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.
