3. Installation Information
NOTE: In the event that parts of an original LaserGuard system are used with the LaserGuard2, please
refer to the LaserGuard2 Replacement Guide Application Bulletin on http://www.magnetek.com.
CAUTION
THE LASER CONTROL UNIT AND RELAYS ARE NOT RATED AS EXPLOSION PROOF. THE UNIT
MUST NOT BE INSTALLED IN EXPLOSIVE ENVIRONMENTS UNLESS APPROPRIATE SECONDARY
ENCLOSURE MEASURES ARE TAKEN.
3.1.
Mounting Location Considerations
Ensure the mounting location is as far as possible from exposed trolley wires and sources of
electromagnetic or radiated noise.
If possible, avoid installing the receiver unit to a surface where high vibration or shock is present. If this
cannot be avoided, use appropriate shock mounts.
3.2.
Line Input Considerations
Check the system drawings for proper line input voltage. If there is any question as to proper line input
voltage, contact Magnetek before applying power to the unit.
WARNING
THE UNIT MUST BE WIRED TO THE CORRECT VOLTAGE. FAILURE TO DO SO MAY DAMAGE THE
SYSTEM.
NOTE: The unit should not be connected to lines containing excessive power up transients or continuous
commutator noise. A line conditioner may be necessary in some installations.
3.3. Wiring
Considerations
1.
Do not connect or disconnect wiring or perform circuit checks while the power is turned on.
2.
The motor wiring shall be in a separate metal conduit from the power wiring, which shall also be
in a metal conduit.
3.
Low voltage wires shall be wired with Class 1 wiring.
4.
Control wiring shall be in separate conduit, and shall be kept as short as possible.
5.
Control wiring for stepless devices shall be shielded twisted pair. The shield should be grounded
at both ends.
6.
All terminals shall be tightened to a specified terminal torque (8.8 in-lbs. unless otherwise
specified).
7.
Please observe National Electric Code (NEC) when wiring electrical devices.
8.
When cutting holes in the cabinet, take care to prevent metal filings from shorting the circuitry.
Remove excess metal screws, metal filings, and wire clippings from inside of the unit.
9.
Inspect to make sure no exposed wire has contact with any other wiring or terminals.
10. Suppressors are strongly recommended on all contactors.
