1) To avoid electrical shock, connect power line at the end of the
wiring procedure.
2) For power connections, use AWG 16 or 14 wires rated for at
least 75 °C.
3) Use copper conductors only.
4) Don't run input wires together with power cables.
All relay contacts are protected by varistor against inductive load
with inductive component up to 0.5 A.

These outputs are not isolated. The external solid state relay
must guarantee a double or reinforced isolation between
instrument output and power supply.
