1. What bias voltage can be applied?

for high flux applications (e.g. synchrotron) between –10 and –20 V.

for low flux applications it is advised to scan from 0 to –20 V and to look for the best signal-to-noise ratio (trade-off between signal and dark current)

2. The bias voltage was of wrong polarisation, does it harm the sensor?

No, try measuring the dark current with correct polarity (negative). At –10 V bias voltage typical dark currents are between 10 pA and 10 nA. Check the technical notes at chapter 4.1 or contact support@dectris.com.
