3.5.3.3

Customer Supplied Components

The following customer-supplied components are required for installation of primary AC power
(if this is a CE / ATEX installation, see the Application Drawing Package):
Primary AC Wire
Customer AC power wiring recommended for the air bath or airless oven configuration is three
wire 12 AWG for 115 VAC and 14 AWG for 230 VAC with a hot, neutral, and ground. For the
modular oven configuration three wire cable of at least 14 AWG is recommended. Wiring
should be rated for 80°C or higher.
Circuit Breaker
The circuit breaker must have the correct ampere rating, number of poles, and rated for the area
that it will be installed. The circuit breaker must be installed in close proximity to the Maxum II
so it is easily accessible to the service technician for turning power off to perform maintenance
functions or for safety purposes. In addition, the circuit breaker must be labeled as the
disconnecting device for the Maxum II.
Note
All AC power (Mains) wiring shall be in accordance with all applicable codes.
Conduit
The AC primary power rigid and explosion proof conduit must be ½" (1.26 cm) minimum
diameter. The conduit end, which terminates at the Enclosure, must be equipped with an
explosion proof seal. The conduit terminates at the Enclosure opening located on the top left
side.
It is recommended that a conduit hub be used to securely connect the conduit to the EC
Enclosure. The conduit hub type used must meet the electrical codes for the area of installation.
