CAUTION!
Electrical hazard – risk of damage to equipment. Do not connect AC power cables to terminals for DC
power. Damage to the power supply may occur.
CAUTION!
Electrical hazard – risk of damage to equipment. Before testing the dielectric strength (HIPOT) in the
field, remove the braided ground cable connected to the surge ground terminal and chassis ground.
This cable connects transient suppression circuitry to chassis ground and must be removed in order to
avoid damage to transient suppression circuitry during testing.
NOTE
Torque all terminal connections to 0.6 N·m (5 lbf-in).
