Tip!
·
The brake resistors are fitted with a thermostat (potential−free NC contact) as standard.
·
If required, several brake resistors can be connected in parallel or in series. (Caution: do not
fall below the lowest possible value!)
Installation instructions
·
Brake resistors may overheat, possibly a brake resistor may burn. Therefore, mount the brake
resistors in such a way that the possibly very high temperatures may not cause any damage.
·
Provide a safety shutdown when the brake resistor overheats!
·
Use temperature contacts of the brake resistor (e.g. T1 / T2) as control contacts to separate
the controller from the mains!
Connection to E82MV251_2B, E82MV371_2B
Procedure Connection diagram
The brake resistor R
B
is connected to the
terminal strip X1 of the motec.
1. Open the motec.
2. Mount the cable connector for the cable
gland.
3. Unscrew the terminal strip X1 and remove
it from its support.
4. Connect the brake resistor to BR2 and
BR1.
5. Reconnect the terminal strip X1.
