Chapter 2 – Installation
TestEquity 1016C-1027C Temperature Chamber
Page 2-3
NOTE:
Refer to Figure 2-1 for the location of the input configuration terminals on the electrical
sub panel that are described below.
230 V / 60 Hz Input Configuration (for 240 V lines)
1.
Turn the Main Disconnect switch to the OFF position.
2.
Remove the lower door retaining screw located on the right side. Open the lower door.
3.
Locate the Control Transformer TR1. Wire number T1 must be connected to the 230 V
terminal 4 on Control Transformer TR1.
208 V / 60 Hz Input Configuration
1.
Turn the Main Disconnect switch to the OFF position.
2.
Remove the lower door retaining screw located on the right side. Open the lower door.
3.
Locate the Control Transformer TR1. Wire number T1 must be connected to the 208 V
terminal 3 on Control Transformer TR1.
Connection to the Power Source
2
CAUTION:
This chamber should be connected to the AC power source by a qualified
electrician who is familiar with industrial plant wiring.
The Main Disconnect Switch on the front panel removes primary power to the entire chamber.
All branch circuits on the load side of the Main Disconnect Switch are individually fused.
However, your local electrical code may require a separate disconnect switch within sight of the
chamber.
Power Source Connection
1.
Turn the Disconnect Switch to the OFF position.
2.
Remove the lower door retaining screw located on the right side. Open the lower door.
3.
Remove the chamber’s right side panel.
4.
Mount the input wire through the hole on the rear of the chamber, using an appropriate strain
relief. An additional 54-inches of wire will be needed need to reach to the terminals on the
electrical subpanel. The wires will need to pass through the Input Access Hole. This hole is
located in the corner of the partition which separates the compressor compartment from the
electrical compartment. Three tie points are provided on the side of the chamber to secure the
input wiring with provided tie-wraps.
5.
Connect the “Hot” input wires to terminals L1, L2 and L3 on the Main Disconnect Switch.
6.
Connect the Earth Ground wire (NOT A NEUTRAL) to the Ground terminal.
7.
There is NO NEUTRAL connection.
Phase Sequence
This chamber has a protective circuit to ensure the proper input power phase sequence. If the
chamber does not function with the initial wiring hookup, then reverse two of the input lines.
