Note:
VSH-series control boxes may be wall-
mounted or stanchion mounted.
1. If wall-mounting, mount the push-button control
panel (
B
) so bottom of control panel-to-dock floor
distance (
C
) is approximately 48 in. (1219 mm). See
Figure 14. If stanchion-mounting, mount control box
to stanchion in desired location.
2. Install electrical disconnect panel (
A
) if not already
installed. Disconnect panel supplied by others.
3. Install and connect the control wiring (see
drawings supplied with equipment).
4. Seal the conduit in any location where the conduit
crosses over temperature zones that could produce
condensation.
Optional:
Install spacers between the wall and
enclosure to provide temperature insulation and air
flow. If the conduit could fill with water, a drip leg
may be needed.
5. Install placard (see page 17).
Where indicated, all components must be connected
to a SAFETY EARTH GROUND that conforms to
the 1999 National Electrical Code Section 250-50
section (a) or section (c) for a grounding electrode
system.
