4. INSTALLATION
R50 Blue Bar
CAUTION
–
Electrical Shock Hazard
DO NOT use metallic screws. DO NOT omit insulator blocks.
1 Mount bar to machine. Bar should be positioned away from all metal ground
references. In an ideal mounting arrangement, a cylindrical space with radius R
between bar and web should be kept free of any grounded metal structure. In the
event of confined mounting space, the minimum distance that a bar should be
located from a nearby metal ground reference is 1”.
2. Determination of radius R depends on web speed. For varying web speed, radius R
should be 2” from web surface. Refer to
Figure 4
for maximum mounting distance
of bar from web surface. In certain applications, the Blue Bar has been found to
work well at distances in excess of 6”.
CAUTION
– Mounting the bar directly against a grounded metal support
without sufficient air space or plastic insulation could result in burn-out of the
bar.
3. Insert nylon screws through washers, then metal bracket, insulation block and
finally into the sliding nuts supplied with each Blue Bar (see
Figure 4
).
4. Hand-tighten screws plus ¼ turn. Do not over-tighten. For permanent mounting,
apply liquid thread-lock to screw prior to assembly (Loctite 243 or equivalent).
CAUTION
– Failure to properly ground the power supply may result in an
electrical shock hazard to personnel and inefficient operation of the equipment.
Do not apply line power until all grounds and high voltage connections have
been completed.
“N” Power Supply
Mounting and Grounding the Power Supply
The power supply is designed for flat surface mounting and can be easily mounted using
the mounting flanges at the base of the unit. The ambient temperature of mounting are
of the power supply must not exceed 105˚F (40˚C).
CAUTION
–
Electrical Shock Hazard
Failure to properly ground a power supply may result in an electrical shock
hazard to personnel and inefficient operation of equipment.
