Important Information
Before applying AC power (mains), make sure the supply is 115 VAC
+5% / -10%
Never operate the
blackbox
with terminal access exposed.
An external switch or circuit breaker should be installed near to the
blackbox
to allow the supply to be removed during installation and
maintenance. In addition, the relay contacts should also have a means
of isolating them from the
blackbox
.
Interconnecting cables must be adequately insulated in accordance
with local regulations. Strip back 30 mm of the outer insulation of the
cable. Strip 5 mm of insulation from the end of each conductor. Twist
all exposed strands of the conductor together. Insert the stripped
conductor into the terminal block as far as it will go and tighten the
terminal block screw. Ensure that all strands are firmly clamped in the
terminal block and that there is no excess bare conductor showing,
and no stray strands.
