2. ZVD Installation and Wiring
The ZVD AC vector drive is sold in a NEMA 12 control cabinet and is intended to be
part of a Zenith Products Division fluid handling solution. For customers who desire to
mount the drive in their own cabinet, the ZVD is also sold as a standalone NEMA 1
drive.
2.1.1 NEMA 1 Standalone
If purchased as a NEMA 1 standalone drive, the location and installation of the ZVD
should adhere to the following constraints:
2.1.1.1 Do not mount the ZVD drive near heat-radiating elements or in
direct sunlight.
2.1.1.2 Do not install the ZVD drive in a place subjected to high tem-
perature, high humidity, excessive vibration, corrosive gasses
or liquids, or airborne dust or metallic particles.
2.1.1.3 Mount the ZVD drive vertically and do not restrict the air flow to
the heat sink fins.
2.1.1.4 Allow sufficient space around the unit for heat dissipation.
Approximately 6 inches should be allowed above and below
the drive and 2 inches on each side.
2.1.2 NEMA 12
If purchased as a drive in a NEMA 12 cabinet, the location and installation of the ZVD
should adhere to the following constraints:
2.1.2.1 Do not mount the NEMA 12 ZVD drive near heat-radiating
elements or in direct sunlight.
2.1.2.2 Do not install the NEMA 12 ZVD drive in a place subjected to
high temperature, high humidity, excessive vibration, corrosive
gasses or liquids, or water spray.
2.1.2.3 Mount the NEMA 12 ZVD drive vertically, allowing a minimum of
6 inches above and below the control panel and 2 inches
behind the panel for air flow and convection cooling.
2.2 Wiring
2.1 Installation
The ZVD drive will arrive with all internal wiring of the NEMA 12 cabinet complete, for
most customer requirements. The customer will be required to wire to the terminal strip
mounted inside the cabinet. If the customer desires to use some available functions of
the ZVD that are considered non-routine, the customer may have to wire to the ZVD,
itself. If the ZVD drive is ordered as a NEMA 1 standalone drive, the customer is
required to make all connections to the drive.
2.2.1 General
CAUTION: TO PREVENT PERSONNEL ELECTROCUTION OR DAMAGE TO THE
EQUIPMENT, MAKE SURE ALL POWER TO THE ZVD IS REMOVED BEFORE MAKING
ANY WIRING CONNECTIONS OR CHANGES.
Wiring practices must conform to applicable local electric codes and the National
Electric Code (NEC). If installed in a country outside the USA, wiring practices should
conform to the electric codes of the country the ZVD is installed in.
2.2.1.1
Input power to the control cabinet must be supplied through an
appropriately sized circuit breaker or fused disconnect that is
within easy reach of the cabinet.
