3 INSTALLATION
•
All electrical chassis must be safety grounded.
•
Check that all sources of power are disconnected, locked out and tagged “Out of Service” prior to beginning
installation.
•
Only qualified personnel should install this chuck control unit.
Prior to beginning, thoroughly plan your installation. Read this manual completely. The installation parts list below should aid in
your planning.
1. Mounting hardware for the control and the remote.
2. Conduit and associated hardware for AC input, chuck output and remote.
3. Remote cable: 14-conductor #22 AWG shielded cable.
4. Chuck cable: Type SO or SJO cord with proper current rating.
3.1 Mounting the Chuck Control & Connecting Electrical Power
3.1.1 Optional Remote Unit
Select a location for mounting the remote unit. The remote unit should be mounted in a location that is both safe and
convenient for the machine operator. Typically, it is mounted in close proximity to the machine controls. It is important
to keep the remote unit within fifty (50) feet of the main control enclosure and away from exposure to any fluids.
It is recommended that shielded cable be used for the remote unit wiring and that the conduit be run six (6) inches
from all other parallel conduit runs. The remote unit wiring must include a ground wire that is connected to the chassis
of the remote control and to the chassis of the main enclosure. The length of cable that is used should not exceed fifty
(50) feet. It is recommended to use 14 conductor #22 AWG shielded cable for connecting the remote unit.
3.1.2 Main Chuck Control Unit
Select a location for mounting the main chuck control enclosure. It must be located in a well ventilated area. To ensure
proper operation, ambient temperature at the main chuck control location must not be higher than 104º Fahrenheit
outside the enclosure.
Three conduits must be routed from the main chuck control enclosure; remote control cable, AC input and DC output.
Conduit sizing should be determined in accordance with all NFPA/NEC, state and local regulations by the qualified
person installing the system. The remote control cable must be kept a minimum of six (6) inches from high voltage
cables such as the AC input. The DC output also must be kept at least six (6) inches from high voltage AC wiring.
Refer to Figure 3 1.
