7. Electrical
Before installation, the electrical supply should be checked for adequate wire size and capacity. During installation,
a suitable fused disconnect switch or circuit breaker should be provided. Where a 3-phase motor is used to drive a
vacuum pump, any unreasonable voltage unbalance (5%) between the legs must be eliminated and any low voltage
corrected to prevent excessive current draw. The installation must be in accordance with National Electric Code,
and all state and local codes. All electrical work should be performed by a qualified electrician.
This unit must be
grounded in accordance with applicable codes.
See control panel for the proper wiring diagram.
Quincy would like to emphasize the importance of providing adequate grounding for vacuum pumps.
The common practice of grounding units to building structure steel may not actually provide adequate grounding
protection, as paint and corrosion build-up may exist.
! CAUTION
NEMA electrical enclosures and components must be appropriate to the area in
which they are installed.
8. Guards
All mechanical action or motion is hazardous in varying degrees and needs to be guarded. Guarding shall comply
with OSHA Safety and Health Standards 29 CFR 1910.219 in OSHA manual 2206 Revised November 7, 1978 and
any state or local codes.
! WARNING
Cabinet panels and drive guards must be fastened in place before starting the
machine and never removed before tag and lock out of the main power supply.
! CAUTION
Removal or painting over safety labels will result in uninformed conditions. This
could result in personal injury or property damage. Warning signs and labels shall
be provided with enough light to read, conspicuously located and maintained for
legibility. Do not remove any warning, caution or instructional material attached.
