bolts and they must be retained by a lock washer and
nut on the inside of the box or panel. Alternatively, four
blind holes may be drilled and threaded to accommodate
the mounting screws, provided that the hole depth is
sufficient to achieve adequate gasket compression.
OPERATION
To ensure safe and reliable operation, MELTRIC
plugs and receptacles must be used in accordance
with their assigned ratings.
MELTRIC plugs & receptacles can only be used in
WARNING
conjunction with mating receptacles or plugs manufactured
by MELTRIC or another licensed producer of products
DANGER
bearing the technology trademark.

different keying arrangements, so that only plugs and
receptacles with compatible contact configurations and
electrical ratings will mate with each other. NOTICE
Connection
ADVERTENCIA
To connect, open the protective plug cap, align the red
DANGER
dots on the plug and receptacle bodies, insert plug into
receptacle, apply force and rotate the plug 20° counter-
clockwise(CCW). The contacts will mate and the circuit
CAUTION
will close.
AVISO
Disconnection
To open the circuit and remove the plug, press the pawl,
apply inward force and rotate the plug 20° clockwise
(CW). The plug can be safely withdrawn from the
receptacle. The plug contacts remain shrouded until after
the circuit is disconnected. Close protective plug cap to
prevent contamination by dirt, dust or other debris.
LOCKOUT PROVISIONS
The receptacle lid can be locked with a locking pawl
except PNHT.
Screw: Plug inserted or cap closed, turn the 5 /16"

MAINTENANCE
WARNING
Before inspecting, repairing, or
maintaining MELTRIC products,
DANGER
disconnect electrical power to the receptacle to eliminate
the risk of electrical shock.
CAUTION
MELTRIC products require little on-going maintenance.
However, it is a good practice to periodically perform
NOTICE
the following general inspections:
• Check the mounting screws for tightness.
ADVERTENCIA
• Verify that the weight of the cable is supported
DANGER
by the strain relief mechanism and not by the
terminal connections.
CAUTION
• Check the IP gaskets for wear and resiliency.
In wet /wash-down environments, the gaskets
should be inspected periodically (6 months) for AVISO
wear and hardness. Replace gaskets as needed.
• Verify the electrical continuity of the ground
circuit every 6 months.
• Check the contact surfaces for cleanliness
and pitting.
Deposits of dust or debris can be rubbed off the contacts
with a clean cloth. NOTICE: Under no circumstances
should the contact surfaces be filed since this will
remove the silver-nickel, butt-contact tip and degrade
the contact consistency. Sprays should not be used
since they tend to collect dirt. If any significant pitting of
the contacts or other serious damage is observed, the
device should be replaced.
Receptacle contacts may be inspected by qualified
personnel. This should only be done with the power
disconnected. Any repair or service must be performed
with genuine MELTRIC parts only.
