• Limit switches can bounce when actuated.

This

NOTE:

In order to achieve an IP-54 Enclosure Rating (splash-resistant

environment), Nordson recommends

that

you route all

PC40

input and

output electrical connections through water-tight conduit and a junction

box

Use

1 in. (2.5 em) conduit fitting, and locate the conduit center line

1 in. (2.5 em) from

the

wall.

NOTE:

Before mounting

PC40, make sure

that

you

have sufficient

space to mount it.
