CAUTION

No circuit protection is provided against output short circuits; if this occurs the circuit may be
damaged. The outputs must not be connected or disconnected when the DPCM is powered. The
output circuit must not contain any other switch circuit, such as manual override; if required,
these must be implemented either in the controller strategy, or in the 10 V signal. The outputs
should be connected only to their loads (i.e. kept isolated from earth or other supplies).
