Models with the “Q” suffix” are functionally equivalent in all respects to the same model without the “Q”
suffix, except for the header. Models without the Q” suffix use DF-1 lead connectors for the high-voltage
leads, and models with the Q” suffix use a single DF4-LLHH lead connector for the high-voltage leads
and for the low voltage RV lead.
SJ4-LLHH is equivalent to DF4-LLHH. SJ4 and DF4 connectors comply with ISO 27186:2010(E).SJ4-
LLLL is equivalent to IS4-LLLL. SJ4 and IS4 connectors comply with ISO 27186:2010(E).
