Isolating relay without own phase "2 motors"

Product and functional description

The cut-off relay 498103. is a control relay for controlling blind and shutter motors with mechanical or electronic limit switches. The cut-off relay is used to prevent unauthorized parallel switching of
Blind or shutter motors in parallel. Two motors may be connected to one 498103. If more than 2 motors are to be controlled, several cut-off relays can be connected according to the circuit diagram.

Central control

All connected motors can be operated simultaneously via the central control unit. Suitable switching devices are blind switches or blind push-buttons, shutter timers, EIB shutter actuators
and various control units with potential-free contacts. When selecting the central control unit, it must be ensured that the sum of all motor currents must be switched via the contacts in the central control unit.
Important: Switchover time between up and down command >= 0.5 sec. must be observed, otherwise the motor or relay may be damaged (observe the technical data of the motors).

Technical data

Power supply: 230V, AC, 50Hz, fuse protection circuit breaker max. 10A characteristic A or B
Outputs: Connection for a shutter or blind motor (8AAC1, 4 A cos phi 0.6) Temperature range -30° to 70°C
Connections: Screw terminal 0.5 to 2.5qmm single-wire, 0.5-1.5qmm fine-wire with wire end ferrule
Electrical safety: Pollution degree (IEC 60664-1): 2, degree of protection: depending on the installation box

Caution

The device may only be connected by a qualified electrician. The device must not be opened. When connecting, ensure that all poles of the cut-off relay are disconnected.
If different phases are permitted, ensure that all poles are disconnected in the event of a fault or when working on the system. The applicable safety and accident prevention regulations must be observed.
