for each cable.
■Any cable inlets that are not used must be sealed so that it is airtight.
■All cable inlets must have strain relief.
■Create equipotential bonding between the unit and the duct system.
■Check all protective measures after the electrical connection work (earthing resistance, etc.)
■Motor current and motor power must not exceed the values stated on the motor nameplate. e specified max.
fan speed must never be exceeded, otherwise the motor and fan will be destroyed by this overload and dissolved
or flying parts can destroy other components.
11. ELECTRICAL CONNECTION
• Electricity warning (hazardous voltage)!
»Failure to observe the hazard may result in death, injury or damage to property.
→ Before performing any work on conductive parts, always disconnect the unit completely from the electri-
city supply and make sure that it cannot be switched back on again.

Installation, operating and maintenance instructions
11.1. Unit supply cable / Electrical connection / wiring diagram
Connect the mains supply cable as shown in the wiring diagram. For the dimensioning of the line, observe the unit‘s
rating plate and the relevant guidelines. Appropriate protection with correctly dimensioned automatic safety breakers
(circuit protection breaker) must be provided.
e device must be connected according to the wiring diagram. For fans which are controlled by external control de-
vices, the corresponding operating instructions of the manufacturer must be observed.
If a fault current protection switch is used, only AC/DC sensitive RCD protective devices (type B or B+) are permitted.
During operation, electric motors heat up. Under certain circumstances (excessively high ambient or fluid temperatu-
res, heavy contamination, etc.), the motor temperature may exceed the safety limit of the electrically isolated parts.
In case of EC motors an electronic temperature monitoring is present.
11.3. Fault current protection switch
11.2. ermal motor protection
Even when the device is switched off, voltage is applied to terminals and connections. Do not touch the de-
vice for 5 minutes after all-pole disconnection from the mains.
Only potential-free contacts may be connected at terminals X3 and X4, and X5 and X6. Applying an external voltage
can seriously damage the regulator.
e regulations for safety extra-low voltages must be observed.
e maximum pressure in a ventilation plant must not exceed 5000 Pa.
is would result in severe damage to the regulator.
Low voltage control leads must be installed so that they are separated from mains leads.

12. COMMISSIONING
Commissioning by trained technical personnel may only be performed after any risk has been ruled out. e
following checks should be performed in accordance with the installation and operating manual and the regu-
lations in force:
■Correctly sealed installation of the unit and duct system.
■Check the duct system, unit and medium lines, if present, remove any foreign bodies if necessary.
■e intake opening and inflow into the unit must be clear.
■Check all mechanical and electrical protection measures (e.g. earthing).
■Voltage, frequency and type of current must correspond with the rating plate.
■e pressure measuring tube will be laid in the duct.
■Setting of the desired differential pressure see 13. Operation
13. OPERATION
CAUTION! Isolate electrical installation!
NIGHT
DAY
Adjust set-point
After removing the cover, you have free access to the pressure regulation circuit board.
Adjust set-point for the desired differential pressure at the two upper decade switches (8).
Switching the regulator on and off
Bridging terminals X5 and X6 switches the constant pressure regulator CON P1000 on, and removing the bridge swit-
ches it off again.
Turning the night mode ON and OFF
By bridging the terminals X3 and X4 the night mode is switched on, by removing the bridge, it is switched off.
Changing day-time set-point
Adjust set-point Day with the decade switches (8).
e.g. 3 2 = 32 x 10 = 320 Pa
Adjusting the night-time set-point
Adjust set-point Night with the decade switches (9).
e.g. 4 1 = 41 x 10 = 410 Pa
