KT-NCC Installation
The KT-NCC installation process consists of installing your KT-NCC and then configure it in EntraPass
Global Edition software.
To install the KT-NCC, first mount the cabinet, connect back-up power and grounding connections, then
wire all relays and controller loops to the board.
Mounting the
KT-NCC
Enclosure
The KT-NCC cabinet does not require any additional enclosures.
•
The cabinet must be mounted indoor in a secure, yet accessible, location that supports the
environmental conditions listed in the environmental specifications on Table 1 on Page 9.
•
Leave 23 cm (8 in) clearance space around the sides of the cabinet, and at least 33 cm (13 in) space
in front of the cabinet.
•
Avoid placing the cabinet near electrical or communication devices.
•
Electrical metallic tubing (EMT) 1.9 cm (3/4 in) conduit knockouts are provided on all sides of the
cabinet.
•
Install the cabinet on the selected wall using four screws fed through the mounting holes. Refer to
Figure 25: on Page 42 for details on the KT-NCC enclosure.
•
For KT-NCC UL Cabinet only
- In order for the KT-NCC to comply with UL294 section 32.1.5, the
installation technician has the responsibility of installing an AC powered LED outside the KT-NCC
cabinet and connect it to relay # 2 on the KT-NCC. The LED must be visible at all time.
Removing the
Enclosure Door
(Optional)
The enclosure door can be removed to facilitate access to the KT-NCC board and to ease installation. To
remove the door:
1.
For KT-NCC UL Cabinet only
- Remove the ground wire from the screw on the door, see Figure 2:
on Page 14 below.
2. Lift the door up until the hinges no longer touch the pins.
Note:
For KT-NCC UL Cabinet only
- When re-attaching the ground wire be sure to slide the metal
loop at the end of the wire onto the screw, then add the nut on the screw to ensure that the
ground wire stays in contact with the door.
