The device requires an external overcurrent protection device. Protect the device and the cabling with a circuit breaker at operating voltage lines that has the following characteristics. The overcurrent protection device can be a fuse or a circuit breaker.
Property | Description |
---|---|
Current rating | 13 A, with type B, C, or D tripping characteristics (according to IEC/EN 60898-1 or UL 1077) |
Minimum voltage rating | 32 V DC |
Circuit breaker Instead of a circuit breaker you can use a cartridge fuse with class T (slow acting) tripping characteristics. |
2-pole (connected on both V+ and V–) or 1-pole (connected on V+) |
Vaisala recommends that you use a cable provided for Vaisala. If you use some other cable, the cable must fulfill the following requirements.
