Lamphead Cable Connections
CAUTION: The unicable conducts high and low voltage between the
system controller and the lamphead. It is important that the unicable
connectors be completely engaged and tightened before turning on the UV
system. Failure to properly engage these connectors can result in severe
damage to the system components.
Before inserting the plug into the receptacle check both and ensure that the
pins are not bent, and that the rubber inserts are in good condition and not
damaged. Make sure also that there is no evidence of arcing or other
damage on the pins and sockets.
See Figures 3-3 and 3-15. Connect the unicable to the system controller
and the lamphead.
NOTE: The unicable plugs are keyed and can only be inserted into the
receptacles when correctly oriented. Do not force the plugs into the
receptacles. Do not use the screw rings to pull the plugs into the
receptacles. In most cases, it might help to wiggle the plug slightly while
pushing it into the receptacle to ensure that all the pins mate securely with
the sockets.
Push the plug into the receptacle as far as it will go, then start threading the
screw ring onto the threaded portion of the receptacle. Continue to push on
and wiggle the plug while tightening the screw ring until the plug is firmly
seated into the receptacle.
When fully mated, the red indicator on the plug should not be visible
and there should be no movement between the plug and the
receptacle.
NOTE: When tightening the screw ring, it is recommended to use a 30−32
DIN1810B hook wrench (spanner wrench) to insure that the connection is
secure. There are four holes in the screw ring for the wrench pin.
