See diagram below for an example of terminal box connections. When the threaded cover
is removed, the installer can have access to the wiring connections.
To properly secure the enclosure, conduit entries must be sealed according to
CSA requirements within 18 inches of the actuator
.
After making the internal wiring connections, the threaded cover must be screwed down
until the cover flange is fully stopped against the top surface of the terminal housing. Once
the cover is fully screwed down, tighten the set screw in the cover against the housing to a
torque of 10-25 in*lbs (1-3 Nm).
Grounding
English
Grounding
Fixed Protective Earth (PE) connections are required for human safety as
well as proper operation. PE connections must not be fused or interrupted. Failure to follow
proper PE wiring can cause death or serious injury. This equipment has high earth leakage
current and requires a redundant PE connection.
A PE Connection is made (as marked) inside the terminal housing as indicated in the
wiring diagram.
. There is also an external lug provided adjacent to the ¾” NPT ports for
connection of an external PE connection.

Заземяване
Свързвания към фиксирано защитно заземяване (PE) са необходими за безопасност
на хората, както и за добро функциониране. Свързванията към защитното
заземяване (PE) не трябва да имат предпазители или да се прекъсват. Неспазването
на правилата за PE свързване може да причини смърт или сериозно нараняване.
