INSTALLATION
Page 3-3
MAIN POWER CONNECTION
1. Connect to the power source per electrical schematic.
The main power wiring must be connected per the NEC, CEC and any
applicable local and national codes or regulations. For installation the
chamber is a measurable category III piece of equipment. The unit can be
cord connected or hard wired.
A main power disconnect must be provided with a time delay fused switch
or circuit breaker with ampere rating speci
fi ed on the electrical schematic
for the particular unit being connected. The switch or circuit breaker
must remove power from all ungrounded conductors. (See GENERAL
DESCRIPTION Tables 2 to 4 for ZP(H) live load Capacities) The main
power disconnect must be suitably located and easily reached. Main Power
disconnects must be located near the chamber. The main power disconnect
must be marked as the disconnecting device for the equipment. Please see
electrical schematic for appropriate rating of your chamber model.
2. Cord Connected
ZP(H) Units
Use SO type cord sized appropriately for the load rating of the chamber. It
should be installed with a cord grip and integral strain relief. For Non-CE
marked chambers, it is recommended that the power plug be a twist-lock
device to insure a solid electrical connection. For CE marked equipment, a
suitably rated IEC60309 plug must be fi tted to the chord.
3. Hard Wired
ZP(H) Units
Use a liquid tight metallic or nonmetallic fl exible conduit. Power wires
should be sized appropriately for the load rating of the chamber and rated
at a minimum of 75°C. The 1/4 EMT conduit (35 mm metric conduit trade
size) is equipped on the chamber as a conduit for power lines.
4. Grounding
Protective earth conductor must be sized appropriately and connected to
the protective conductor terminal on the chambers electrical sub panel.
If main power disconnect is provided with the chamber, the protective
conductor will connect to the provided terminal inside the main power
disconnect. See your electrical schematic for information regarding earth
connections.
To change between 208V and 230V, locate the jumper between TB-1
terminals H3, 2L4 and H5. For 208V, place jumper between H3 and
2L4. For 230V operation, place jumper between 2L4 and H5. For more
information refer to note 1 on the electrical schematic located in the
“Drawings” section of this manual.
Electrical connections
are terminated in the
electrical panel. Route
incoming power wires
through the conduit
located at the rear of
the unit.
