3. Fitting instructions
Install the pushbutton control unit (1) in a flush-mounting box in acc. with
DIN 49073 (fig A). The connecting terminals of the insert must be at the
bottom (wall mounting). Use the pushbutton control unit only in
combination with an attachment. Plug the attachment (2) together with
frame (3) into the insert. The electrical contact is ensured by connector
(4). The overall power consumption of the lamps connected must not
exceed 700 W.
Depending on the type of installation, the max. load connected must be
reduced:
- 10 % for every 5 °C above the ambient temperature of 25 °C
- 15 % for installations in wooden, gypsum plasterboard or hollow walls,
- 20 % for installations in multi-device combinations.
Observe the technical connection requirements of the power supply
companies.
4. Short-circuit protection
The load output has no internal protection. For protection install a circuit-
breaker of 10 A ahead of the device. The 1-10 V control output is
protected against shortcircuiting of the control current.
Do not connect the control output to 230 V ~. The pushbutton
control unit will be irreparably damaged.
Connection without extension units
The insert is connected as shown in fig B. The extension unit input „1“
remains open.
