Form 6 triple-single microprocessor-based rack mount recloser control
16 INSTALLATION AND OPERATION INSTRUCTIONS   MN280084EN   July 2018
IMPORTANT
Disconnect switches for both AC and DC circuits and 
a current transformer shorting-type terminal block are 
necessary to isolate the Form 6 recloser control for testing 
and servicing.

Customer-supplied shielded control cable
 WARNING
Hazardous voltage. Recloser and control must be solidly 
grounded. Follow all approved procedures and safety 
practices when grounding this equipment. Improper 
grounding can result in contact with high voltage, 
which will cause death or severe personal injury.  G115.1
The shielded control cable between the Form 6-TS rack 
mount control and the recloser interface junction box is 
supplied by the customer.
The maximum control cable length is 91 meters (300 feet). 
Refer to Table4 for reclose times.
Both 53 VDC and 53 VDC Common connections must be a 
minimum of (2) 12 AWG wires (Figure13):
 
53VDC connects between TB1-16 in the junction box to 
TB2-16 on the back of the Form 6-TS rack mount control 
interface power module.
 
53VDC Common connects between TB1-17 in the 
junction box to TB2-17 on the back of the Form 6-TS rack 
mount control interface power module.
All other connections can be 18 AWG wire.
ote:N The control cable must be supported along its length 
to prevent repeated movement due to wind or other 
outside forces which can damage the cable.
IMPORTANT
All external inputs to the Form 6 recloser control must be 
routed within 8 inches of their corresponding ground. During 
a surge, a potential of approximately 1.5kV per foot can 
develop in the conductors. Differences between conductor 
and ground path lengths can add additional stress to the 
control components in the event of a power surge.

Junction box and cables
The Type NOVA-TS recloser is connected to the Form 6-TS 
recloser control at a junction box (Figure8). The maximum 
junction box cable length between the triple-single junction 
box and the NOVA-TS recloser is 30 feet. Three junction 
box cables are required - one for each recloser. The junction 
box is mounted on the substation frame between the Type 
NOVA-TS Triple-Single recloser(s) and the Form 6-TS rack 
mount control.
IMPORTANT
The triple-single recloser junction box is mounted with all 
cable connections made at the bottom of the box. Donot 
invert.
